Images 3 STB Safety temperature cut out with capillary tube Variants Downloads Benefits ideal for heating and process industriesfor protection against exceeding the maximum temperatureno external power supplymanual reset Application 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. Description 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.
