The sensor is used in vibration monitoring and protection systems. The sensor is designed for employment in explosion proof zones of the premises and external installations  where flammable vapor and gas-air-mixtures, of the categories IIA, IIB, IIC, group T1-T5 may be formed.

The sensor is used for RMS Velocity (mm/s) / vibration acceleration (m/s2) measurements in one or three mutually perpendicular axes.

General data

  • Vibration RMS Velocity (mm/s) measurement;
  • Vibration Acceleration (m/s2) measurement;
  • Signal decomposition using the FFT method;
  • Data exchange due to interface RS-485 (Modbus RTU);
  • Current output signal 4-20 mA proportional to RMS Velocity;
  • Current output signal 10 ± 10 mA (non-standardized) proportional to peak Acceleration;
  • Output discrete signals (30 VDC, 100 mADC);
  • Status generation («Warning», «Alarm », «Normal»);
  • Field programmable set point & alarm levels;
  • Field programmable bode rate, address (RS-485);
  • Remote sensor calibration.
