1.Technical Principle and Core Components 

Pressure Sensing Technology 

Adopting high-precision pressure sensor, it can cover the measuring range from rough vacuum to high vacuum to ensure data accuracy. The sensor converts the physical pressure signal into an electrical signal, which is processed by a microprocessor and converted into a readable vacuum value.

Digital Display and Processing System 

is equipped with an LED or LCD digital display with a resolution of up to 0.1 Pa and an error range of ±1%. The screen supports multi-unit switching and can display real-time vacuum, working mode, running time and other parameters, so that the operator can intuitively monitor the status of the equipment.

Intelligent control module 

integrates microcontroller or PLC control system, which supports presetting parameters such as upper and lower limits of vacuum degree and timed working time. When the vacuum reaches the set value, the system automatically stops or switches modes; when the vacuum falls, the pump restarts to realize the function of vacuum pressure preservation.

Oil-free dry running technology 

adopts PTFE diaphragm pump or brushless motor design to avoid oil mist pollution and reduce maintenance cost, while ensuring low noise and long life operation, suitable for quiet environments such as laboratories.

2.Core Functional Features 

High-precision Real-time Measurement and Display 

• High resolution of digital display screen can accurately capture small changes in vacuum level and avoid human error in reading.

• Support backlight display, in the dark light environment can still clearly read the data.

• Some models are equipped with vacuum level trend graph to help users analyze the stability of the system.

Multi-mode Intelligent Control 

• Zone Mode: set the upper and lower vacuum limits, and the pump starts and stops automatically within the zone, suitable for vacuum preservation, pumping of closed containers and other scenarios.

• Timing mode: preset working time, automatic shutdown when expiration, suitable for batch experiment or long time running task.

• Limit mode: set a single vacuum target value, the pump continues to run until it reaches the target and then stops, suitable for rapid vacuuming needs.

• Manual Mode: Supports the user to manually adjust the pump speed or vacuum level to meet special experimental needs.

Low noise and energy-saving design 

• adopts brushless permanent magnet motor or diaphragm pump technology to reduce mechanical friction and noise.

• Intelligent sleep function: when the vacuum level is stable and no adjustment is needed, the pump automatically enters the low-power mode to save energy.

Safety protection and data logging 

• Overload protection: when the current or vacuum level is abnormal, the system automatically stops and alarms.

• Anti-backflow design: Built-in solenoid valve or check valve to prevent gas backflow from polluting the system.

• Data recording function: some models support USB interface or wireless module, which can export historical data to computer or cell phone for easy analysis.

3.Summary of Product Advantages 

• Accurate and Reliable: High-precision sensor combined with digital display screen ensures real and traceable data.

• Intelligent and Convenient: Multi-mode automatic control reduces manual intervention and improves operation efficiency.

• Safe and durable: oil-free dry design, overload protection and anti-reflux function, prolonging the life of the equipment.

• Widely applicable: covering the needs of laboratory, industry, medical and other fields, and supporting the development of customized functions.
