Vibration velocity sensors with current output DVA121.3XX

Vibration velocity sensors with current output DVA121.3XX

Designed to measure the root mean square (RMS) value of vibration velocity in emergency protection systems (EPS);

Consist of a sealed housing, which is a piezoelectric acceleration sensor and conversion board;

Easily replace imported analogues;

Thanks to the version with connection terminal block inside the case (DVA121.352), the incoming cable is quickly and conveniently mounted;

For DVA121.352 - order available cable glands 3 types or nut;

Type of output signal – 4...20 mA
