The PREMASREG® DS 1 mechanical differential pressure switch/differential pressure switch with metal bracket is suitable for monitoring overpressure, differential pressure and underpressure of clean air as well as gaseous, non-aggressive media in air ducts, supply or exhaust air devices.
The PREMASREG® DS-2 mechanical differential pressure switch/differential pressure switch with plastic four-hole base is suitable for monitoring overpressure, differential pressure and underpressure of clean air, gaseous, non-aggressive media in air ducts, supply or exhaust air devices. It is used as a flow monitor, pressure differential monitor, pressure monitor for flow monitoring in electric heating registers, as well as for V-belt and filter monitoring, as a low air pressure safety device, for monitoring fans, air dampers or as a limit value controller. The switching point is set on the internal precision scale. The devices are calibrated at the factory.
