PCS-200 displacement probe / Random DC shifting and changes in amplitude values

[Rene Velasquez]

It has been observed that a failure of the PCS-200 sensor could cause random variation in the DC component and amplitude value of a vibration signal.

In these cases, the solution is to replace the sensor.
The measurement chain components and the symptoms of the failure are shown in the attached file.

One might suspect a failure in the LIN conditioning module or the input card in the ZPU-5000. However, the problem has been determined to be the sensor.
