Differential Pressure Indicators (DPIs)

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.
