Chamber Over Temperature Protection

 How to set the bi-metal fail safe


Watch this video to learn how to set the primary over temperature fail safe on a thermal chamber. The chamber's primary fail safe is a bi-metal switch that protects the chamber from run-away or over temperature conditions. If an over temperature condition occurs, the bi-metal fail safe will trip and shut down the chamber's heating and cooling capabilities. It is factory set at 125°C and must be adjusted for the chamber to operate at temperatures above 125°C.

Additional fail safes are available to protect the devices being tested in the chamber. An Independent Fail Safe Module (IFM) or Precision Fail Safe (PFS) can be used as device protection for both over temperature and under temperature conditions.
