PRESSURE SWITCHES
Pressure Switch – Sentry Series
The Sentry family of switch products, comprising of PO1, PO2 and PO3, offers pressure ranges from -1 bar up to +1.5 bar and Pmax up to 15 bar. The one-piece enclosure offers exceptional build quality, across the range, as well as a reduction in the parts needed for manufacture, making it more economic to manufacture and better for the environment. (EAC certification is available on request). >>>Datasheet
201 Pressure Switch – Performance Series

Initially designed in the mid-70s and developed over subsequent years. the Performance Series range of pressure switches offers the broadest range of options, the highest levels of set-point repeatability all combined with the long-term performance and confidence of a well-established product.
Performance Series models 201/202/203/281 utilise a bellows type sensor that offers a very linear response to pressure change. This sensor, 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.
This range of pressure switches has been most successful in industries which may have corrosive atmospheres or need products that are resistant to chemical attack, such as the Oil and Gas, Chemical, Petrochemical, Power and Food.
The 201 Presure Switch is suitable for setpoints between -1bar and 75bar with maximum working pressures up to 100bar. Available in models 202, 203 and 281 (EAC certification is available on request).

204 Diaphragm Actuated Pressure Switch – Performance Series

As part of the Delta Mobrey Performance Series of pressure switches, the 204 model is a diaphragm actuated switch, working with a range of industries that may have corrosive atmospheres or need process instrumentation to be resistant to chemical attack.
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 Performance Series.
The 204 model, the diaphragm actuated switch is suitable for setpoints between -1bar and 15bar with maximum working pressures up to 206bar. Also available in the 208 and 209 models (EAC certification is available on request). >>> Datasheet
