Pressure up, the transmitter output falters

In such cases, you should first check the pressure connections for leaks or is blocked, if confirmation is not, check the wiring, such as the wiring is correct then check the power supply, such as the power supply is normal and then look at whether there is zero position sensor output, or look for simple pressure whether the output changes, there are changes prove Engine Temperature Sensors is not broken, if no change in the sensor that has been damaged. Other reasons for this situation may also be damage to the instrument, or other aspects of the whole system problem. Pressure transmitter output does not change, then a sudden change in pressure transmitter output, the transmitter zero relief go back. Produce this phenomenon is most likely caused by the pressure sensor ring in our customers encountered several times. General specifications reason is because the ring (too soft or too thick), Motor Position Sensor tightened, the sealing ring is compressed inside the mouth to the sensor impulse blockage sensors, pressurized pressure medium entrance, but a lot of pressure when a sudden impulse to open sealed circle, the pressure sensor under pressure and change, and the pressure is reduced again, seals and return blocked impulse mouth, no residual pressure release, the sensor zero position and get down. Exclude this reason the best way to remove the sensor directly look at the zero level is normal, if normal replace the seals and try again.
