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 Crankshaft Sensor , so that only access to the sensor signal 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 Crankshaft Sensor Replacement 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 the 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 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.
