maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to ensure that liquids are not permitted

    Periodic recalibration may be required by plants with piezoelectric accelerometers. This method relies on strict certification and traceability requirements. It is a simple comparison to a previously calibrated always recommended that the user has the sensor accelerometer, typically referred to as a reference recalibrated periodically, particularly if the sensor standard, as shown in Figure 12.

    ICP® sensors are two-wire sensors. They are powered with a constant current DC source. The power supply is typically 18 to 30 volts DC current limited via a constant current between 2 and 20 mA. Typical battery operated supplies offer 2mA of constant current to extend battery life while Figure 14.
