    Tips: The torque values output from torque sensor has large fluctuations

    1. When the torque sensor is used in the test-bed, the torque value in the testing process has a great deviation with the practical value. For example, the reaction torque sensor with a measuring range of 2000 Nm is actually loaded with 600 Nm during the measurement, but the torque sensor shows 1500 Nm, and the torque value is always staying at 1500 Nm no matter how much more load you exert. The torque value can return to zero normally after unloading. Such a kind of situation is caused by electromagnetic interference. In the operation process, the torque value always fluctuates within a certain range no matter how many loads are exerted. It is mainly because of the electromagnetic interference generated by the servo controller or motor in the field, or power leakage of the test-bed.

    2. Further confirm if the problem is caused by interference. After unloading and cutting the power supply, take the static torque sensor away, and electrify it to check if it works normally. It is suggested to use an oscilloscope or multimeter to measure if the frequency signal or analog signal of the torque output is normal. If yes, it proves that there is interference at the site or power leakage of the test-bed.

    3. Methods of solving the interference:

    1. Firstly, confirm if the test-bed has power leakage, use the AC function of the multimeter, with one test probe holding in hand contacting with the human body, and the other test probe contacting with the metal part of the test-bed to check if the test-bed, motor or other equipment has the power leakage phenomenon. In the case of power leakage, the multimeter will have a voltage display.
    2. Confirm if the motor, servo controller, frequency converter, test-bed and other equipment have ground connection (Note that it is earth ground, not power ground).
    3. The shielded wire of the sensor should have ground connection in connecting the torque sensor. If any display meter is equipped, the meter should be grounding as well. (Note that it is earth ground, not power ground).
    4. If the above solution is still unable to solve the problem, it is required to install the 1:1 isolation transformer and 1:1 filter after the power supply that power for the torque sensor and the meter.

    The above solutions of electromagnetic interference can basically solve the problems of electromagnetic interference of more than 95%.

