    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.
