Voltage output accelerometer

Voltage output accelerometer another piezoelectric accelerometer output voltage signal rather than charge signal. This sensor is contained within the charge amplifier. Voltage mode sensor 3-wire (signal, ground, power) and 2-wire (signal / power, ground). 2-wire, also known as IC piezoelectric sensors (IEPE). Because you can easily use coaxial (2-wire, wire and shielded wire) connection, IEPE very popular. In this mode, the AC signal superimposed on the DC power supply. At the output terminal in series with a coupling capacitor to remove the DC bias voltage sensor, so that only access toCooling Temperature Sensorsignal output. Many modern instruments provide IEPE / ICP input interface, which can be directly connected IEPE sensors. If IEPE power supply interface is unavailable, you need a signal amplifier with a constant current source and an IEPE sensor used. 3-wire sensor requires a separate DC power cable supply. With charge output type acceleration sensor is different is that in addition to the piezoelectric ceramic element, the voltage output type acceleration sensor contains a tiny circuit, the circuit limits the operating temperature range of Crankcase Position Sensor's overall operating temperature range, usually no more than 125 ° C. There are also some design increased to 175 ° C, but its other properties will decline. Usable dynamic range - the piezoelectric ceramic element has a very wide dynamic range, charge output type acceleration Motor sensor on the scale is defined is very flexible because of its full-scale charge amplifier can be remotely adjusted freely by the user. The voltage output type acceleration sensor has established a full-scale, which depends on the internal charge amplifier, once produced by the plant will no longer be changed.
