XY-2001A Micro Pressure Gas Source: Stable Pressure Reference for High-Precision Micro Differential Pressure Calibration

In the field of process industrial automation, micro differential pressure measurement is widely used in clean room environmental monitoring, HVAC systems, combustion air flow control, flue gas desulfurization and denitrification, pharmaceutical and semiconductor processes. The calibration accuracy requirements for micro (differential) pressure transmitters, micro pressure sensors, and micro pressure diaphragm gauges are increasingly stringent. Traditional pressure sources struggle to provide sufficiently small pressure change steps and long-term stability.

Product Overview

The Nexisense XY-2001A micro pressure gas source (micro pressure gas generator) is specially designed to solve this pain point. It is made of high-quality stainless steel and aluminum alloy, combined with German imported seals and connectors, and can provide a stable, controllable micro pressure reference with sufficiently small changes. It is one of the core devices for building high-precision digital pressure calibration systems.

The product has dimensions of 280mm×210mm×150mm and weighs only 2.6kg, making it suitable for fixed installation in laboratories or portable use on site. It supports multiple pressure range configurations including (-50～0～50)kPa, (-60～0～200)kPa, (-90～0～600)kPa, and (±1)kPa. The minimum controllable adjustment reaches 1Pa, which can meet the calibration needs of micro pressure instruments with 0.05 grade and higher accuracy.

Technical Features

• Simple operation and convenient maintenance, suitable for long-term continuous use;

• Stable pressure rise and fall with minimal influence from external temperature;

• High minimum controllable adjustment fineness (1Pa) and excellent pressure stability;

• Excellent sealing performance, close to zero leakage.

These features make the XY-2001A perform excellently in calibration scenarios that require maintaining a micro pressure reference for a long time, especially for the precision calibration of micro differential pressure transmitters, micro pressure sensors, and micro pressure diaphragm gauges.

Application Scenarios

The XY-2001A micro pressure gas source is widely used in the following engineering fields:

• Clean rooms and HVAC systems: Periodic calibration and installation debugging of micro differential pressure transmitters and micro pressure sensors;

• Environmental protection and energy industry: Calibration of micro pressure instruments in flue gas desulfurization and denitrification, combustion air flow control;

• Pharmaceutical and semiconductor: Calibration of micro pressure measurement instruments in high-cleanliness process environments;

• Metrology verification institutions: Standard traceability and comparison of micro pressure instruments in laboratories;

• System integration projects: Integrated with multi-channel automatic pressure calibration systems, PLC or SCADA systems to build fully automatic micro pressure calibration workstations.

For system integrators, this pressure source can be used as a standardized micro pressure reference module, directly connected to existing digital pressure calibration platforms, significantly improving the overall accuracy and stability of the system.

Selection Guide and Integration Considerations

Selection Points:

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

2. For precision calibration projects requiring 1Pa-level fine adjustment, priority should be given to the standard XY-2001A model;

3. For batch integration projects, contact Nexisense for OEM customization, including special pressure ranges, interface specifications or communication protocol adaptation;

4. When used with Nexisense or other brands of intelligent digital pressure calibrators, it is recommended to use standard quick connectors to ensure reliable connection sealing.

Integration Considerations:

• The working medium is recommended to use clean compressed air or nitrogen to avoid oil contamination affecting micro pressure accuracy;

• Installation environment temperature should be controlled at 0~40℃, relative humidity not exceeding 80%, avoiding strong magnetic fields and corrosive gases;

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

• After long-term use, regularly check the sealing components and replace German imported sealing components if necessary.

Nexisense supports OEM/ODM customization and bulk supply, and can provide personalized solutions according to the specific calibration procedures, interface requirements and system architecture of engineering companies or integrators to help projects land quickly.
