System Control Robust Pressure Switches
Variohm Eurosensor has launched 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.
The 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, opines the company. The integrated micro switch is available with silver plated contacts as standard for the EPS01and with silver or gold plated switches optionally available for the EPS02.
According to the firm, the media temperature range of -25 to +85 °C and a switch point accuracy of under 10 % 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 2.0 A (resistive), a 100 VA breaking capacity and reference voltage of 42 V. Electrical connection is via flat 6.3 mm terminals. The slightly smaller, brass-housed EPS01 has a 17 mm AF hexagonal fixing whilst the stainless steel EPS02 model has 19 mm 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. The new pressure switches are part of a wide range of position, force, pressure, load, and temperature sensor technologies available from Variohm Eurosensor.
