High frequency dynamic pressure sensor MPTW800

MPTW800 high frequency dynamic pressure sensor

The MPTW800 series is an ultra-rugged, piezoresistive dynamic pressure sensor precision-engineered to capture fast-transient pressure fluctuations within volatile aerodynamic and thermodynamic testing environments. Utilizing advanced micromachined MEMS silicon cores shielded by an oil-filled media isolation capsule, this transducer delivers an extraordinary natural frequency response up to 400 kHz and maintains rigorous accuracy across an extended thermal profile from -55°C to +150°C. Developed specifically to fulfill strict B2B aerospace requirements, the MPTW800 series serves as a premium, seamless drop-in replacement for industry-standard Kulite pressure sensors in flight testing and wind tunnel research.

Key Features

• 400 kHz High-Frequency Bandwidth: Engineered with an unamplified, front-design pressure core that completely eliminates internal dead-volume resonance, allowing researchers to accurately monitor shockwaves, turbulent boundary layer interactions, and rapid acoustic transients in real time.

• Rugged Silicon-on-Silicon MEMS Construction: Features a fully active four-arm Wheatstone bridge dielectrically isolated sensor element welded to a stainless steel capsule body, ensuring minimal power consumption, zero outgassing, and outstanding long-term structural repeatability.

• Continuous 70 MPa Heavy-Duty Rating: Built inside a premium 316L or 17-4PH stainless steel housing capable of managing dynamic pressure cycles up to 70 MPa (10,152 PSI), guaranteeing ultimate explosion-proof containment and structural safety during severe testing profiles.

• Frictionless Kulite Cross-Reference Integration: Matches the precise mechanical threads, mounting interfaces, and millivolt/digitally-compensated signal outputs of heritage Kulite transducers, drastically lowering engineering redesign overhead and accelerating procurement cycles.
