During the use of the sensor, in addition to normal losses, there will also be sudden failures caused by various reasons. What causes sensor failures: deviation failure, impact failure, open circuit failure, drift failure, short circuit failure, periodic interference, nonlinear death. zone failure. This article summarizes the 7 major causes of failures for you as follows:




1. Deviation fault: This fault is caused by factors such as bias current or bias voltage.


2. Impact fault: This fault is caused by factors such as random interference, surges, spark discharges in the power supply and ground wires, and burrs in the D/A converter.


3. Open circuit fault: This fault is caused by factors such as disconnection of the signal line or unconnected chip pins.


4. Drift fault: This fault is caused by factors such as temperature.


5. Short circuit fault: This fault is caused by bridge corrosion, line short circuit and other factors caused by pollution.


6. Periodic interference: This fault is caused by factors such as 50 Hz interference from the power supply.


7. Nonlinear dead zone fault: This fault is caused by factors such as amplifier saturation and nonlinear links.




The above are some common causes of sensor failure. Understanding and avoiding these problems will help improve the reliability and life of the sensor.
