MPT800 Miniature Aerospace Pressure Sensor

The MPT800 series is a high-reliability, piezoresistive aerospace pressure sensor purpose-engineered for accurate dynamic pressure monitoring within severely constrained and aerodynamically volatile testing environments. Utilizing advanced micromachined MEMS silicon sensing elements protected by an oil-filled media isolation capsule, this transducer delivers an ultra-high natural frequency response up to 400 kHz and maintains stable measurement matrixes across an extended $-55^\circ\text{C}$ degree to $+150^\circ\text{C}$ thermal profile. Developed to serve as a direct, high-precision replacement for industry-standard Kulite pressure sensors, the MPT800 series provides a seamless mechanical and electrical drop-in solution optimized for aerospace flight testing and demanding wind tunnel research.
