High-Precision Pressure Sensor Calibration

As pressure measurement technology continues to support increasingly demanding research, testing, and quality-control applications, Pressure Sensor Calibration is becoming an important part of reliable dynamic measurement. ZONEDE has developed the Pressure Sensor Calibration system based on the shock tube principle, providing a controlled approach for evaluating the dynamic response of pressure sensors.

The system is designed to calibrate key dynamic characteristics, including response time, rise time, and step-pressure plateau duration. By generating an ideal step-pressure wave through diaphragm rupture, the system can provide repeatable dynamic excitation signals for pressure sensor evaluation.

Precision Step Pressure for Dynamic Sensor Calibration

Unlike measurements focused only on stable pressure conditions, dynamic applications require sensors to respond accurately when pressure changes rapidly. The Pressure Sensor Calibration is designed around this requirement.

Its core positioning is based on the controlled rupture of a diaphragm to generate a step-pressure wave. This process provides a repeatable excitation signal that allows engineers and researchers to examine how quickly a pressure sensor responds to a sudden pressure change.

The system is intended for sensor R&D, quality inspection, and metrological calibration applications, offering a practical solution for laboratories and organizations that need to investigate dynamic sensor performance.

Designed for Flexible Calibration Requirements

The Pressure Sensor Calibration features a high-pressure section with a design pressure of ≥5 MPa, with nitrogen used as the working medium. Its step-pressure rise time reaches the microsecond level and can be customized, while the step-pressure plateau time is adjustable.

The system supports different diaphragm configurations to meet varying testing requirements. Its diaphragm options include aluminum alloy and polyester film, while the rupture method can use either a single diaphragm for differential pressure or a dual-diaphragm configuration for intermediate pressure relief.

Control is achieved through a remote-controlled gas injection and pressurization system, helping operators manage the pressure-generation process conveniently.

Broad Application Fields

The role of Pressure Sensor Calibration extends across multiple dynamic measurement scenarios. According to the system's application positioning, Pressure Sensor Calibration can be used for:

Testing and calibration of pressure sensor dynamic response times

Determination of rise times and step-pressure plateau durations

Verification of sensor performance under high-speed pressure environments

Pressure testing and calibration in aerospace, automotive safety, weaponry-related, and associated sectors

For different pressure sensors, the system can support a range of objects under test, including piezoresistive, piezoelectric, and strain-gauge-based pressure sensors.

Four Core Advantages

The Pressure Sensor Calibration is designed with several features aimed at improving calibration efficiency and repeatability.

High-Precision Step Excitation:

Microsecond-level rise time meets dynamic calibration requirements, while specialized sections help suppress reflected waves that could interfere with the sensor signal.

Precise Dual-Diaphragm Rupture:

The dual-diaphragm configuration enables precise control over rupture pressure and supports excellent repeatability. The adjustable plateau duration can also be adapted to the requirements of different sensors.

Safe and Convenient Operation:

Remote control of gas injection and high-pressure section translation helps simplify operation and supports a more convenient testing process.

Highly Customizable Configuration:

Pressure range, pipe section length, and other parameters can be customized according to specific testing requirements, allowing the calibration system to be configured for different laboratory applications.

With pressure sensors increasingly used in environments where pressure changes rapidly, understanding dynamic response characteristics is essential for dependable measurement. The  Pressure Sensor Calibration system combines controlled gas pressurization, step-pressure excitation, adjustable testing parameters, and flexible diaphragm configurations into one dedicated platform.

By focusing on response time, rise time, plateau duration, repeatability, and customization, the system provides laboratories, research institutes, and metrology organizations with a targeted solution for dynamic pressure sensor evaluation.

For organizations seeking a more controlled and repeatable approach to Pressure Sensor Calibration, the Pressure Sensor Calibration offers a focused platform built around precise step-pressure excitations.
