PREMASREG DS 1
The mechanical differential pressure switch ⁄ differential pressure monitor PREMASREG
mospheric, differential, and below- atmospheric pressures of air and gaseous, non-aggressive media in air ducts, ventilation intake or exhaust devic-
es, as a flow monitor, as a 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 monitoring fans and air dampers, or as a limit value controller. The switchpoint is adjusted using
the internal precision scale. These instruments are factory-calibrated. The differential pressure switch DS 1 is supplied including connection set
ASD-06 (2 m connection hose, two pressure connection nipples, screws) and mounting angle DS - MW - Z.
