    How Torque Sensor Outputs Working with Software

    A torque sensor is a device used to measure torque. Its working principle is to detect the torque acting on an object and then convert it into an electrical signal for output. These electrical signals can be read and input into a computer system, analyzed and processed by specialized software to obtain accurate torque values. This video shows how to operate the torque sensor and its dedicated real-time monitoring software, as well as five frequently asked questions about the specific operating steps.

    Torque sensor analog output wiring experiment

    The experiment is mainly to verify the performance and accuracy of the torque sensor. The torque sensor force measurement range is from 0.1Nm~5000N.m, output 0~5V/0~10V/4~20mA/Modbus, etc.

    1. To see the amount of torque from the drill, what is the torque measurement accuracy requirement? And what is the speed range (rpm) for system testing? Our digital torque sensor is very suitable for your use.
    2. You can apply resistance through a magnetic particle brake paired with a magnetic particle controller. Do you have any other requirements for magnetic powder brakes?
    RPM vs. Torque and Power
    Hello,

    I am interested in purchasing the 500nm version of this but would like to understand its capabilities a little more.

    Does the sensor provide feedback allowing adjustment in RPMs to take readings from free speed down to stall?  From what I see it appears to just output current speed, torque and RPM, is this correct? I would like to collect the data and be able to graph it to analyze torque and power vs. RPM curves.

    I am working with a 200 ftlb air ratchet for industrial applications and need to understand the power output at various RPMs.

    ATO-TQS-D03 can sample torque and RPM at the same time and calculate the real-time power. However, the sampling rate of RPM is 25Hz at maximum, and the sampling rate of torque is 1KHz, so the rate of generating the real-time power data can only be 25Hz. Does this sensor meet your requirement?
    Help me to Digitalized my rotational torque data.
    1. I want to check the torque of my product within the range of 1-9 Nm (Spec range). I plan to attach it to a jig socket, insert my product, and manually rotate it by hand through a 360-degree angle. Can this sensor provide and transmit the average torque data as a single value after rotating it 360 degrees?

    2. Which option should I select based on the application described above?

    3. Do you have any authorized dealers in Malaysia?

    If your maximum torque is less than 10Nm, then you can choose the 10Nm specification. Also you can purchase the RS485 interface version, which can output a digital signal, you can read the real time torque information, and you can also purchase our software to monitor the real time torque.
    Of course our customized version shows the average torque. If you need customized version, please contact us at sales@ato.com (America), service@ato.com (Europe & Asia & Africa).
    We have no distributor in Malaysia for the time being.
    We are hoping for your response on this.
    We have a torque sensor from ATO with the software.
    We have some questions regarding the ATO software 200 torque reading from the torque sensor

    Question 1
    It indicates a transfer rate of 500 readings per second at 38400 bps. However, in Excel, the software seems to send approximately 200 readings per second. The question arises: is there a relationship between the time and the torque/RPM data transmitted by the torque sensor? Essentially, are the readings (1 to 217) as per Excel sheet from the torque sensor progressively increasing over time?

    Question 2
    We have inquiries about the correlation between RPM and torque sensor, as in our data, there are instances where RPM is rising while torque lacks any recorded readings.
    From: Max | Date: 06/02/2024
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. Regarding the amount of data, the manual may be a little wrong.

    If you want to achieve a transfer rate of 500 readings per second, the torque sensor baud rate needs to be changed to 57600, and the software must also be changed simultaneously.

    2. Regarding the increase in speed but No change in torque (according to the data sheet you provided, the torque has Not changed).

    This means that only the speed of your motor has increased at this time, but your load has Not changed, that is, the torque has Not changed.
    I need some help

    Question for the rotary torque sensor
    I'm interested in purchasing the rotary torque sensor

    I have two questions:
    1) Is the calibration certificate NIST-traceable?
    2) Can you point me to a description of how the associated software works? I'm assuming I can access the Serial Port data with or without the associated software right?
    From: logan | Date: 08/01/2024
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. We can Not provide NIST-traceable certificate, we can provide IAS certificate, is that acceptable?
    2. Associated software communicates with the sensor through RS485 port, and of course you can refer to the comm protocol and realize the communication all by yourself.
    use for the high accuracy measurements.
    For our case, it won’t be practical to access the sensor and reset manually in every power cycle. So, is it OK if commanded by the PLC after each power ON through RS485 channel? We expect a high stability of sensor as the device we designed is intended to use for the high accuracy measurements.

