In the heating power industry, the indoor temperature of heater needs to be measured in real time to adjust the temperature and the flow of supply and return water, wherein a temperature detection device is a very important ring for temperature acquisition and directly influences the heat supply quality of heater.
Because the temperature detection device for heater comprises the switching power supply, the communication module (4G, NB and the like) and the temperature probe, in the working state, the heat generated by the switching power supply and the communication module can influence the detection value of the indoor temperature of heater, which is detected by the temperature probe. The temperature detected by the existing temperature detection device can be 1.5 to 5 degrees higher than the indoor temperature, and even higher. The background is needed for temperature compensation, which is caused by the change of the environmental temperature, and the compensation effect is not ideal.
