DSL 205
Differential pressure switch for air, incl. set of hoses
Application
The DSL 205 is a differential pressure switch for monitoring over pressure, differential and negative pressure of air, gaseous, non-aggressive, non-flammable media in air ducts, supply or exhaust air units. For flow monitoring in electric heating coils as well as for V-belt and filter monitoring, as air pressure deficiency protection or as limit controller.
