• Porvair indicators are designed and manufactured using proven robust design techniques to ensure resistance against the most severe of pressure and vibration environments.

  Indication can be by means of a visual or electrical output, or a combination of both variants. Visual indication is provided by means of a red coloured pop-up button that remains in the actuated position until manually reset. Electrical outputs can be provided by flying lead or a wide variety of standard and bespoke electrical connectors.

  Further to standard differential pressure indicators and dependent on specification requirements, Porvair can incorporate additional design features such as:

  Thermal lockout

  • Preventing false actuations during expected high viscosity pressure conditions such as cold system start-up.

  
  

  Non-reset mechanisms

  • Requiring removal of the DPI and a specific orientation in order to reset, preventing a fail-safe against.

  
  

  Surge damping

  • Providing resistance against false actuations during inadvertent system pressure spikes.
