PREMASREG DS 2
The mechanical differential pressure switch ⁄ differential pressure monitor PREMASREG
above-atmospheric, differential and below-atmospheric pressures of clean air and other gaseous, non-aggressive non-combustible media in air ducts,
air intake or exhaust devices, 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 2 is supplied including connection set ASD-06 (2 m connection hose,
two pressure connection nipples, screws) and mounting ring DS -MR - K.
