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 non-contact air gap (axial shift/clearance) measurements (air gap between sensitive surface and object (rotor pump).
General data
- Non-contact air gap measurement;
- Data exchange due to interface RS-485 (Modbus RTU);
- Current output signal 4-20 mA;
- 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);
