How does the electric contact water level gauge air-tightness and waterproof detection work?

2021/05/0620:50:09 home 307

The electric contact water level gauge is designed according to the different resistivity of water and steam to realize the water level detection and display. Simply put, the electrode of the electric contact water level gauge can conduct in water, but it will not conduct if there is no water. With the change of the water level, the change of the number of electrodes in the water can be converted into the change of resistance value, and then fed back or transmitted to the secondary instrument, so as to realize the functions of water level display, alarm, protection interlock and so on. , This type of electric contact water level meter is still widely used. It can be used for water level detection of soilless vegetable cultivation, etc., which is convenient for unmanned management. To achieve water level display, after all, it is an electronic product, and waterproofing is indispensable. So how do you know if the airtightness meets the requirements after waterproofing? That is to say, how is the air tightness and waterproof detection of the electric contact water level gauge done, and what is the operation process?

Electric contact water level gauge air tightness and waterproof detection On the test port;

2. Manually put the product to be tested into the mold, the upper and lower molds will contact and form a seal through the silicone seal between the two;

3. Open the suction switch, the electric contact water level gauge air tightness detection mold will be evacuated;

4. If the product is qualified, because the space in the mold is constant, there will be no gas entering the product, and the internal pressure value is constant; if the product has leaks, the gas in the mold space will enter the product, and the space will increase. The pressure drop means that the leakage value exceeds the standard, indicating that the product does not meet the sealing requirements and is unqualified;

5. Qualified products OK green light display, unqualified products NG red light display and buzzer alarm, and then you can take out the product, put in the next product to start the next product testing.
