Description

QKL-B4H pressure controller is a device used to maintain or control the pressure of a fluid (such as gas or liquid) within a desired range. It is commonly used in industrial and manufacturing processes where maintaining a constant pressure is critical to ensuring quality and consistency in the end product. The maximum pressure is up to 100 barG, with accuracy of 0.3% F.S. It is compatible with fluid gas or liquid. For pressure range in between up to 30 barG, we offer higher flow rate version, There are different types of pressure controllers, including mechanical, pneumatic, and electronic controllers. Mechanical controllers use a mechanical feedback mechanism to control the pressure, while pneumatic controllers use air pressure to adjust the pressure of the fluid. Electronic controllers use electronic feedback to adjust the pressure, and they can be more precise and flexible than mechanical or pneumatic controllers. Some common applications include controlling the pressure in pipelines, regulating the pressure of gases in a semi-conductor equipment such a MOCVD equipment, or maintaining the pressure in a pneumatic system. Electronic Pressure controllers are widely used in various industrial and scientific applications where precise control https://www.genndih.com/ https://youtu.be/HHO5-Tpo0-I
