Differential pressure switch / differential pressure controller PREMASREG® DS

The mechanical PREMASREG® DS 1 differential pressure switch/monitor with metal bracket serves to monitor above-atmospheric, differential and below-atmospheric pressure of clean air as well as gaseous, non-aggressive media in air ducts, air intake or exhaust devices. It is used as a flow monitor, differential pressure governor, pressure controller for flow monitoring at electric heating registers or for monitoring V-belts and filters. Further applications are found in air pressure deficiency protection, fan or air damper monitoring and limit value control. The switchpoint can be adjusted by means of an internal precision scale.
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.
