analysis of Consequences and causes of insulation damage of load cell or weighing sensor

Load cell insulation damage mainly in the weighing process, the following two:
1. Said digital display device is unstable, the finger touch sensor, the value of said jitter analyzer, a bridge circuit is mainly due to the elastic
Poor insulation between the body [1]
, Destroyed the balance of the bridge, high-current film produced by thermal drift, power process due to the influx row, leading
Changes in the sensor zero, zero drift increases, the nonlinear increase of the bridge can not even tune equality.
2. Digital display instrument represents the value of instability, finger touch sensors or load cell, meters showed no reaction, instrumentation and sensor bridge
Insulation resistance between qualified. This is mainly because of the bridge due to the internal insulation breakdown [1]
, Strain gauge solder, solder joints between the wiring board, electrical
There is leakage phenomenon between the cable terminal and the circuit board
