Pyropress PERSEUS Temperature Switch

Pyropress Perseus temperature switch is a high quality robust housing switch and holds a single or dual microswitch option. This industrial switch is suited to safety critical SIL2 applications and come with options for hazardous area certification in both intrinsically safe and explosion proof ATEX designs.  It has been designed for use in environments where explosive gases can be present. In addition, 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 Temperature Switches are available in 2 variations

  • TF61 Rigid Stem Temperature Switch (TF62 with thermowell*)
  • TF615 & TF616 Capillary** Temperature Switch (TF625 & TF626 with thermowell*)

* A variety of standard thermowell pocket “U” lengths are available between 38 and 1200mm.

** Capillary lengths available up to 10m as standard.
