Technical datasheet

The D-Series pressure transmitters offer customers reliable and accurate solutions to their individual process requirements. This product has a wide range of process connections and is easily configurable via the D-Soft software. The D-Series can be used for a variety of applications when pressure, differential pressure, temperature, level or flow measurements are needed. The D21 Pressure Transmitter is suitable for measuring pressures from -1 to 1000bar with maximum working pressures up to 1200bar. It is intrinsically safe and flameproof, and ATEX and IECEx rated, giving users confidence in aggressive environments.

This robust pressure switch is suitable for a range of industrial applications, such as resistance to chemical attack or for use in corrosive atmospheres. The S30 Differential Pressure Switch is suitable for setpoints between -12.5mbar and 10bar with maximum working pressures up to 110 bar. This switch comes in models S31 and S34 (EAC certification is available on request).
Key Features
• Weatherproof and Flameproof models ATEX and NEC 500
• NACE MR-01-75 compatibility
• Ranges available up to 700 bar (10,000 psi) – Maximum working pressure up to 1000 bar (15,000 psi)
• Field set point adjustment against a reference scale
• Hermetically sealed microswitch options
• Optional gold alloy contacts
• Terminal block for easy field wiring
• Safety vented design as standard
• PED 2014/68/EU CAT IV option

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).
Key Features
