SGE-CWR06 Micro water density transmitter

Description:

It is used to control and monitor the density and moisture content of SF6 gas in sealed containers. It is applied to SF6 high-voltage circuit breaker, medium-voltage switch, gas insulated equipment (GIS), high-voltage cable, transformer and PT. It can digitally display (optional) the moisture content, pressure, temperature, P20, density, dew point and other parameters of SF6 gas in electrical equipment.And is provide with a communication interface, and that data of SF6 gas density, micro water, pressure, temperature, P20, dew point and the like are transmit to the background of the monitoring room through an RS485 communication mode, so that the reading of the SF6 density relay can be observed from time to time through the background.

  • Product Description

Main features:
