Analysis of the problem of unstable signal and no output when connected to power on of wireless pressure sensor [Copy link]

Wireless Pressure Sensor is a battery-powered, high-precision intelligent pressure measuring instrument with wireless communication function. It can be widely used in industrial fields such as petroleum, chemical, electric power, metallurgy, pharmaceutical, and food. It is an ideal upgraded product for traditional pressure gauges and traditional pressure sensors, and an ideal pressure measuring instrument in the field of industrial automation.

Wireless Pressure Sensor may encounter various minor problems in long-term use, such as unstable output signal, no output when powered on, etc. The output signal of the wireless pressure sensor is unstable (1) The output signal of the pressure sensor is unstable

Fault inspection and analysis: The reasons for the unstable output signal are as follows: ① The pressure source itself is an unstable pressure; ② The instrument or pressure sensor has poor anti-interference ability; ③ The sensor wiring is not firm; ④ The sensor itself vibrates very strongly; ⑤ The sensor is faulty. Through judgment, it is found that the sensor of the instrument is faulty. Fault handling: Replace the transmitter. WirelessPressure sensor No output after power on Fault inspection and analysis: The possible reasons for the transmitter to have no output after power on are: ① Wrong wiring (both the instrument and the sensor should be checked); ② The wire itself is open or short-circuited; ③ The power supply has no output or the power supply does not match; ④ The instrument is damaged or the instrument does not match; ⑤ The sensor is damaged.

Wrong wiring (both the instrument and the sensor should be checked); Wrong wiring is not the cause of the malfunction due to normal use
