The green wire and white wire are connected to the temperature sensor. Their function is to transmit real-time temperature to the motherboard and display board through the temperature sensor, so that we can know the current temperature and. the motherboard can receive and receive signals. The blue and red wires are connected to the water level sensor.
Quality judging criteria:
1. The main basis for judging the quality of the heat collecting part is the absorptivity, emissivity and heat transfer speed of the vacuum degree.
Traditional solar water heaters unilaterally emphasize heat collection performance and emissivity, while ignoring heat transfer speed. Therefore, the hot water in the vacuum tube cannot be quickly transferred to the water tank. so the temperature rises slowly. This is mainly a problem causedby unreasonable design.
2. Heat storage part.
There are three judging criteria: firstly, no leakage, secondly, thermal insulation and thirdly, large capacity. The key to avoiding leaks is whether the welding process and materials are corrosion resistant. Food grade stainless steel is generally used as the inner tank material in the market. The key to thermal insulation is the foaming process of the thermal insulation material and the thickness of the thermal insulation layer. The thermal insulation material must be fully expanded with imported polyurethane and undergo aging treatment. Only in this way can the cells be small and uniform. and the seamless thermal insulation layer.
Detailed information:
You can leaveboth aspects of the circuit and the material. Since the principle of triggering a small signal can effectively reduce the electromagnetic force on the ions, you can use the digital signal mode. In terms of materials, you can choose conductive silica gel as the protective body for stainless steel materials, which can prevent scale formation.
Try to use polypropylene and stainless steel materials resistant to high temperatures and corrosion entering the water tank, and use silicone rings to seal areas that need to be sealed . This sealing method is simple, easy to use. and very effective.

Green line and white line are 15K at 18K, the blue line and the red line are 60K. For the Siji Muge solar water heater, the sensorwater level is conductive when the water is full. When the green and white wires are at normal temperature, the resistance is between 15K and 18K. When the blue and red wire water level sensors are not. put into the water, the resistance is 60K, the transmitted temperature of the temperature sensor is actually the transmitted resistance value. Siji Muge Solar Technology Co., Ltd. is a high-tech enterprise in Beijing specializing in the production, application and development of solar thermal energy utilization technology products.
