Pyropress ARGUS Pressure Switch

The Pyropress ARGUS pressure switch (including differential and vacuum pressure) features a unique switchcase option injection moulded from PPS engineering polymer. They have been ATEX & IECEx certified suitable for CAT 1 CE Ex and safety critical SIL2 applications. Materials of construction include options in PPS and 316 SS (wetted and non wetted parts) making the Pyropress Argus pressure switch very competitively priced, lightweight and durable product.


Pyropress Argus Pressure Switch ranges are split as follows….

  • Ultra low pressure switch range : 2 to 38 mBar
  • Low pressure switch range : 8 to 250 mBar
  • Medium pressure switch range : 0.2 Bar to 22 Bar
  • Medium pressure switch range : 0.1 Bar to 22 Bar – Flush diaphragm/flange mounted version
  • High Pressure switch range : 0.8 to 800 Bar
  • Vacuum Pressure switch range: -995 mBar to -2 mBar
