In water heaters, temperature sensors are typically used to detect the temperature in the water tank and feed it back to the controller so that the controller can heat or keep warm according to the set temperature. The 10k temperature sensor probe is mainly used to detect the temperature of cold water in the water tank. In some water heaters, the 10k temperature sensor probe is also used to detect the temperature of hot water. The application scope of the 50k temperature sensor probe is more extensive. The principle of the temperature sensor for water heaters is based on the thermoelectric effect. It is usually made of metallic materials such as copper or platinum, and its resistance value changes with temperature.
The electric water heater wants to realize the precise control temperature, one of the essential conditions is the water NTC temperature sensor, which is usually set in the outlet to control the water temperature. Some intelligent electric hot water also set up an NTC temperature sensor at the inlet nozzle, which is connected to the circuit board, according to the principle of the circuit, when the water temperature changes, the voltage on both sides of the internal NTC thermiper resistance will also change, and the CPCP can obtain the exact temperature of the temperature by the voltage signal. In the process of the electric hot water, the constant temperature accuracy is generally required 2, which also requires the NTC thermistor to have high precision and sensitivity.
