MPTW100 High Frequency Pressure Sensor (Kulite Drop-In Equivalent)

The MPT100 series is a highly specialized, piezoresistive high frequency pressure sensor precision-engineered to capture dynamic pressure fluctuations in ultra-fast transient environments. Featuring an extraordinary natural frequency response up to 400 kHz, this transducer delivers absolute measurement accuracy across a broad operating temperature envelope from -55°C to +150°C and a pressure capacity scaling up to 70 MPa. Developed as a premium, direct replacement for industry-standard Kulite pressure sensors, the MPT100 series is optimized for non-intrusive deployment in aerospace flight testing and advanced wind tunnel research applications
