Product data sheet DSA: Pressure switch How energy efficiency is improved Control and monitoring according to needs and with no auxiliary energy. For regulating and monitoring pressure in liquids, gases and vapours Especially suitable for applications in compact installations Upper switching point can be set Fixed switching difference, no hysteresis setting is necessary Sealable Pressure sensor made of brass for non-aggressive media Technical data Power supply 400 mA, 24 V, 10 VA Minimum load with gold-plated contacts Maximum load with silver-plated con- 10(4) A, 250 V~, 50 W, 250 V= tacts Maximum load with gold-plated contacts1) Minimum load with silver-plated con- 100 mA, 24 V tacts 3 2 Pressure connection Admissible sensor temperature Admissible ambient temperature Pipe and wall mounting Transparent cover Ambient conditions Housing material Impact-proof thermoplastic Housing-mounted plug Standard plug with female cable connector for cable of Ø 6...10 mm Standards and directives Protection class Machine directive 2006/42/EC (according to appendix IIB) Overview of types Type Setting range Switching difference Maximum pressure Admissible vacuum loading DSA: Pressure sensor made of brass for non-aggressive media; Xs = upper switching point If the contacts are subjected to a load greater than specified, the gold plating will be destroyed. They are then classed merely as silver contacts and lose the properties of gold-plated contacts Depending on the fitting position, see the fitting instructions. The devices are not suitable for outdoor applications. Excluded from the directive on pressure equipment 97/23/EC (as per Art. 1.3.6) Right of amendment reserved © 2014 Fr. Sau
