Utilizing UHF couplers and sensors, partial discharge signals are detected and carried to a master control unit where a filtering process is applied to reject interference. The amplitude and frequency of the UHF partial discharge pulses are digitized, analyzed and processed in order to generate an appropriate partial discharge data output, supervisory control and data acquisition ( SCADA ) alarm.
Rugged Monitoring provide a range of wideband partial discharge sensors for detecting partial discharge activity in the insulation of medium voltage and high voltage.

The compressor discharge temperature protection is triggered when the temperature sensor on the discharge tube of the compressor reads too high of a value. The cause of this can be a faulty sensor, a faulty board, or an actual fault in the refrigerant lines ( blockage, kink, etc.). Verify code appears after resetting power to the system.
Noncontact discharge measurement by means of radar technology for open rivers. The RQ30 is a sensor for continuous discharge measurement of rivers, open channels and canals with known crosssection profile. The sensor uses innovative radar technology to measure velocity, water level and discharge.
