YUNYI-2010 Series Electric Micro-pressure Source: High-stability Automatic Pressure Benchmark for Precision Micro Differential Pressure Instrument Calibration

Product Overview

In high-precision micro differential pressure measurement fields such as clean room differential pressure monitoring, HVAC air duct static pressure control, flue gas desulfurization and denitrification, pharmaceutical workshop differential pressure management, and semiconductor process gas flow control, the calibration accuracy and long-term stability of micro-pressure instruments are the core to ensuring reliable system operation. Traditional manual micro-pressure sources struggle to meet the demands of automated and highly repeatable calibration, while electric micro-pressure sources have become the ideal benchmark equipment for building high-precision digital pressure calibration systems thanks to stepper motor drive and digital control.

The Nexisense YUNYI-2010 series electric micro-pressure source is divided into two models: YUNYI-2010S (manual pressure control) and YUNYI-2010A (fully automatic pressure control). The fully automatic model uses a high-precision stepper motor to simulate manual cylinder movement, achieving stepless continuous pressure adjustment. It features a built-in high-precision pressure sensor and touch screen control system, supporting digital input to set target pressure. It can be widely used for precision calibration of micro (differential) pressure transmitters, micro-pressure sensors, micro-pressure diaphragm pressure gauges, and integration with fully automatic calibration systems.

The product has a compact structure and a user-friendly operation interface. It supports dual power supply solutions of AC220V/DC24V, with an operating temperature range of -30~80℃, meeting the dual requirements of laboratory standard environments and industrial on-site calibration.

Selection Guide and Integration Precautions

Selection Points:

1. Select the appropriate specification according to the maximum micro differential pressure range of the instrument under test, and it is recommended to reserve 20%~30% margin;

2. For projects requiring high repeatability and long-term stability, prioritize the YUNYI-2010A fully automatic pressure control mode;

3. When accuracy requirement is above 0.05%FS, it is recommended to use the 0.02%FS high-precision version;

4. For batch integration projects, contact Nexisense for OEM customization, including special pressure ranges, communication interfaces (RS485/Modbus, etc.), or enclosure protection level adaptation.

Integration Precautions:

• It is recommended to use clean and dry compressed air or nitrogen as the working medium to avoid oil mist and moisture affecting sensor accuracy;

• When integrating with automatic calibration systems, it is recommended to reserve sufficient pressure stabilization time (usually 30~60 seconds) to ensure data repeatability;

• The installation environment should avoid strong vibration and strong electromagnetic interference, and the operating temperature should be controlled within -30~80℃;

• After long-term use, regularly check the status of sealing components and perform zero-point calibration when necessary to maintain optimal performance.

Nexisense supports OEM/ODM customization and bulk supply, and can provide complete technical solutions according to the specific calibration procedures, system architecture, and on-site conditions of engineering companies.
