DVA121.432 vibration velocity sensor with current output

DVA121.432 vibration velocity sensor with current output

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

It consists of a sealed housing, which is a acceleration sensor and conversion board. The amplifier is made in a separate connector housing;

Output signal type – 4...20 mA
