Pressure Switch 230 Series Delta Mobrey

Designed in the mid-1970s and developed over subsequent years, the Performance Series switch range offers users the broadest range of options, the highest levels of set-point repeatability and the confidence of long term performance that a mature product such as this can prove. The model 230 Pressure Switch is suitable for setpoints between 0bar and 600bar with maximum working pressures up to 690bar.

The Performance Series pressure switches utilise bellows or bourdon tube type sensors that offer a very linear response to pressure change. These sensors, 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.

• Ranges available up to 600 Bar (8,500 psi)
• Weatherproof IP66 enclosures in zinc alloy or stainless steel
• ATEX and IECEx Ex d Flameproof models available
• Environmentally and Hermetically sealed switch options
• Set-point adjustable over the full range against a calibrated scale with tamperproof adjuster

Advantages:

1. 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

2. 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.

3. 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.

4. 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

Features:

• Precision stainless steel mechanism for arduous atmospheres and high humidity.
• Set point adjustable over the whole range against calibrated scale with tamperproof adjuster.
• Weatherproof and Flameproof models ATEX and IECEx.
• Safety vented design as standard.
• NACE MR-01-75 compatibility.
• Hermetically sealed microswitch option.
• Models for fixed switching differential, adjustable differential and HI-LO operation.
• Ranges available up to 600 bar (8,500 psi).
  Static Pressure up to 690 bar (10,000 psi).
