Differential pressure switch / differential pressure controller PREMASREG®
The mechanical differential pressure switch/ differential pressure monitor PREMASREG® DS 1 with metal angle, is used for monitoring above-atmospheric, differential and below-atmospheric pressure of clean air, gaseous, non-aggressive media in air ducts, air intake or exhaust devices. As a flow monitor, differential pressure governor, pressure controller for flow monitoring at electric heating registers as well as for monitoring V-belts and filters, as air pressure deficiency protection for monitoring ventilators, dampers, or as a limit value controller. Switchpoint adjustment is done internally using the internal precision scale.
These instruments are factory-calibrated. The DS 1 differential pressure sensor is supplied including the ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).
