The DMP 331P pressure sensor is specifically designed for measuring the pressure of high temperature air, which makes it ideal for use in aerospace component test rigs. With its ability to accurately measure air pressure up to 300°C and 20 bar gauge, this sensor provides vital data for ensuring the reliability and safety of critical aircraft components.
Consider the testing of a pneumatic valve intended for use in an engine bleed air system. This valve controls the flow of high-pressure, high-temperature air bled from the engine compressor, and its reliable operation is critical for various aircraft functions. During testing, the DMP 331P is integrated into the test rig to precisely monitor the air pressure at both the valve inlet and outlet. This provides engineers with essential data on the valve’s performance, response times, and leak integrity, ensuring it meets the stringent demands of flight.
Another application where the DMP 331P proves invaluable is in the testing of heat exchangers for environmental control systems (ECS). These heat exchangers regulate cabin temperature by facilitating heat transfer between the high-temperature bleed air and cooler air. To guarantee passenger comfort and safety, these components must undergo rigorous testing under extreme temperatures. The DMP 331P‘s high-temperature capability allows it to accurately monitor the pressure of the air flowing through the heat exchanger during these tests, providing insights into its performance and structural integrity.
Furthermore, the DMP 331P is employed in the testing of sensors and probes designed for high-temperature environments. For example, temperature sensors used in exhaust gas temperature (EGT) measurement systems require calibration and testing under extreme conditions to ensure accuracy. The DMP 331P enables precise control and monitoring of the pressure of the high-temperature air used in these calibration and test setups, guaranteeing the reliability of critical engine data.
The DMP 331P‘s robust construction, featuring a stainless steel 316L diaphragm and process connection, ensures durability and resistance to corrosion, even when exposed to high temperatures and aggressive media. An integrated 300°C high-temperature protection device further enhances its suitability for demanding aerospace applications. The 4-20mA output signal and DIN43650A plug connector allow for seamless integration into existing monitoring and data acquisition systems, providing real-time pressure data for analysis and control.
