DELTA-comb, Model 702.03.100 (see data sheet PM 07.19)
• Differential pressure transmitter DELTA-trans,
Model 891.34.2189 (see data sheet PM 07.18)These differential pressure switches are particularly intended for the monitoring of differential pressures in filter systems, pumps and pipeline systems in the heating, climatic and ventilating technology sector, technical building equipment and in the water management industry.
The differential pressure ranges of 0 ... 250 mbar up to 0 ... 25 bar provide ranges, which are required in most applications. The sturdy and compact design of the differential pressure switchDELTA-switch makes it possible to use it even under tough industrial ambient conditions.
The adjustment of the switchpoint is made by setpoint screws accessible from the front. The assistant scale enables a relatively accurate adjustment of the switchpoints over 270 p ° and indicates the setpoint that is momentarily adjusted.
