I have a 20000N range pull pressure sensor and an 2000N range amplifier. I think the two are connected. My actual requirement is 2000N, and the 18000N behind the sensor is not required.In the process of calibration, problems were found. First of all, I switched zero. When I applied the force of 500N, the value on the computer was 35N, and then I switched it up. When I was transferred to the value of 98N, I couldn't tune it any more, no matter how the potentiometer turned.Please help me explain the reason for this phenomenon, thank you.
Your pressure sensor has a range of 20000N, but the sensor has a parameter that triggers the force to see if the trigger power is set at a small value.
Obviously, the mismatch is like a child wearing an adult shoe.20000N sensor and 2000N amplifier has its own sensitivity, generally not consistent, and the force of 500N for 20000N, the output signal is very weak, if not up to the driver, not even output. After the amplifier process, the error will be great. It is recommended that belt changing weighing sensors be several hundred dollars and not very expensive.
You can use the 4000N sensor at most, and you can use the 20000N sensor