    Powder brake can get out of alignment over time?
    This powder brake can get out of alignment over time (or with certain use cases)? If so, we do we need to do exactly? Tap is with a rubber hammer to redistribute the powder?

    This powder brake is used for braking, as long as it can produce brakes normally, it can be used. As for the deviation of the brake installation center, it is related to factors such as your system installation structure and application strength. This powder brake input voltage is rated at 24VDC, if you lower the voltage it will also pull down the brake output power.

    The PLC reads the torque and rotational speed of the torque sensor through 485 and then sends the read torque and rotational speed to the external display screen, all of which require writing a communication program. Unfortunately, we do not provide these.
    How the data is to be read from the sensor to the PLC?
    Hello, I am trying to communicate the torque sensor to a PLC through RS485, but I cannot communicate.
    It is a Panasonic FP0R plc. What are the addresses in decimal to place in the plc so that it can read torque and rpm?

    I'm looking for a suitable torque sensors
    I'm looking for a pair of torque sensors that can measure shaft torque on either side of a gearbox, running in both directions.
    Our configuration is motor - torque sensor - gearbox - torque sensor - load.
    On the high torque side we will have a maximum torque between 240 and 310 Nm (we have flexibility in the system design right now to allow for that range of maximum torques) and on the low torque side, we have a maximum of torque of 100 Nm with a maximum angular speed of 165rpm.
    We were initially considering rotary torque sensors for both sides, however, we are budget conscious and so we also wanted to consider using a torque reaction sensor on the motor side.  
    How do the two compare in performance, would having a torque reaction sensor connected between the motor stator and the frame the motor is mounted on seem like a suitable application for such a sensor?
    I also wanted to discuss accuracy and reliability, looking at the prices on your website your products are significantly less expensive than competitors I just wanted to discuss that, and any impact the low cost may have on your sensor's accuracy and/or reliability.
    If you believe that you have any products that are suitable, can you please provide us with budgetary and lead time estimates to Toronto, Canada?
    Lead time is important to us and we likely can only accept a maximum lead time of 4 to 5 weeks due to project constraints.
    We intend to use a Labjack T7 Pro to read an analog voltage as the torque transducer output, if possible.

    Question about Modbus RTU communication
    Hello! I purchased one ATO-TQS-DYN-200 sensor and I want to interface it to my custom-made PCB, via a MAX485 transceiver: on one side I connect the signals A and B coming from the sensor, on the other side I will connect the Rx, Tx and DE/RE to my PCB, so that I will be able to read the measurements of the the sensor using Modbus RTU protocol. During my implementation, I am noticing that when the signal DE/RE is low, the signals A and B are very noisy and this causes problems in the reading of the reply coming form the TQS-DYN-200. I can see this noise using a logic analyser.
    Could you help me solving the issue?

    Is there a way to decrease the torque sensor friction?
    I have purchased the a rotary torque sensor presented in the link https://www.ato.com/rotary-torque-sensor-10000-nm#quickTab-reviews for 0.1Nm maximum torque like 2 years ago.
    I didn't use it since then, now when I'm using it the shaft looks to be heavy for a 0.0001Nm resolution and a major portion of the torque is lost due to the torque sensor friction.
    Is there a way to decrease the sensor friction (by lubrication or something) and how?
    And is it normal for the shaft to be that heavy?
    Note: I can provide a video showing how heavy is the sensor rotation.
    From: boris | Date: 15/06/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    We think it's because of the increased starting torque friction that you've had for a long time without using it.
    You can use a heat gun to heat the bearings at both ends of the sensor, and then run the sensor at about 2000rpm without load for 20 minutes, and then check whether this can reduce the starting resistance.
    Where can I find torque sensor coefficient?
    Currently I am in Hobart Indiana to finalize our FAI preparations. I have one questions though on how to calibrate the sensor. I am particular looking for the “coefficient” mentioned in your user manual on page 3. Where can I find this value on interface 1?
    It probably has a different name as no “coefficient” is mentioned. Can you assist?
    If possible, please send screenshots to easy resolve.

    1. The sensor has been calibrated before leaving the factory, as long as the sensor is not overloaded and the torque is not faulty, so you do not need to calibrate. Calibrating the sensor yourself is cumbersome and requires calibration rods and weights.
    2. The coefficients have been calibrated at the factory, and we do not recommend you to modify them unless necessary. If the parameters are disordered due to improper operation, you can restore the factory settings by pressing "K2" 5 times continuously under the main display page.
    Torque sensor tolerance calculation sheet
    Thanks a lot for your response and quotation.
    Meanwhile we created a tolerance calculation sheet, which is attached as excel file.
    We need to understand if your product is capable to measure our stepper motor from 2 Nm to approximate 20 Nm.
    May you check this calculation sheet with your tech team, if it is correct?

