High temperature pressure transducer MPT100

MPT100 High Temperature Pressure Transducer

The MPT100 series is an ultra-ruggedized, piezoresistive high temperature pressure transducer meticulously engineered to deliver continuous dynamic pressure measurements under severe thermal and physical strains. Designed utilizing state-of-the-art micromachined MEMS silicon technology, this miniature transducer provides an extraordinary natural frequency response up to 400 kHz while maintaining severe environmental survivability across a broad $-55^\circ\text{C}$ to $+150^\circ\text{C}$ operating envelope. Developed specifically for high-stress testing profiles, the MPT100 offers a premium, high-reliability solution for aerospace flight testing and wind tunnel research, serving as a seamless drop-in replacement for industry-standard Kulite pressure sensors
