Mechanical pressure switches

Trafag pressure switches are used to control pressures by means of a on/off electrical switch.

Options

  • with/without display
  • various switching capabilities
  • CE, EX or Marine Approved

Sensing systems
Piston:

  • ideal for hydraulic systems
  • suitable for a high number of switching operations
  • resistant to abrupt pressure changes

Metal bellows:

  • sensitive pressure control of liquids, vapours and gases

Membrane:

  • measurement of liquids, vapours and gases
  • suitable for a high number of switching operations
  • resistant to abrupt pressure changes resistant to overpressure
