    Rotary torque sensor installation:
    Rotary torque sensor horizontal installation and vertical installation
    Tips: How to install a rotary torque sensor?
    The steps of torque sensor installation:

    1. According to the connection form of the shaft and the length of the rotary torque sensor, determine the distance between the prime mover and the load. Adjust the distance between the axes of the prime motor and the load relative to the base level, enable the axes concentricity to be less than Φ0.03 mm. Fix the original motor and load on the base level.
    2. Install the couplings on the shafts respectively.
    3. Adjust the distance between the torque sensor and the base level, enable the concentricity of their axis (torque sensor, motor and load) to be less than Φ0.03 mm, and fix the torque sensor on the base level.
    4. Tighten the coupling and complete the installation.

    The requirements of torque sensor installation:

    1. Power equipment, torque sensor, and load equipment should be installed on a stable foundation to avoid excessive vibration, otherwise, data instability, measurement accuracy reduction, and even damage to the dynamic torque sensor will probably occur.
    2. Choose the elastic pin coupling or rigid coupling for connection. When the vibration is serious or the concentricity is greater than 0.05mm, it is recommended to use a flexible coupling and install a bearing support at the left and right ends of the torque sensor.
    3. Adjust the centre height and concentricity of the power equipment, load, and torque sensor separately, which is required to be lower than 0.05mm, and then fix.

    Matters needing attention:

    1. The torque sensor should be installed in an environment where the ambient temperature is 0 ℃ ~ 60 ℃, the relative humidity is less than 90%, and there is no flammable or explosive product.
    2. It is not suggested to be installed in an environment with strong electromagnetic interference.

    Use our digital load cell amplifier. SKU: ATO-LCTR-OAR so can get 0-5V signal.

    Torque sensor parameters and performance issues
    I want to buy 5 of your ATO torque sensors, output  /-5V. When I checked its user manual, I found that there are pins 7 (RPM ) and 8 (RPM-) on the last page to read the machine speed in RPM.
    1. What is the voltage level of these pins?
    2. How to use my microcontroller to read these pins to calculate the machine speed?

    ATO Responded
    1. The voltage level of these pins is 5V.
    2. The single-chip microcomputer can use the counter or external interrupt to read the speed signal. It is recommended that the single-chip microcomputer increase optical coupling isolation to reduce interference.
    Hello, I would like to consult your rotary torque sensor.
    Hello, I am planning to use your rotary torque sensor in line with a stepper motor to measure torque applied to electrical connectors. I have noticed that some similar test bench layouts utilize a brake or clutch in conjunction with the transducer. Can you explain to me why this might be necessary? The torque we are applying is small (Max 7-8 n*m). We are also using a stepper motor to reverse directions during the testing process. Do you think it would be necessary to use an eddy current brake or clutch with this rotary torque transducer to obtain accurate and consistent measurements or do you think the use of a stepper motor may eliminate the need for the use of a brake or clutch? Also, can you recommend shaft couplings for this type of application? I couldn't find much information on the use of clutches and brakes with torque sensors/transducers. Any help will be greatly appreciated. Thanks.

    If the rotary torque sensor is only used to measure the torque of the electrical connector, there is no need to use a brake or clutch in combination with the sensor. Generally, the brake is used to test the driving torque of the motor.
    I want to know about your torque sensor.
    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: Munge | Date: 17/12/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Unfortunately, it 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.
