MPTW250 Wide-Temperature High-Precision Aviation Pressure Transducer

MPTW250 aviation pressure transducer delivers stable, fast pressure measurement. It works reliably under extreme cold, high heat, strong vibration and heavy shock. We support full custom specs for aerospace, automotive and all industrial testing projects.

Specifically, we develop the MPTW250 series pressure transducer for strict aerospace and industrial test conditions. It adopts mature MEMS sensing chips and isolated oil filling technology to keep long-term measurement stability.

Furthermore, we build the whole shell with stainless steel. The solid structure holds up to 20g sine vibration and 50g half-sine shock. It fits well in aircraft, engine test benches and heavy industrial equipment.

Meanwhile, this transducer covers a wide working temperature from -55℃ to 150℃. Buyers can pick matching temperature compensation grades to cut data drift during temperature changes.

In addition, it carries 10 kHz circuit bandwidth. The quick signal response meets all dynamic pressure test needs for aviation aerodynamic experiments. We offer two standard accuracy levels to fit different test standards.

For easy on-site installation, we supply diverse power supply modes and electrical output signals. Customers can also swap pressure thread ports and aviation connectors freely.

Therefore, the MPTW250 transducer becomes a reliable pressure test solution for global aerospace, petrochemical, shipbuilding and machinery clients. We provide full customization to match special equipment parameters.
