Pyropress ARGUS Temperature Switch

The Pyropress ARGUS 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 PPS (engineering polymer) or high quality investment cast 316 SS, both offering a robust construction and protection to IP66/IP67 for use within heavily polluted industrial and marine environments. In addition, thermowells can be provided to suit individual applications.


Pyropress Argus Temperature Switches are available in 2 variations

  • TS520 Rigid Stem Temperature Switch (TS510 with thermowell)
  • TS570 Capillary* Temperature Switch (TS570 with thermowell)**

* 316 SS armoured capillary from 2 to 10 metres

** The T570 supplied with a sliding gland, thermowells can be provided to suit individual applications
