Function of pressure controller
Pressure controllers can be used for neutral or corrosive gas and liquid media. The set value range is adjustable, with an adjustment range of 0.02~42Mpa.
The switching difference is not adjustable. The pressure controller includes a wide range and many varieties, including differential pressure controller,
explosion-proof pressure switch, explosion-proof differential pressure switch, pressure transmitter, differential pressure transmitter, wind pressure switch, and wind pressure transmitter.
The function of a pressure controller is to detect, display, alarm, and control signal output to ensure the normal operation of the system.
It collects and processes data through a high-speed MCU and has built-in precision sensors for compensation. It is a high-precision device
that detects pressure and liquid level signals, achieves pressure and liquid level monitoring and control. Widely used in
automation systems for measuring gas and liquid pressure in chemical, mechanical, hydrological, electrical, environmental, and other fields.
Due to its convenient and flexible adjustment, as well as simple installation, it can replace most situations where liquid level switches are used.
With the continuous development of technology, pressure controllers, as an emerging technological force, have occupied the pressure control
market and become a strategic requirement for the development of China”s industry. They are not only suitable for industrial petroleum and coal mines,
but also begin to appear in modern household appliances. It can be seen that pressure controllers are becoming increasingly important.
Pressure controller is mainly a type of pressure control product, which plays a role in timely controlling pressure and controlling the start and stop status of
equipment in industry, agriculture, and modern life. Take the familiar boiler as an example. A boiler is a relatively dangerous energy equipment.
Once its pressure is not controlled, the accident rate is very high. The pressure controller plays an irreplaceable role inside. When the boiler pressure
reaches the rated value, the pressure controller will control the boiler to stop working in a timely manner. When the pressure returns to the safe pressure value, the boiler will restart working.
