Differential pressure switch / differential pressure controller PREMASREG® DS

Brand
€50.67
Tax included

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.
