Diaphragm pressure switch RT112

differentialSPDTthreaded

RT pressure switches incorporate a pressure controlled, single-pole change over swich where the contact position depends on the pressure in the connection port and the set value. The RT series consists of pressure switches, di€erential pressure switches and pressure switches for neutral zone regulation, all for general use within the industrial and marine segments. The series also covers safety pressure switches dedicated for steam boiler plants. For installations in which operation is particularly critical from safety and economic points of view, the use of fail-safe pressure switches is recommended. The use of gold-plated contacts is also recommended in such installations, provided operation involves only a few switching cycles or signal currents and voltages.
