Most households now have all kinds of water heaters installed, common ones are gas water heaters, gas electric water heaters, electric water heaters, natural gas water heaters, etc. This will make it more convenient and faster for everyone to use hot water.
The temperature sensor refers to a sensor that can sense the temperature and convert it into an available output signal. When the water temperature reaches a certain set temperature, the power supply of the heating tube is cut off through the control circuit. But if your water heater does not have a temperature sensor, then the electric water heater will keep heating, and it will continue to burn when it is boiled. This is a very dangerous thing.
The Features of Water Heater Temperature Sensor
- Easy and convenient installation, the size can be customized according to the installation structure.
- The resistance value and B value have high precision, good consistency, and stable performance.
- good resistance performance of water-and-moisture, terminal docking, and high accuracy in measuring temperature.

The Working Principle of Water Heater Temperature Sensor
Cold water enters the water heater and flows through the water-air linkage valve body. Under the action of a certain pressure difference of the flowing water, the water-air linkage valve is pushed, and at the same time, the micro switch of the DC power supply is pushed to turn on the power and start the pulse igniter. Open the gas transmission electromagnetic valve, and continue to automatically re-ignite through the pulse igniter until the ignition is successful and enters the normal working state.
The Application of Water Heater Temperature Sensor
Water heater, shower room, rapid hot water faucet
