The basic form of the sensor waterproof what

Sensor is very broad range of applications , in many electronic devices have applications above , there are also single use , the sensor in the course will encounter many problems, such as in wet and even underwater use , use in these environments will may use waterproof -type sensor , then the basic form of sensor waterproof everyone know .Many sensors , such as Engine Cooling Temperature Sensor, pressure sensors , etc., and even ultrasonic sensors are likely to use in a water environment, the market now there are two cases, one of the front-end waterproof A full waterproof type , waterproof front plug-in general , such as plug-in temperature sensor , pressure sensor, and screw , such that the front end can be inserted into the water -based waterproof effect, and the second half can not be sunk in the water , followed by the output signal place or a place where wiring is not water. Another is fully waterproof type, this general type are input , such as input type liquid level Engine Temperature Sensors, pressure sensors , etc., this type of sensor is completely waterproof sunk in the water are completely waterproof , but it kinds of prices are generally expensive , it is generally in front of customers are purchasing a ready- front waterproof type .
