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.
  • 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)
  • Weatherprrof IP66 enclosures in zinc alloy or stainless steel
  • ATEX and IECEx Ex d Flameproof models available
  • Environmentally and Hermetically sealed switch options
