The small float switch is a kind of liquid level control part with simple structure and convenient use. It has no complex circuit and will not be disturbed. It is often used for liquid level detection, remote transmission of on-site indication signals,liquid level alarm, etc. of various medium and small atmospheric and pressure liquid tanks. As long as the material is selected correctly, liquid, pressure and temperature of any nature can be used. A variety of installation methods are suitable for various types of containers, and can also be customized according to customer needs.

Liquid level sensor is an important industrial sensor, widely used in the measurement and control of liquids and gases. With the popularity of industrial automation, liquid level sensors have become an indispensable part of modern industrial production. In this article, we will introduce a commonly used level sensor - stainless steel level sensor.

I. Principle of operation

Stainless steel level sensor uses the conductivity of the liquid to measure the height of the liquid level. The sensor contains a resistive sensor and an electrode inside, when the electrode contacts the liquid, the liquid produces a voltage signal to the resistive sensor, the signal can be measured and recorded.

II. Features

Stainless steel liquid level sensor has the following features:

1. Strong corrosion resistance: stainless steel has good corrosion resistance and can resist the erosion of most corrosive liquids.

2. High accuracy: stainless steel level sensor adopts high precision resistance sensor, which can provide high precision level measurement results.

3. Good stability: stainless steel has good thermal and chemical stability, which can ensure the long-term stability of the sensor.

4. Easy to install and maintain: stainless steel has good high and low temperature resistance, can be used in high or low temperature environment, at the same time, stainless steel sensor structure is simple, easy to install and maintain.

Three, application areas

Stainless steel level sensors are widely used in petroleum, chemical, food, pharmaceutical, water treatment, beer manufacturing and other industries. For example, in the petroleum industry, the level sensor can be used to measure the oil level in the tank; in the chemical industry, the level sensor can be used to measure the height of the liquid in the reaction kettle; in the beer manufacturing, the level sensor can be used to measure the level of beer in the fermentation tank.

Fourth, the conclusion

Stainless steel level sensor is an important industrial sensor with strong corrosion resistance, high precision, good stability, easy to install and maintain. It has a wide range of applications in petroleum, chemical, food, pharmaceutical, water treatment, beer manufacturing and other industries. With the continuous development and progress of industrial automation, stainless steel level sensor will play a more important role in future industrial production.
