The Eltek Orbis IS Heat Detector A2S (234922) monitors the temperature by using a single thermistor network which provides a voltage output that is proportional to the external air temperature. The Orbis range incorporates several Heat Detector classes that suit a wide range of operating conditions.
Heat Detectors can be used for applications where Smoke Detectors are unsuitable and are ideal for environments that are dirty or smoky under normal conditions.
