DVA121.3XX vibration velocity sensors with current output

DVA121.3XX vibration velocity sensors with current output

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 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;

Output signal type – 4-20 mA;


RPE "TIK" developed alternative DVA141.2XX vibration sensors, made in a smaller case and with a MIL connector:

  • To replace the DVA121.342 vibration sensor with the DVA141.214, you will need to replace the mating connector - 2-pin instead of 4;
  • DVA121.352 and DVA141.252 vibration sensors are complete analogs, connected via a terminal block.
