HL-C21C-P Application Field and Working Principle

Accessories

HL-C21C-P is designed for industrial space. This kind of pressure switch is mainly used to accurately monitor, control, and protect pressure system of liquid, gas, or steam. It can detect the pressure accurately, so it is widely used for pressure adjusting, circulation control, industrial compressed air control and equipment protection, in air conditioning and oil industry, in sanitary engineering and machine tools.

The working principle of this type pressure switch is not complicated. It uses an external power source, a set mechanical switch, and a sensing element. The sensing elements can be either a diaphragm or a bellows or a wide variety of other sensors. When the pressure around the sensing element changes, it can move a piston or a diaphragm, which in turn can actuate either a mechanical switch or an electrical contacts. When the pressure reaches an adjustable preset point, the switch will either open or close the circuit accordingly. It can also provide different output responses depending on the changes in pressure.

When it comes to the application field of HL-C21C-P, it\'s very versatile. This type of pressure switch is widely used in a variety of industries, such as oil and gas, air conditioning and heating, machine tools, automobiles, general instrument systems, environmental testing, liquid tanks or boilers and more. It is also often used for flow, temperature, level, and vacuum control systems. Some of its features include adjustable deadband, adjustable differential, long durability, extreme reliability under any environment, and high accuracy.

In conclusion, HL-C21C-P is considered a reliable pressure switch that offers excellent performance and great features that allow it to be used in a variety of industries. It can be used to accurately control pressure in liquid, gas or steam systems, while protecting them from any potential damage. Additionally, it also offers adjustable deadband and differential pressure, great reliability and durability, and highly accurate readings. There is no doubt that this type of pressure switch is a great tool to have in any industry.
