How to deal with the pressure transmitter output problem

Pressure transmitter chooses import dispersed silicon or ceramic core body as pressure detecting element, can replace the traditional remote transmission pressure gauge, hall element, differential transducer, due to the transmitter in the process of production has a factor that cannot be compared by, so when rendering problem, we will handle in time. Below we will to know how to deal with the output of the pressure transmitter.

pressure transmitter output does not change, the pressure transmitter output again but change, zero pressure transmitter back to not go to, may be the result of the pressure sensor sealing ring. Is usually due to seal standard reason ( Too soft or too thick) , tighten the sensor, the sealing ring is compressed to the sensor pressure inside block sensor, pressure pressure medium into not to go, but a lot of pressure when Russia made sealing ring.

and subject to change by pressure, pressure transmitter and pressure drop again, seal and return plug pressure, residual pressure release out, thus sensor zero come down again. Rule out the reason is the best way to remove the sensor, can directly observe the zero is normal, if it is normal to replace seal to try again.
