Pyropress GUARDIAN Temperature Switch

The Pyropress Guardian temperature switch is an industrial switch suited to safety critical SIL2 and ATEX applications (Exia certification). It can be found in stem or capillary options. These switches are manufactured from either black anodised aluminium or 316 SS, both offering a robust construction and protection to IP66/IP67 certified housing. This combined with a variety of microswitches, mountings and sensor options has produced a switch range suitable for all weatherproof and intrinsically safe applications.


Pyropress Guardian Temperature Switches are available in 2 variations

  • T1100 Rigid Stem Temperature Switch (T1200 with thermowell)
  • T1700 Capillary* Temperature Switch (T1800 with thermowell)**

* Capillary length from 2 to 10 metres

** The T1800 supplied with a sliding gland, thermowells can be provided to suit individual applications
