There are many sensor products on the market. Perhaps the most common ones we remember are temperature sensors and pressure sensors. But in fact, according to the different requirements of the equipment itself, there are many other various sensors around us, including the water leakage sensor shown below, which is a representative one. As the name implies, when there is liquid leakage, they will give an alarm or automatically adjust to keep the liquid capacity of the equipment in a stable range. In addition, a water leakage sensor is used. Whether there is water can be seen through the electrode, so it has the characteristics of high sensitivity, convenient use, convenient installation, accurate measurement and reliable precision.

First, the working principle of water leakage sensor

The principle of water leakage sensor is to conduct electricity to liquid. Use electrodes to see if there is water, and then use sensors to convert it into dry contact transportation. Generally, it is open, but if you want to close it, you should book it in advance, usually for about three days. A main sensor can have several pairs, which is equivalent to having multiple water leakage sensors at the same time.

The water leakage sensor is completely sealed, which ensures the accuracy and reliability of the product, high sensitivity and convenient use and installation. The water leakage sensor can be regarded as a simple and easy-to-use facility, which can be installed alone or used with others. By inputting signals, the remote control of other devices can be completed.

Third, the leakage sensor manufacturer recommended

1, Zhangjiagang Taiheng Electronic Weighing Instrument Co., Ltd., established in 2006, is located in Zhangjiagang Economic and Technological Development Zone, near Suzhou, Wuxi, Shanghai and Nanjing, with convenient transportation. Is a company engaged in various electronic weighing instruments and automatic measurement control systems. Pocket scales were produced in the early days. Jewelry scale? ,? And kitchen scales and other products are of good quality and reasonable price? ,? So deeply supported and affirmed by customers at home and abroad? ; ? Products are exported at home and abroad? ,? Like what? :? America? ,? Europe? ,? Central and South America? ,? And southeast Asia. At the beginning of 2002, in order to expand the market, expand the product range and reduce the cost, we invested and built a factory in jiaomei Industrial Comprehensive Development Zone, covering an area of 8,000 square meters. The company has perfect production testing equipment and intelligent R&D talents.

2. Xinxiang Qidong Industrial Co., Ltd. was established in 1987. Is a professional manufacturer of research and development and production of automation instruments (mainly used with pressure vessels, boilers and other containers). The main products are liquid level meters (magnetic sensitive two-color type, magnetic column type, etc.). ) series, baking device joint control device series, pressure vessel quick-opening safety interlock protection device series, boiler alarm series. For more than 20 years, the company's products have sold well in China and exported to Russia, Mongolia and Southeast Asia, winning the trust and praise of the majority of users.

Qingdao Tairun Electronic Technology Co., Ltd. was incorporated in Qingdao Hi-tech Park in September 2003 with a registered capital of 654.38 million yuan. Is a high-tech enterprise specializing in the research and development and manufacture of magnetic sensors and intelligent instruments. The company has the core technology of "development and manufacturing of thin film magnetoresistive chips and magnetic sensors" and has a number of patents for magnetic sensors.

The water leakage sensor that we gave you an example above is quite representative in the market. They are suitable for liquid conduction. We use electrodes to observe whether there is water or other liquid. When necessary, through the automatic and intelligent control effect, the liquid in the equipment is kept in a stable capacity range, which ensures the accuracy and reliability of the product, and it is generally sealed, so the sensitivity is better, the use is more convenient and the installation is easy, so it is counted as one.
