Description

The Pyropress Guardian pressure switch (including differential pressure) is an industrial switch that can be adjusted for low and high pressure ranges. It features a wide selection of microswitches that can be fitted eg. single, dual, adjustable dead band and high current DC switching options. This switch is suited to safety critical SIL2 and ATEX applications (Exia option). Materials of construction include options in black anodised aluminum and 316 SS, making the Pyropress Guardian pressure switch very competitively priced, lightweight and durable product.

 

Pyropress Guardian Pressure Switch ranges are split as follows….

  • Ultra low pressure switch range : 2 to 55 mBar
  • Low pressure switch range : 8 to 250 mBar
  • Medium pressure switch range : 0.2 Bar to 19 Bar
  • Medium pressure switch range : 0.1 Bar to 34 Bar – Flush diaphragm/flange mounted version
  • High Pressure switch range : 1.5 to 640 Bar
