What is the performance of automobile intake pressure sensor failure! ?

1, the pressure went up, but the transmitter didn't go up. Check whether the pressure connection is leaking or blocked. If not, check the wiring mode and power supply. If the power supply is normal, just press it to see if the output changes, or check whether there is output at the zero position of the sensor. If there is no change, the sensor is damaged, which may be the problem of instrument damage or other links of the whole system.

2. The output of the booster transmitter remains unchanged, and then the output of the booster transmitter suddenly changes, resulting in that the zero position of the pressure relief transmitter cannot return to the sealing ring of the pressure sensor. It is common that due to the specifications of the sealing ring, after the sensor is tightened, the sealing ring is pressed into the pressure inlet of the sensor to block the sensor, and the pressure medium cannot enter when it is pressurized, but when the pressure is high, the sealing ring suddenly bursts and the pressure sensor changes.

3. The output signal of the transmitter is unstable. The problem of this fault pressure source. The pressure source itself is an unstable pressure. It is likely that the instrument or pressure sensor has poor anti-interference ability, the sensor itself vibrates greatly, and the sensor is faulty.

4. There is a great deviation between the transmitter and the pointer pressure gauge. It is normal to have deviation, and confirm the normal deviation range. 、

5. Influence of installation position of micro differential pressure transmitter on zero output. Because of the small range of micro differential pressure transmitter, its sensitive components will affect the output of micro differential pressure transmitter. During installation, the pressure sensitive part of the transmitter should be perpendicular to the gravity direction. After installation, the zero position of the transmitter should be adjusted to the standard value.
