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 386 Performance Series differential pressure switches utilise a nitrile 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 4 Bar (60 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
