- Page 11 ICP® accelerometers are internally amplified, two-wire accelerometers. Connections to the sensor require two leads: one for the power and signal, and the other for the common and signal return. Often, coaxial cables are used since only two conductors are needed. Coaxial cables are less expensive.

- Page 13 6.0 POWERING the system still does not operate properly, consult All ICP® sensors require constant current excitation an IMI Application Engineer. for proper operation. For this reason only use approved constant-current sources. A typical system Note: Always operate the accelerometer within the schematic is shown in Figure 11.
- Page 14 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.
- Page 15 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.
