the fault phenomenon

fault judgment

judgment method

1

display data drift

1. The signal cable is damaged

2. Virtual welding, poor contact

3. Poor insulation

1. Check whether the exposed signal cable is intact.

2. Measure whether the input and output resistance is normal and stable;

3. Check whether the insulation is normal.

2

zero output signal is too large

1. The bridge is disconnected

2. The overload

1. Check whether the sensor is deformed.

2. Measure whether the input and output resistance is normal;

3. Measure resistance symmetry.

3

no signal

1. The signal cable is disconnected

2. The sensor bridge is disconnected

1. Check whether the external signal cable is broken.

2. Check whether the output and input resistances are normal
