A split system heat pump's defrost sensor is used to detect ice buildup on the heat pump's outdoor coil. When ice builds up on the coil, it reduces the heat pump's ability to transfer heat, which can ...

Why heat flux (flow) is an important thermal parameter. How researchers have developed an innovative heat-flux sensor. Details on the performance of this sensor in flat and curved situations. We know ...

In this fire alarm circuit, a thermistor works as the heat sensor. When temperature increases, its resistance decreases, and vice versa. At normal temperature, the resistance of the Thermistor (TH1) ...
