Aerospace testing is one of the most demanding industrial environments in the world, requiring professional high-frequency dynamic pressure sensors to deliver accurate and repeatable test data. Extreme temperature swings, continuous mechanical vibration, and instantaneous pressure shocks place extremely high requirements on sensor stability, accuracy, and dynamic response. Ordinary industrial pressure sensors often fail to deliver reliable data under such harsh high-temperature aerospace testing conditions, leading to inaccurate test results and repeated experimental verification.
For engine bench testing, thermal cycle testing, and high-speed aerodynamic testing, engineers need dedicated high-frequency pressure sensors designed specifically for aerospace working conditions. This article introduces the MPTW100 high-temperature high-frequency pressure sensor, explaining its core performance advantages, applicable test scenarios, technical parameters, and selection guidelines for extreme aerospace environments.
1. Why Aerospace Testing Needs Dedicated High-Frequency Pressure Sensors
Unlike general industrial pressure measurement, aerospace testing focuses more on dynamic pressure changes rather than static pressure values. Engine combustion, airflow shock, and thermal expansion all produce transient pressure fluctuations that last only milliseconds.
Standard low-frequency sensors cannot capture these rapid changes, resulting in missing key test data. In addition, aerospace equipment operates across a wide temperature range from ultra-low temperatures at high altitudes to high heat near combustion structures. Only sensors with professional temperature compensation and anti-vibration design can maintain long-term measurement consistency throughout full-cycle testing.
2. MPTW100 Core Technical Features for Extreme Aerospace Conditions
The MPTW100 series is a high-frequency dynamic pressure sensor developed specifically for aerospace testing scenarios. It solves the common pain points of traditional sensors, such as temperature drift, slow response speed, and poor anti-interference performance.
- Wide temperature adaptability (-55°C to +150°C) Equipped with independent temperature compensation technology, the MPTW100 maintains stable accuracy even during rapid temperature cycling. It eliminates data drift caused by extreme temperature differences and adapts perfectly to high-altitude low-temperature environments and engine high-temperature test conditions.
- 400kHz high-frequency dynamic response Built with high-sensitivity piezoelectric chips, the sensor supports ultra-fast sampling and accurately captures transient pressure shocks, airflow fluctuations, and instantaneous pressure changes during engine startup and acceleration. It meets millisecond-level dynamic data collection standards for aerospace research.
- Micro lightweight integrated structure The compact miniaturized design fits narrow installation spaces on aerospace test benches and embedded component testing structures. The ultra-light structure avoids additional load interference on test equipment, which is critical for lightweight aerospace test upgrades.
- Strong vibration and impact resistance The 316L stainless steel housing and high-temperature resistant sealing structure allow the sensor to withstand 20g continuous vibration and periodic pressure impact. It runs stably in high-strength test environments and reduces frequent replacement and calibration costs.
- 0.1% FS high measurement accuracy With extremely low nonlinear error and excellent repeatability, the MPTW100 provides stable and credible pressure data support for aerospace performance verification, experimental analysis, and product iteration. It maintains accuracy within ±0.25% FS during drastic temperature fluctuations.
- 70MPa overload protection It effectively resists instantaneous pressure spikes in fuel pipelines and test systems, preventing sensor damage and test interruption caused by sudden pressure surges.
3. Compatibility & Calibration Standards
Data compatibility and test qualification are essential for aerospace sensor selection. The MPTW100 supports multiple mainstream signal outputs, including 4-20mA and 0-10V, which can be directly adapted to NI DAQ and most professional aerospace data acquisition systems without additional conversion modules.
For project audit and test certification requirements, all MPTW100 sensors support third-party professional metrology calibration. Complete calibration reports and qualification documents can be provided to meet the standard review requirements of aviation research institutions and industrial test projects worldwide.
4. Common Application Fields of MPTW100 Sensors
The MPTW100 high-frequency pressure sensor is widely used in multiple high-precision aerospace test scenarios:

5. How to Choose High-Temperature Aerospace Pressure Sensors
When selecting sensors for extreme aerospace test environments, three core indicators determine the overall test effect:
- Temperature compensation ability: Sensors without independent compensation are prone to data deviation under large temperature differences. MPTW100 controls accuracy within ±0.25% FS during extreme temperature changes, ensuring consistent test data.
- Dynamic response speed: For engine and airflow dynamic tests, high-frequency sampling is essential. The 10kHz response of MPTW100 ensures no missing transient pressure data.
- Environmental anti-interference performance: Aerospace test sites have strong vibration and electromagnetic interference. The optimized circuit and shock absorption structure of MPTW100 ensure stable signal output in complex environments.
Field troubleshooting tip for engineers: If waveform distortion or unstable pressure readings occur during dynamic testing, compare data collected at different sampling rates. Obvious changes in waveform peak or shape usually mean insufficient frequency response. For formal aerospace experiments, dynamic calibration before testing is strongly recommended.
