Disposal Method of Capacitive Transmitter on Site(II)

2. mA reading is high or low

At this moment, you need to check the degree of pressure variable; perform 4-20mA output adjustment.

3. The transmitter does not return to zero after the input pressure has no response or pressure relief

Check the transmitter's power supply voltage, verification equipment and setpoints (4mA and 20mA points); check the pressure interface is not a leak may be blocked; check the wiring method and power supply, if the normal in the sensor sensor zero output , Perhaps a simple pressurization to see if the output is not changed, there is a change to prove that the sensor is not damaged.

4. The pressure variable may be low or high

Check the pressure transmission is not a seizure; view the verification equipment and sensor adjustment; check the car damping and electromotive force disturbance.
