What is the role of the waterproof vent in the temperature sensor

Temperature sensors are devices that detect and measure heat and cold and convert them into electrical signals. Mainly include thermistors, thermocouples, etc.

Primarily to help monitor industrial heating and cooling systems and control smart thermostats, thermocouples provide feedback to boiler control systems in homes. In automobiles, our NTC thermistors measure air and gas temperature in a miniature, lightweight design, saving space in small systems.

 In domestic stoves and appliances, our platinum resistance temperature sensors help cooks prepare a perfect meal. In microwave ovens, our thermopile sensors measure temperature without contacting the food. In order to measure the accurate value of the temperature sensor, if water vapor enters the temperature sensor, the value will be inaccurate. So its waterproof is very important, we have to add waterproof vents in the measurement part. The waterproof and breathable membrane material is adopted, and the double-layer optical coating treatment of AR (anti-reflection) and AF (anti-fingerprint) is carried out. Even if the water vapor enters the temperature sensor, the water will not be immersed inside the temperature sensor. It not only protects the electronic components from being damaged, but also can clearly see the value of the temperature sensor.
