2-POLE FAILSAFE TEMPERATURE LIMITER, SAFETY SENSOR

1-POLE FAILSAFE TEMPERATURE LIMITER, SAFETY SENSOR

These safety devices automatically switch off the current in the controlled circuit as the temperature is reached, and switch it on again as the temperature falls below the set threshold value. The temperature of the controlled medium is thus maintained within a narrow zone. The limiter makes a last full annexation in case of mechanics injury.

Working temperature range: 0 – 350 °C
Areas of application:
– water heaters, hot water storage tanks
Trouble-free operation is conditioned by proper heat transfer between the controller’s sensor and the controlled medium.

3- AND 4-POLE FAILSAFE TEMPERATURE LIMITER MANUAL RESET

These devices automatically switch off the current in the controlled circuit as the pre-set temperature limit is reached, thus preventing overheating. Once the defection of the temperature regulation was repaired, and the device has cooled down to room-temperature, in voltage-free state, the limiter / protective guard can be re-started manually. Working temperature range: 0 – 350 °C Areas of application: - water heaters - hot water storage tanks. Trouble-free operation is conditioned by proper heat transfer between the protective limiter's sensor and the controlled medium. In case of capillary-damage or liquid-leakage, the device will cut the circuit one last time as positive safety-feature.

3-POLE TEMPERATURE LIMITER, PROTECTIVE GUARD

These devices automatically switch off the current in the controlled circuit as the pre-set temperature limit is reached, thus preventing overheating. Once the defection of the temperature regulation was repaired, in voltage-free state, the limiter / protective guard can be re-started manually. Working temperature range: 0- 355 °C Areas of application: - heat-storing stoves - saunas - large hot water storage tanks Trouble-free operation is conditioned by proper heat transfer between the protective limiter's sensor and the controlled medium.
