Pyropress PERSEUS Pressure Switch

The Pyropress Perseus pressure switch (including differential and vacuum pressure) is another switch range innovation from our partner Pyropress. These industrial switches are suited to safety critical SIL2 applications and come with options for hazardous area certification in both intrinsically safe and explosion proof ATEX designs. These switches are manufactured from a high quality casting which offers robust construction and protection to IP67. One of the benefits of the Perseus range is the separation of the flameproof and adjustment chambers allowing adjustment of the set point with power on and the switch in operation.


Pyropress Perseus Pressure Switch ranges are split as follows….

  • Ultra low pressure switch range : 0.4 to 16 mBar
  • Low pressure switch range : 8 to 250 mBar
  • Medium pressure switch range : 0.1 Bar to 34 Bar
  • High pressure – Metal diaphragm switch range : 15 Bar to 420 Bar
  • High Pressure switch range : 4 to 800 Bar
  • Vacuum Pressure switch: -0.4 mBar to -950 mBar
