110kv GCB Density Monitors

110kv GCB Density Monitors

The main difference between density monitors and pressure gauges is that the density monitors will automatically adjust the reading for any changers in the pressure which are due to changes in temperature. Thus, the Density Monitor will always indicate the relative gas pressure at +20℃, regardless of the ambient temperature. The Density ...
