SOR Dual Hi-Lo Pressure Switch
Dual Hi-Lo pressure switches are rugged, field-mounted instruments. 

The pressure sensing assemblies are conventional Static "O" Ring type. The main difference is that two sensing assemblies share a common process pressure port, housing and electrical conduit connection. 

Two discrete sensing assemblies provide independently adjustable, fine resolution Set Points that can be calibrated to the same actuation point, or split to the full span of the adjustable range without interaction.
