PREMASREG DS 2
The mechanical differential pressure switch ⁄ differential pressure monitor PREMASREG
monitoring above-atmospheric, differential and below- atmospheric pressures of clean air and other gaseous, non-aggressive non-combus-
tible media in air ducts, air intake or exhaust devices, as pressure difference detector or pressure monitor for flow detection 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.
