Electrical Gauges

Listing ID #3496003

The SE model contact pressure with electrical alarm contacts are suitable for controlling or regulating process sequences. The contact opens and closes electrical circuits in relation to the position of the pointer on the pressure gauge.Our contact pressure gauges with bourdon tube system are used at process pressures of approximately 1kgcm2 and upwards. The materials used make the gauges suitable for chemically aggressive gases or liquids,although these may not be too viscous or be susceptible to crystallization. The inexpensive tried and tested bourdon tube system coupled with modern modular principle provides a very reliable yet inexpensive contact pressure gauge. Electrical alarm contact are used as magnetic snap-action contacts,especially in harsh industrial conditions. The high contact pressure and the choice of different electrical contact materials enable high currents to be switched reliably. If the electrical switching spaces of the alarm contacts are exceeded or not reached (See DE 12 31), a relay is to be used to provide an appropriated current rating (DE 12 30). Inductive alarm contacts operate without physical contact and thus have no unfavorable effects on the pressure measuring system while having an unlimited service life. A control unit is always needed to operate these contacts. Contact pressure gauges with inductive alarm contact can be used in potentially explosive atmospheres,provided that the appropriate regulations are complied with.
