There are many application areas for safety temperature cut outs in the heating and process industries. In conventional oil-fired or gas-fired boilers, these devices are used to monitor the boiler water. The safety temperature cut outs feature a manual reset button which must be actuated for unlocking.

If the temperature at the probe increases, the measuring liquid in the measuring system expands. If the temperature exceeds a critical value, the device triggers, the voltage-free contact switches and the system is set to a defined safe state. When the temperature has decreased by approx. 15 K, the device can be unlocked and the system resumes operation.
