Aneroid Barometer Verification Device: High-Precision Automatic Atmospheric Pressure Calibration System

Nexisense Aneroid Barometer Verification Device is a dedicated calibration platform developed specifically for meteorological, aviation, and laboratory atmospheric pressure metrology. The device uses an imported high-precision resonant pressure sensor to achieve 0.02-grade high-precision measurement. The 10.4-inch capacitive touchscreen combined with the Windows operating system provides an intuitive operation interface and powerful expansion capabilities, allowing flexible addition of functional modules according to different verification regulations. The high-precision barometer can display key information such as atmospheric pressure, altitude, and temperature in real time, providing reliable technical support for metering verification institutions and system integrators in the construction of high-precision atmospheric pressure standard devices.

Product Overview

The core of the device is a high-precision resonant pressure sensor that can accurately capture atmospheric pressure changes with a resolution of 0.01 hPa. The 10.4-inch capacitive touchscreen interface is user-friendly, supporting precise control of lifting/lowering rates, automatic altitude conversion, and switching between multiple engineering units. The data acquisition interval defaults to 0.5 seconds and supports real-time storage and Excel export. The system fully complies with national meteorological instrument verification regulations and is suitable for periodic verification, type evaluation, and standard traceability of aneroid barometers, barometric altimeters, and related meteorological instruments.

In actual engineering projects, the device can be directly integrated into automatic verification software systems to achieve closed-loop operation from pressure establishment to report generation, significantly reducing manual intervention and meeting the needs of batch verification and remote monitoring.

Core Functions

The lifting/lowering rate control function is in hPa/min units and can precisely set the pressurization/depressurization rate according to verification regulations, ensuring a standardized and highly repeatable verification process. The current altitude display is automatically calculated based on real-time atmospheric pressure and the altimeter formula, providing accurate altitude information, especially suitable for aviation instrument calibration.

Unit switching supports multiple engineering units such as kPa, Pa, hPa, mbar, inHg, and mmHg, with hPa as default, facilitating data comparison under different standards. The data acquisition and storage function defaults to once every 0.5 seconds, displaying and saving historical records in real time for subsequent analysis. The setting function allows users to calibrate the sensor and set airport altitude to adapt to verification needs in different altitude environments.

The curve saving function allows one-click saving of the current pressure change curve to the desktop “Pictures” folder, supporting report preparation. The timing function records the verification process time; click “Timing” to start, click “Pause” to end and reset, meeting the requirements of regulations for verification duration.

Data storage and export operations are simple: click “Data” to enter view mode and stop real-time updates; click “Download List” to export data as an Excel file, automatically saved to the computer desktop “Downloads” folder, enabling data traceability and report generation.

Selection Guide and Integration Notes

Selection Key Points

1. Select the appropriate configuration according to the actual verification instrument range and test chamber space; it is recommended to reserve some margin to accommodate instruments of different sizes.

2. For occasions with extremely high precision requirements, prioritize the 0.02-grade sensor version.

3. Projects requiring remote data management or extended communication are recommended to be configured with USB interface and Windows system.

4. For batch verification projects, contact Nexisense for OEM customization, including test chamber size adjustment, unit switching optimization, or development of specific functional modules.

Integration Notes

• The installation environment temperature should be controlled within -10℃～40℃, avoiding strong electromagnetic interference and severe vibration.

• Before use, the sensor zero point must be confirmed and calibrated to ensure measurement accuracy.

• When exporting data, use the standard USB interface; it is recommended to reserve sufficient storage space on the computer desktop.

• Regularly check the sealing performance of the test chamber to prevent external atmospheric pressure fluctuations from affecting internal measurement results.

• After long-term use, it is recommended to perform sensor traceability calibration once a year to maintain optimal performance.