    1. Yes, we check that the tolerance calculation sheet is correct and can be achieved.
    Now you choose the torque sensor ATO-TQS-DYN-200, which can also realize this function.
    2. About torque sensor ATO-TQS-DYN-200, do you need to configure data acquisition software?
    We can provide the calculation table test report similar to the attachment for your reference.
    Speed Sensor Readout
    I have very similar question about reading out the speed sensor of my DYN-200 using digital counter. I didn't realize that the OC was the default option and I actually need TTL. How can I convert the signal so that my TTL device can read it out?

    Some question of torque sensor
    For the output speed of this sensor, the specifications state the ''OC'' output is standard configuration, and 5V TTL output is optional.  
    Does ''OC'' mean open collector?  Also, how does the 5V TTL output option get implemented?  
    Is it a different part? Thanks.
    From: lisa | Date: 06/06/2023

    ATO Responded
    Yes, OC output refers to open collector output. When using OC output, it is necessary to add a pull-up resistor to the collector. The pull-up resistor can be selected between 1K-10KΩ. Generally, a 5.1KΩ resistor is selected as the pull-up resistor. Please refer to the attached circuit diagram.
    We do not recommend you to use 5V TTL square wave output, otherwise the sensor will burn out if the circuit is connected incorrectly.
    Some questions about rotary torque sensor
    I am writing to ask 2 questions regarding the ATO-TQS-D03 and the DAQ software provided by ATO.
    We have been conducting some torque measurements on a system and I had a question regarding the torque sensor displayed numerical values on the LCD display versus the recorded numerical values in the DAQ software. I noticed that both the RPM and torque measurements in the DAQ software are recorded as 10x larger than the displayed and as far as I can tell true values.
    I have reviewed all the DAQ software settings and I cannot clearly find a parameter that would allow me to adjust the DAQ recorded value to the true value which is 10x lower. Is there a way to change this setting in the DAQ software so that I don't have to adjust the numerical values after I export them? Is there a setting that I can adjust on the torque sensor itself in the parameter settings that may be able to modify the values to the true value when being sent to the DAQ software?
    My second question is about some of the measurements that we have been getting on the system we are testing. I have provided three pictures, one of the simplified system and a screenshot of the torque measurements. My supervisor is curious if, given the system we are testing, in your experience do the oscillations in the measurements appear generally correct to you? With respect to the values in this plot, I actually divided the raw RPM and torque values by 10 to get the graphed values which are the same as the displayed values on the LCD and what seem to be more theoretically correct to the values we were anticipating.
    I provided a third picture of the torque measurements of a radial bearing supported screw that I conducted some torque measurements on and we were wondering if you might be able to shed some light on why the values are oscillating so regularly, we have some ideas but the team wanted me to reach out to the experts to hear what you thought.
    The torque and RPM are different in each graph but the legend is at the bottom of each picture. Any help would be greatly appreciated!
    Just for reference we are using the ATO-TQS-D03 with 5N-m capacity,  /-5V output and we are purchased the USB to RS485 cable pus software that is supplied by ATO.

    1. The torque decimal point and rotational speed decimal point in the software should be adjusted until the torque sensor shows synchronization.
    Because this software actively uploads integers, but the torque range is different, you need to manually change the decimal point.
    2. Regarding the regular vibration you mentioned, it should be that the coaxiality of the equipment is out of tolerance, and the difference in coaxiality should be less than 0.05mm.
    Please adjust the center of the mechanical installation.
    To make sure some questions
    To make sure, I would like to ask again whether we are both talking about 30 times gravity and not about grams. Can you please confirm that again?

    Capacity: 0.1Nm. The axial direction of this sensor can withstand a maximum load of 10 times, less than 30 times.
    In our experiments
    We would like to use the digital rotary torque sensor in one of our experiments with the axis vertical. Can you tell us if it can withstand a momentary load of 30G in this position?

    Yes, the axial direction of this sensor can withstand a momentary load of 30G in this position.
    Do you provide the connector/cable ?
    I'm interested in using your torque sensor in a test jig we are building to cycle test a hinge. We would like to actuate the hinge (both clockwise and anticlockwise) at approximately 0.1 to 1 rpm over the range of about 180 degrees, and measure a peak torque between 2-3 N.m in both directions. We are intending to characterise the average and peak torque that the hinge requires over a large number of cycles.