    A reaction torque transducer is a non-rotating torque transducer that acts as a lever arm and a force transducer.
    Reaction Torque Sensor
    I was hoping for the smaller 100-300nm size.  While the 500nm model will work, it might be too large for our design.  Our max torque is 250NM.
    From: Samuel | Date: 07/11/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    If your system application is up to 250Nm, using a Sensor with 300Nm Capacity is enough. The 300Nm option will be shown on the website soon.
    Some questions about torque sensor trials
    I wanted to know what the life cycle of your product is.
    We will cycle about 100,000 times per trial, and we have multiple trials.
    Also, we have capture cards that can supply up to 10V.
    I see that the sensor can take from 5 to 15V.
    Here are my questions :        
    Do you see an issue with this type of application?
    Do you have any better product to suggest to us?
    We’d like to have the sensors calibrated either every year or every two years. Is this a service that you offer?
    From: oz | Date: 30/08/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. The life of our sensor is more than 10 million times. If the strain gauge is subjected to a relatively large force during the test and exceeds its allowable measurement range, the strain gauge may be damaged.
    2. The power supply range of the torque sensor is 5 to 15V, and an additional DC power supply is required, and the 10V of the capture cards cannot be used. If you want to collect signals, you need to use our instrument collection.
    3. We need to know: Do you want to measure the torque generated by different thrusts? Will it pan and move? How long is the move distance? Could you please describe your application structure in detail?
    4. We can provide calibration service. The calibration service is free, but you need to pay for the freight. We recommend calibration once a year.
    Could you provide answers to other original aspects of the torque sensor?
    Thank you for the information.
    I apologize as it appears that my initial request had a typo. We are sampling at 500-1000Hz, not kHz.
    With this, can you please provide answers to the other aspects of the original request? Additionally, can you confirm how the safety overloads are calculated?
    The sensor lists 120%FS on a 200NM sensor. Does that mean 240NM (120% of rating) or 440NM (120% over rating)C?
    From: nikos | Date: 19/07/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. There is no problem with our torque sensor sampling at 500-1000Hz, but the actual sampling frequency is also related to the data acquisition system you use.
    2. The sensor shows that 120%FS is 120% of the rated power, which means 240NM on the 200NM sensor.
    3. The specific service life of the sensor is related to the installation and use environment, and we cannot provide accurate data.
    If the sensor is affected by vibration, the reading will definitely be biased. Could you please tell us the specific vibration intensity in your environment?
    How are these torque sensors affected by vibration?
    I am looking to measure torque in a dynamic system with a closed loop sampling from 500-1000kHz with either model ATO-TQS-DYJN-101 or ATO-TQS-DYJN-103.
    With this, I have a few questions:
    In this application, it is critical that our latency is as close to zero as possible. Do you have any specifications on this or are both of these effectively 'real time'?
    It appears that the sensors are very similar to one another. Are there any major differences I should be aware of from an electronics design perspective outside of the obvious mounting differences?
    How are these sensors affected by vibration?
    We will likely be using whichever sensor is selected for quite some time. What is the expected lifecycle for these products as far as replacements being available? Is there any stocking that takes place in the US?
    From: arvin | Date: 18/07/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    These two models, model ATO-TQS-DYJN-101 and ATO-TQS-DYJN-103, are mainly different in structure, and the others are the same.
    But these two sensors measure static torque, and the sampling frequency is only about 10KHz, which cannot reach 500KHz.
    Question about this reaction torque sensor.
    The goal was to read the values from 0 - 5V, however it seems that the actual output is around 4.9V to 5.2V, is this due to incorrectly assigned CF value?
    From: Michael | Date: 25/05/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Please tell us how you calibrated?
    When you calibrate the torque sensor and the transmitter, you should set the range of the sensor to be consistent with the total range of the transmitter (for example, the torque range is 100NM, the transmitter should also be set to 100), and the transmission output signal 5V should be set to correspond to the CF value during calibration.
    You can refer to the attached transmitter manual, re-calibrate and test again.
    Questions about reaction torque sensor
    If I ordered your reaction torque sensor, dual flange, will you send us its 5 pin circular connector free of charge?

    Yes, we will send it to you for free.
    I have a few questions about the sensor
    I have a few questions about the sensor:
    Is there a 0-5V output on the sensor to read easily with an analog input?
    What is the recommended supply voltage?
    What is the warranty on the product, as $3000 is a lot of money?
    If I do not intend on using the RS485, should I leave the two wires unconnected?
    How exactly should I connect the RPM  /- to acquire the RPM %?
    From: Terje | Date: 15/09/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. This sensor does not have 0-5V output. If the 0-5V output is required, an external transmitter must be added.
    2. The recommended power supply voltage is 15VDC or 24VDC.
    3. The warranty is in December. (Of course, you can contact us if you have any questions during use.)
    4. Yes, you can disconnect the two wires if you don't plan to use RS485.
    5. As long as the sensor wiring is normal, to obtain RPM %. Do you need to configure the display controller?
    Information about the 20Nm reactive torque sensor
    I recently purchased a 20Nm reaction torque sensor product. I would like to understand the connection diagram for the output electrical wiring. There is limited information on your website. I see that the excitation voltage is 5-15VDC. I'm excited about this sensor with a 15VDC supply. Is the signal output a 0-15V or 4-20mA or open collector type? I do not see any output when I apply torque.
    Also, my assumption is that the sensor has a solid connection with the flange and that the flange could be permanently fixed on a surface. With this, the torque is applied in location (1). Is this correct or would torque need to be applied in location (2)?
    From: Auzer | Date: 13/09/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    2. Yes, the excitation voltage range of this torque sensor is 5-15VDC.
    3. The torque sensor's output is an MV signal. If you want the sensor to output analog signal 4-20mA, 0-5V, 0-10V, etc., you need to add a transmission. The model of the transmitter is SKU: ATO -LCTR-OAR
