Delta Controls Pressure Switch, 204/208/209 Delta Controls Pressure Switch, 204/208/209
The model 204 Pressure Switch is suitable for setpoints between psi: -14.5 (kPa: -100, bar: -1) and psi: 217.6 (kPa: 1,500, bar: 15), with maximum working pressures up to psi: 2,988 (kPa: 20,600, bar: 206). 

The model 208 Pressure Switch is suitable for setpoints between psi: -14.5 (kPa: -100, bar: -1) and psi: 217.6 (kPa: 1,500, bar: 15), with maximum working pressures limited by the flange rating. 

The model 209 Pressure Switch is suitable for setpoints between psi: -14.5 (kPa: -100, bar: -1) and psi: 217.6 (kPa: 1,500, bar: 15), with maximum working pressures up to psi: 290.1 (kPa: 2,000, bar: 20). 

The models 204/208/209 Performance Series 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.
