Electrical Contact - Magnetic Type Pressure Industrial Gauge

ELECTRICAL CONTACT PRESSURE GAUGE

With external dome mounted snap action magnetic contacts are intended for the control and regulation of industrial processes where switching of electrical circuits are required for the industrial, mining and process industry.

  • 100, 160mm dial
  • S/steel case and bayonet bezel
  • 1/2" BSP /NPT Bottom or rear connection. Panel or surface mount flange optional
  • Magnetic snap action contacts
  • -100...0...250MPa, bar, psi etc.
  • Accuracy 1.0% F.S.

Service Intended

Suitable for media such as air, water, oil & gases that do not attack copper alloy or stainless steel parts or will obstruct the pressure system. Typical applications will be for the control and regulation of industrial processes where switching of electrical circuits are required. Externally adjustable, single or double contacts, can be fitted to a SA Gauge pressure gauge to make the gauge suitable to activate or deactivate electrical devices. Contact can make or break in an upward or downward pressure cycle.
