    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?
    From: Connor | Date: 08/04/2020
    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.

    what is the zero torque output voltage of the 0-10V option?
    I want to get negative torque in case of reversing direction, do I need to use  /-5V output?
    From: Witucki | Date: 29/06/2021
    Was this review helpful? Yes No (1/0)
    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.
    Design of digital rotation torque sensor
    For your ATO-TQS-D03 digital rotary torque sensor, is this a contactless design or with slip rings?

    ATO Responded
    Yes, our ATO-TQS-D03 torque sensor is able to measure up to 300 mNm with a minimum resolution of 0.1Nm when the measuring range is 0.1NM.
    Usually the measurement resolution is 1/1000 of the measuring range. So, what is the measuring range for customer requirements?
    Which torque sensor do you think is more suitable for us?
    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. Besides, we would like to know the price and lead time for the digital rotary torque sensor or any other you consider that fits our application better.

    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. The bottom thread hole is fixed, and the threaded holes on both sides can be fixed. The premise is that you must maintain that transparency when installing, and the transparency must be good.
    2. Can be installed.
    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.
    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?

    Use for continuous rotation?
    May I ask for a clarification on the maximum rotating angle specification? "2.60*10rad (0.149°)". Can this sensor be used for multiple rotations?

    2.6 * 10 rad = 26 rad = 1490 deg
    What does the 0.149° value reprepsent?
    From: Timothy | Date: 05/05/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. This torque sensor can be rotated multiple times without limit.
    2. 0.149° means: The maximum deformation angle generated by 1Nm at 2.6*10rad rotation arc is 0.149°.

    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. Does the other end of the sensor have a rotating disk of known weight and moment of inertia as a reference?

    On the other end of our torque sensor spectrum, we recommend a reed brake. In order to recommend a suitable brake model for you, we need to know the following.

    1. What is the output torque and what is the maximum speed of this small DC motor?
    2. What analog signal (±5V, 0-10V, 4-20mA, RS485, RS485 & ±5V, RS485 & 0-10V, RS485 & 4-20mA) do you need to output from the torque transducer?
    Is this Digital Rotary Torque Sensor achievable for my application?
    Is this Digital Rotary Torque Sensor achievable for my application that requires 4 torque transmitters to be mounted on the shaft between the gear drive and the equipment. 4-20mA output is required. This is also in Class 1 Div 2 group C/D.

    1. What is the range of Nm measured by these 4 torque sensors in the system application?
    2. What is the measurement accuracy?
    3. Is 4-20 mA signal for 4 sensors outputting combined or 4-20mA for each sensor?
    Please note that our torque sensor is not Class 1 Div 2 group C/D, it is gas explosion-proof standard.
    Looking for help choosing a rotary torque transducer for testing a small experimental wind turbine.
    I need a range of 0-50 Nm and 0-1200 rpm that can send a signal 0-5V or 0-10V to a data logger. Also needed will be necessary shaft couplers to go from the transducer to 25mm shafts. Any assistance in selecting the correct equipment is appreciated.

    Our digital rotary torque sensor with 50Nm capacity and 0-10V output signal will meet your requirements.
    Cold Performance
    We use multiple 100 Nm sensors and we are quite content with them.

    My question is, can we operate these sensors in colder temperatures than -10℃,  i.e. will they be operational in -50℃ with an error?

    What is the IP classification?

    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!
    From: Womin | Date: 06/03/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    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.
    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.
