Density Monitors for 400kv

This SF₆ Gas Density Monitoring System has been designed to allow the user a greater degree of flexibility for measurements and alarms than that currently provided by gauges with contacts. The system uses SF₆ density transducers which operate with a 6 to 20mA current loop technology for high noise immunity.
