How to zero the pressure sensor?
The zeros of certain process requirements or production processes are different. Is it a measure of the pressure of the liquid? The mechanical property of the hydraulic pressure is better. Or regular contact pressure? The installation of zeroing circuit!! A little more complicated!
This you say is wrong type? It could be pt124. The model is rather messy now. If it is a high temperature melt pressure sensor, the zero adjustment potentiometer is exposed outside the shell. Only the "zero" potentiometer can be adjusted, but the full potentiometer can not be adjusted randomly. The high temperature melt pressure sensor has 80% calibration lines. If the potentiometer needs to be adjusted, the two calibration lines can be shorted and debugged.
According to the type, adjust according to instruction.Unless you give a specific model, others can not specify.No pressure sensors of this type have been seen in tb124. Usually in the circuit of assembling sensors into the transmitter, the zeroing circuit is installed. Because the so-called zero points usually have different definitions.
