Digital pressure controllers are smart devices used to detect and control pressure parameters. They are widely used in various fields such as petroleum, chemical engineering, metallurgy, electric power, and water supply for measuring and controlling the gauge pressure and absolute pressure of various gases and liquids.

Among numerous pressure controllers, the “Digital Pressure Controller” produced by Xi’an Yuny Instrument integrates multiple functions such as measurement, display, output, and control. It features stable performance and durability, making it a favorite among equipment manufacturers across various industries. Today, let’s take an in-depth look at Yuny Instrument’s “Digital Pressure Controller”!

YK-331 Digital Pressure Controller

The YK-331 series pressure transmitter and controller uses pressure sensors imported from the United States and is controlled by an intelligent microcontroller. It is a highly integrated product that combines pressure measurement, display, analog transmission output, and alarm output. The YK-331 series digital pressure controller features high measurement accuracy, a compact structure, comprehensive functions, and an attractive appearance. It is suitable for industrial automation control, petrochemical, municipal engineering, building automation, and mechanical equipment applications.

Product Highlights

01. Imported core
This controller uses an imported pressure sensor from the United States, which is responsible for converting pressure signals into electrical signals for transmission and processing. It is shock and vibration resistant with an accuracy error of 0.5% and a wide measurement range of 0 to 100 MPa. With an intelligent microcontroller as the control core, it provides more accurate measurements, fast core processing speed, and precise real-time pressure feedback.

02. Measurement + Display + Output + Control
The YK-331 series pressure transmitter and controller integrates pressure measurement, display, analog signal transmission output, alarm output, and control functions into one unit, making it widely applicable in industrial automation, process control, environmental monitoring, and other fields. While accurately measuring gauge pressure, it can display setpoints, alarm statuses, and other information in real time. It supports 4-20mA and relay signal outputs, as well as RS485 and relay signal outputs, enabling remote monitoring and control in various industrial automation systems.

03. Axial or radial installation options
The YK-331 series digital pressure controllers support axial or radial installation to meet the diverse on-site requirements of different customers. Axial installation ensures seamless integration of the digital pressure controller with the system while providing stable measurement and control performance. Radial installation reduces interference from system fluids on measurement results, resulting in more accurate measurements. Both installation methods offer customers more flexible and efficient solutions. However, it is important to note that vertical installation is mandatory when the measurement range is less than 100 kPa.

04. Hydraulic/Water Pressure/Air Pressure/Oil Pressure The YK-331 series digital pressure controller measures pressure through sensors and converts the measurement results into digital signals, thereby achieving precise pressure control. Through upper and lower pressure control, it realizes automatic pressure start and stop, featuring high precision, compact structure, comprehensive functions, and an attractive appearance. It has a wide range of applications in various pressure media such as hydraulic, water pressure, air pressure, and oil pressure.

In the field of industrial automation, digital pressure controllers are becoming increasingly widespread. The YK-331 digital pressure controller has replaced traditional mechanical pressure controllers primarily due to its outstanding intelligence, convenient adjustment methods, intuitive display effects, excellent accuracy, reliable stability, and long service life. It is widely used in industrial automation control, petrochemical municipal engineering, building automation mechanical equipment, and other applications.
