Robust diaphragm pressure switching up to 10 bar
Variohm EuroSensor is launching a new range of robust diaphragm-type pressure switches aimed at demanding HVAC and industrial processes for air, water, hydraulic fluid and other oil mediums in measuring ranges from 0.3 to 10 bar. Available in a choice of brass (EPS01) or stainless steel (EPS02) housings, these competitively priced switches offer generous overpressure limits and a choice of NBR or Viton diaphragm materials for application flexibility.
These new EPS01 and EPS02 series pressure switches feature a G 1/8 pressure port as standard with other fastening thread options available for larger quantities. Designed for any mounting orientation, versions are available for single pole operation with NC or NO contacts in pressure ranges of 0.3 to 2 bar and 1 to 10 bar. The integrated micro switch is available with silver plated contacts as standard for the EPS01, and with silver or gold plated switches optionally available for the EPS02.
The media temperature range of -25 to +85degC and a switch point accuracy of under 10 per cent will suit a wide range of switching tasks whilst a mechanical life of over 1 million cycles and a switching frequency of 200/min helps to ensure more than satisfactory performance requirements. Both models also feature a maximum switching load of 2.0A (resistive), a 100VA breaking capacity and reference voltage of 42V. Electrical connection is via flat 6.3mm terminals. The slightly smaller, brass-housed EPS01 has a 17mm AF hexagonal fixing whilst the stainless steel EPS02 model has 19mm AF fixing.
The EPS01 and EPS02 are part of a universal family of pressure switches from Variohm EuroSensor. A third range, the EPS03, covers spring-loaded diaphragm or piston actuation with a micro switch switching element in a tough galvanised steel housing for pressure switching up to 350 bar.
