DIFFERENTIAL PRESSURE SWITCH / DIFFERENTIAL PRESSURE CONTROLLER PREMASREG® DS
The PREMASREG® DS-2 mechanical differential pressure switch/monitor with 4-hole plastic base ring 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. It can serve as a flow monitor, differential pressure governor, pressure controller for flow monitoring of electric heating registers as well as monitor for V-belts and filters, as an air pressure deficiency protection monitor for ventilators, dampers, or as a limit value controller. Switchpoint adjustment is done using an internal precision scale. The device is factory-calibrated.
