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