The liquid level switch is an instrument used to detect the liquid level, and controls the on and off of the circuit through the liquid level. The following is an introduction to liquid level switches:
1. Types: Liquid level switches are divided into various types according to different principles and application scenarios. Including float type, electrode type, capacitive type, tuning fork type, etc. Different types of liquid level switches have their own unique characteristics and uses. 2.
Working principle: The working principle of the liquid level switch varies depending on the type. For example, the electrode-type liquid level switch uses the conductivity of water to determine the water level, while the float-type liquid level switch controls the opening and closing of the valve by lowering and raising the float due to the action of the liquid level. Capacitive liquid level switches use the change in capacitance between conductors to detect liquid level. When liquid fills the container, the capacitance between the electrodes changes. By detecting the change in capacitance, the liquid level switch can determine the presence of liquid and the level of the liquid.
3. Application scope: Liquid level switches are widely used in various occasions where liquid level detection is required, such as industrial production, chemical processing, water treatment, medical pharmaceuticals and other fields. In these places, liquid level switches can play an important monitoring and control role and help realize automated production. 4.
Advantages: As a common liquid level detection instrument, the liquid level switch has many advantages. First, it has high precision and sensitivity, and can accurately detect small changes in liquid level. Secondly, liquid level switches come in many different types and models, which can adapt to various application scenarios and needs. In addition, the liquid level switch also has the characteristics of high reliability and long life, and can operate stably for a long time.
In summary, liquid level switches play an important role in many industries and fields, providing reliable guarantee for automated production.
