FAQs

Differential switches are used to sense pressure differences between two points in a system, and actuate if a pre-defined difference is met. Across the hundreds of varieties of pressure switches, three things remain constant: a sensor (either bellows or diaphragm), a spring for determining the range set point and a snap-acting micro-switch.

When the pressure difference between the two ports becomes too great, the force on the diaphragm or bellows overpowers the tension set in the spring, causing an axial movement balancing arm or similar mechanism. This actuates the micro-switch which contains the electrical contacts.

The Applications Engineering differential switch range includes options for neutral and aggressive gases and liquids, to ensure the right stability for your application. These are ideal for;

  • Tracking chamber vacuum or overpressure
  • Monitoring and control of pressure-sensitive processes
  • Filter / level monitoring
  • Flow monitoring
