Delta Mobrey 207 Series Pressure Switch

Description

Delta Mobrey 207 Series Pressure Switch is suitable for setpoints between 0 and 1 bar absolute with maximum working pressures up to 3 bar. 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 unit is manufactured, checked and supplied in accordance with our published specification, and when installed and used in normal or prescribed applications, with the lid in place and within the parameters set for mechanical and electrical performance, will not cause danger or hazard to life or limb.

The model 207 incorporates a sealed reference vacuum for true absolute pressure sensing.

• Ranges available from 0 to 1 bar
• 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

Delta Mobrey 207 Series 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.
• Sealed reference vacuum for true absolute pressure sensing.
• Ranges available up to 1000 mbar absolute (760 torr). Static pressure up to 3 bar absolute (45 psia)

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
