The mechanical differential pressure switch/differential pressure monitor PREMASREG DS-1 with metal angle, is used for monitoring above-atmospheric, differential and below-atmospheric pressure of clean air, gaseous, non-aggressive media in air ducts, air intake or exhaust devices. As a flow monitor, differential pressure governor, pressure controller for flow monitoring at electric heating registers as well as for monitoring V-belts and filters, as air pressure deficiency protection for monitoring ventilators, dampers, or as a limit value controller. Switchpoint adjustment is done internally using the internal precision scale.

These instruments are factory-calibrated. The DS-1 differential pressure sensor is supplied including the ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).

The mechanical differential pressure switch/differential pressure monitor PREMASREG DS-2 with 4-hole plastic base ring, is used for monitoring above-atmospheric, differential and below-atmospheric pressure of clean air, gaseous, non-aggressive media in air ducts, air intake or exhaust devices.

The DS-2 differential pressure sensor is supplied including the ASD-06 connection set (2 m connection hose, two pressure connection nipples, screws).

The pressure measuring transducer PREMASGARD SHD-SD measures relative pressures in the bar range. It converts the measurand into a standard signal of 0 - 10 V or 4...20 mA. Process connection is G 1/2" straight external pipe thread. SHD-LC is used for pressure measurement in gaseous and liquid media. Applications of this pressure transmitter are in hydraulics, pneumatics, process technology, in mechanical and plant engineering.
Not suitable for ammonia and freon.

The pressure sensor/differential pressure sensor PREMASGARD SHD 400 is used to measure above-atmospheric, below-atmospheric, and differential pressures in virtually neutral gaseous and liquid media. A rugged and non-sensitive ceramic pressure measuring cell is used. The measuring pressure acts on the ceramic membrane, causing it to deform. This membrane is fitted with a DMS bridge whose resistance value changes in proportion to the degree of deformation. The electronics integrated in the transmitter housing converts this change in resistance into a standard signal of 0-10 V or 4...20 mA. The process connection is implemented via two internal threads G 1/2". It is used in all areas of industrial of sanitary measurement technology, such as differential pressure measurement between the supply and return lines in heating systems or for monitoring filters, fans, and compressors.
