The Performance Series differential pressure switches utilise a stainless steel diaphragm based sensor. This, when coupled with a precision stainless steel mechanism designed to minimise friction in the moving parts, helps deliver the market leading performance customers have come to expect from the series. The model 301 Differential Pressure Switch is suitable for setpoints between -12.5mbar and 15bar with maximum working pressures up to 110bar. Also available in models 303, 304 and 381 (EAC certification is available on request).
