Detectors suitable for special environments such as nuclear power, thermal power plant, petrochemical plant.

The WR-EX1 thermal sensor uses a special material that allows the external conductor to expand or contract in the longitudinal direction due to ambient temperature changes. The WR-EX1 thermal sensor uses the principle of turning on and off the contacts built in the sensor. If the ambient temperature rises above a certain temperature (nominal operating temperature), the external conductor of the detector is enlarged, the built-in contacts are short-circuited and fire signals are emitted and the LED of the detector body is lit to indicate a fire. When the temperature is reduced, the outer conductor of the sensor contracts and the built-in contact drops
