Digital Vibration Sensor GP 2


The sensor was designed to be used in vibration monitoring and protection systems at the power stations, oil pumping stations, gas compressor stations, and other industrial objects. The sensor can be installed into explosive areas of the premises and external installations, where flammable vapor and gas-air-mixtures of the categories IIA, IIB, IIC of the groups T1-T5, could be formed.

The sensor detects a measurement of the air gap (axial shift) between face of the sensitive part of the sensor and object surface (rotor shaft).


  • Axial shift measurement – air gap between the face of the sensitive part of the sensor and object surface (face of the rotor shaft)
  • Data exchange via RS-485 (Modbus RTU protocol)
  • Output of the signal as a unified current at 4-20 mA
  • Comparison of the measured parameter to the limit setpoints, stored in the non-volatile memory of the sensor
  • Generation of statuses (Warning and Failure) and generation of discrete signals to the external devices in case of exceeding the set limits (sensor-relay)
  • Remote configuration of the parameters: network address, communication speed, warning and failure setpoints; remote calibration of the measured channel


  • Housing material – nickel-coated steel
  • Explosion protection type – explosion-proof shell
