500 Nm Digital Rotary Torque Sensor Troubleshooting

Hello,
We recently purchased a 500 Nm Digital Rotary Torque Sensor with RS485 &±5V output along with its software, but we have encountered two issues:

The ±5V output is volatile and noisy, even when using shielded equipment. We've only managed to get usable data by adding a low-pass filter, but it doesn't fully resolve the issue. When using the software, the displayed readings are 1/10th of the sensor's actual value.

Can anyone help us figure out the possible cause? Thank you in advance!

For the signal noise issue, have you tried using a magnetic ring on the signal line? Also, what is your testing environment? Are there any potential sources of electrical interference nearby?

Regarding the software display issue, you can adjust the decimal point setting in the software to correct the torque reading.

I’ll order magnetic rings and install them to see if that helps. We have been testing the sensor in a normal indoor environment, but in our actual application, it will be connected to a large electric motor, which might introduce additional noise.

To reduce signal interference, we recommend:
1. Using two magnetic rings to shield the sensor’s signal cable.
2. Keeping the sensor signal cable separate from the motor cables. Do not bundle them together, as the motor cables can cause significant interference.
