• FEATURES & BENEFITS

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

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 Performance Series differential pressure switches utilise a stainess 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 series.

• Ranges available up to 15 Bar (200 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
