The mechanical differential pressure switch/differential pressure monitor PREMASREG~ DS2 with plastic mounting base is suitable for monitoring over-, under- and differential pressures of air, gaseous non-aggressive, non-flammable media in air ducts, working and venting devices. For flow monitoring at electric heating elements, as well as for string breakage detection, filter monitoring and air pressure error protection, for monitoring fans, air dampers or as a limit value controller. Setting the switching points is done with the inside setting scale. The switches are factory set. The differential pressure switch PREMASREG~ DS2 includes connection set ASD-06 (2 m connection hose, two connection nipples, screws).
