204 Diaphragm Actuated Pressure Switch – Performance Series

Control applications needing a diaphragm operated switch

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

  • Precision stainless steel mechanism for arduous atmospheres and high humidity.
  • Set point adjustable over whole range against calibrated scale with tamperproof adjuster.
  • Weatherproof and Flameproof models ATEX and IECEx.
  • Safety vented or blow out device as standard.
  • NACE MR-01-75 compatibility.
  • Hermetically sealed microswitch option.
  • High Overload capacity (204).
  • Open diaphragm (208).
  • Hygiene connection (209).
  • Ranges available up to 15 bar (200 psi). Static Pressure up to 206 bar (3,000 psi).

 

FEATURES & BENEFITS

  • Better than 1% set-point repeatability
    Users can expect a set-point repeatability performance better than 1% on all configurations with some configurations being significantly better
  • Extensive range of options
    The Performance Series switches are available with an extensive range of materials, process connections, switch types, electrical entries, etc and offer customers many millions of different possible configurations.
  • More than 35 years experience in the field
    Installed in a wide range of applications from nuclear power plants to offshore oil rigs, the Performance Series’ long experience in the field offers customers the reassurance that they can be relied upon to survive the test of time in the harshest environments.
  • Safety
    All Performance Series models come with a safety vent to prevent the enclosure becoming pressurized in the event that the sensor is inadvertently damaged by excessive pressure
