The mechanical differential pressure switch / differential pressure monitor PREMASREG® DS-2 with 4-hole plastic base ring is used for monitoring above-atmospheric, differential and below-atmospheric pressures of air and other gaseous, non-aggressive non-combustible media in air ducts, air intake or exhaust devices, as 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 or limit value controller. Switchpoint adjustment is done internally at an inside precision scale. These instruments are factory-calibrated. The differential pressure switch PREMASREG® DS-2 is supplied including connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).
