A signal conditioner made for IEPE sensors is typically less expensive than those made for CHARGE sensors. IEPE can be used for force, pressure and acceleration sensors, as well as in measurement microphones. This output is collected on the electrodes sandwiched between the crystals and is then either routed directly to an external charge amplifier or converted to a low impedance voltage signal within the sensor. A built in IC chip amplifier converts the high impedance signal generated by the crystals to a low impedance voltage suitable for convenient coupling to readout instruments. A low impedance signal is advantageous because it can be transmitted across long cable lengths without a loss of signal quality. Table 1 lists the common signal conditioning needs for each measurement and sensor. [1][2][3] The supply or compliance voltage of the constant current source should be 24 to 30 V which is about two times the bias voltage. IEPE sensors are easier to use thanks to their integrated signal conversion and are less sensitive to electrical interference than piezoelectric sensors without IEPE. When force is applied to this sensor, the quartz crystals generate an electrostatic charge proportional to the input force. This may save up to 90 % power.
