• 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
   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

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.

Unlike other models from the Performance Series the model 204 couples a diaphragm type sensor to a precision stainless steel mechanism to enable very low setpoints to be achieved but with high static pressures

• 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
• Set-point adjustable over the full range against a calibrated scale with tamperproof adjuster
