201 Pressure Switch – Performance Series

Bellows Actuated for high performance on control style applications

Initially designed in the mid-70s and developed over subsequent years. the Performance Series range of pressure switches offers the broadest range of options, the highest levels of set-point repeatability all combined with the long-term performance and confidence of a well-established product.

Performance Series models 201/202/203/281 utilize a bellows type sensor that offers a very linear response to pressure change.  This sensor, 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.

This range of pressure switches has been most successful in industries which may have corrosive atmospheres or need products that are resistant to chemical attack, such as the Oil and Gas, Chemical, Petrochemical, Power and Food.

The 201 Presure Switch is suitable for setpoints between -1bar and 75bar with maximum working pressures up to 100bar. Available in models 202, 203 and 281 (EAC certification is available on request).

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.
  • Models for fixed switching differential, adjustable differential and HI-LO operation.
  • Precise and accurate operation guaranteed by use of hydraulic formed bellows, or capsule stack.

 

FEATURES & BENEFITS

  • Better than 0.5% set-point repeatability
    Users can expect a set-point repeatability performance better than 0.5% on all configurations with some configurations being significantly better
  • 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.
  • 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.
  • 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.