    In particular, I was looking at the 5 N.m model with the RS485    /- 5V option - would this work for our application ? Is the 5V output directly from an amplifier (ie analog) as opposed to generated by a DAC?

    Do you provide the connector/cable ? We do not need the USB version of the cable or the software, as we have a custom system it will be integrated with (RS485 is already present)

    Could you please also tell me if you have any information on the number of cycles / the lifetime of the device?

    1. ATO-TQS-D03 can be tested according to your requirements, please refer to the link: https://www.ato.com/rotary-torque-sensor-10000-nm
    2. “I was looking at the 5 N.m model with the RS485 + +/- 5V option - would this work for our application ?”
    It depends on what signal you are collecting.
    “Is the 5V output directly from an amplifier (ie analog) as opposed to generated by a DAC?”
    485 signal and analog can be output at the same time.
    3. Our sensor comes with a 3m signal line by default.
    4. Sensor lifetime: If it is not used beyond the range, the life span is 1 million times.
    Can this equipment output PEAK readings of torque?
    I’m currently working on equipment for capping operations and am looking to implement a sensor that can provide readings for torque and RPM of a main shaft. I saw that ATO offers digital rotary torque sensors (https://www.ato.com/rotary-torque-sensor-10000-nm) and had a few questions regarding the device.

    Can this equipment output PEAK readings of torque? One of the key metrics for my equipment will be maximum torque applied before the operation ends
    Can this device be mounted so that the shaft is vertical? Could the red housing be left hanging free in the air or will it have to be mounted to some supporting fixturing?
    Do the torque sensors only come in these keyed shaft configurations?

    Please let me know if you are able to answer these questions!

    1. PEAK readings of torque need to be equipped with instrument ATO-D054
    2. Can be installed vertically. The shell needs to add a baffle to prevent rotation.
    3. The output shaft of the torque sensor is equipped with keyed shaft dconfigurations.
    Please refer to the figure below for the physical picture of the instrument.
    Cold Performance
    We use multiple 100 Nm sensors and we are quite content with them.

    I am interested in purchasing a digital rotary torque sensor
    I apologize in advance. I am not at all in the field of testing rotary systems. I am interested in purchasing a digital rotary torque transducer. What I am asking is what reference load is recommended at the other end of the device. I would like to connect a small DC motor at one end and measure its torque/rotation per minute for a given voltage input.

    Negative torque on 4-20mA outpput
    We are using a 4-20mA output sensor, and we want to read torque in both directions. It seems the 4-20mA only supplies the absolute value. Is there a way that we can set the 0Nm at 12mA and get both positive and negative readings around that point?

    Questions about torque sensor
    I am integrating the torque sensor ATO-TQS-D03 in a design.
    Per my calculations, the torque value to be measured could go up to almost 100Nm (93).
    What happens if we exceed this value due to the starting torque of the driving system?
    Do we just get bad reading, or is there a risk of mechanical or electrical damage?
    From: Mrsdish | Date: 03/01/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    If you exceed this value due to a starting torque of the driving system, it will cause the internal circuit board failure of the sensor or overload damage.
    We recommend that you choose two to three times the rated range of 100Nm. If the system starts with a high torque, you can choose 0 to 300Nm.

    My name is Erlantz Otaola and I write on behalf of added value solutions, a company devoted to developing mechantronic equipment for big science and space. Currently, we are looking for a torque meter for a bench we are developing. This torque meter should measure up to 300 mNm with a minimum resolution of 0.1mNm. Looking at your page, we have come across the digital rotary torque sensor, which seems to fit our purpose. However, we would very much appreciate your assessment of this.

    ATO Responded
    Yes, you are right. If want to get negative torque in case of reversing direction, you need to use +/-5V output signal instead of 0-10V. So, when the +/-5V output, the positive torque will correspond to positive voltage and reverse torque to negative voltage.
    Torque sensor connection
    Can your torque sensor be setup such that one end is connected to the motor while the other end is connected to nothing? What sort of reading will I get if this is the case?

    Was this review helpful? Yes No (0/0)
    ATO Responded
    Unfortunately, can't be connected like this. Because if the other end of the rotary torque sensor is not connected (no load equipment), there will be no data to compare between the input and output, and the reading will be abnormal.
