    Torque sensor dimension (unit: mm):

    Micro reaction torque sensor 0.5Nm to 150Nm dimension
    Tips: Torque sensor has abnormal torque or high torque value on torque controller

    When torque sensor is connected with a controller (meter), the controller display abnormal torque or high torque value.

    1. Such a problem is common because of the non-correspondence between the torque meter range parameter and torque sensor range. Firstly check if the torque sensor is OK, disconnect the sensor away from the meter, and check the original signal of the sensor with the oscilloscope or multimeter. Check if the sensor zero point is 10 kHz, and check if the frequency value is normal after loading. If it is normal, the problem lies in the torque meter parameter.
    2. Check if the meter parameter range adjustment is consistent with the sensor range. For instance, when the reaction torque sensor is in full range 10Nm, the meter parameter range value is 10.
    3. If the meter display torque is fixed and the L red light on the panel is always ON, the problem lies in the meter alarm parameter settings. The upper limit alarm and lower limit alarm. Check if the meter parameter AL1F and AL2F parameters are 0. 0 is the upper limit alarm, it means to alarm when it is higher than the alarm setting value. 1 is the lower limit alarm, it means to alarm when it is lower than the alarm setting value. If set to 1, as long as the torque setting value is not reached, the meter has always been in the alarm status, and display has no reaction.

    Does the toque sensor measure torque in both directions?

    Thanks in advance

    Yes, it can measure torque in both directions.
    What is the maximum axial load?
    What is the maximum axial load your sensor can tolerate?
    I'm asking about your model ATO-TQS-S04
    With 3Nm FS
    I need a new one

    The maximum axial load the sensor can bear is 50kg.
    How to connect a shaft to the torque sensor?
    I had a question regarding how a shaft could be connected to the micro torque sensor. Is the sensor hole a through hole? If so can a shaft run through the sensor so that you input the shaft through one end of the shaft and it exits the other end of the sensor?
    From: Shane | Date: 13/11/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, the sensor is through-hole. A rotational force is applied in the opposite direction (or a relative force is generated) through the fixing holes on the end faces of both sides of the fixed sensor, and the sensor outputs an analog signal.
    Is there a manual of torque sensor you can share?
    I recently purchased the 0.5 Nm version of this torque sensor.  I'm get involved in calibration and testing. Is there a manual you can share? I know there are calibration set screws for zeroing and gain.

    The static torque sensor you purchased only needs to be calibrated at the acquisition end (data collector or transmitter connected to the sensor).
    Calibration instructions are Not included with the sensor unless you purchased a data collector or transmitter.
    Do you provide calibration certifcate for this type of torque sensor?
    I am interested in buying a 10 N-m reaction torque sensor. What will be the accuracy? Do you provide a calibration certificate for this product?
    From: shangcheng | Date: 28/04/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    The accuracy is about 0.03%, and a calibration certificate is provided after shipment.
    I would like more information on the signal outputs EXC /- and SIG /-.
    I need a better understanding of the signal outputs of the 0.5-150 Nm Micro Reaction Torque Sensor in our application. I would like more information on the signal outputs EXC /-  and SIG /-. Is the range 0 to 20mV for each, and what does each signal represent?  We are looking to design our own electrical interface circuit for processing the output. If you have an example electrical interface app note it would be very helpful.

    ATO Responded
    Regarding the signal wiring, EXC+/- is the excitation voltage; SIG+/- is the output signal line, and the default output signal is 0-20mv. If you would like to measure forward and reverse, it is recommended to configure the sensor with a transmitter to output 0-±5V, or 4-12-20ma for measuring forward and reverse torque. See transmitter specifications:
    Connection of 0.5-150Nm micro torque sensor
    Can your micro torque sensor be set up 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: Deck | Date: 14/05/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Unfortunately, can't be connected like this, because if the other end is not connected, there will be no data to compare between the input and output, and the reading will be abnormal.
