The MPT500 series is a high-precision, ultra-miniature piezoresistive silicon pressure transducer specifically engineered for demanding aerospace, dynamic airflow testing, and restricted-space industrial applications. Utilizing advanced micromachined MEMS silicon chips and specialized oil-filled media isolation, this rugged sensor captures rapid transient phenomena and shockwaves with an extraordinary frequency response up to 400 kHz. Designed as a seamless, high-reliability replacement for industry-standard legacy models like the Kulite HKM-17-500, the MPT500 eliminates sourcing bottlenecks by delivering uncompromised data stability with substantial cost-efficiency and shortened global lead times.
1. High accuracy you can count on
Accuracy up to 0.1% FS (best-fit straight line)
Fully welded stainless steel construction – tough and durable
Withstands 820g vibration and 950g shock; built for harsh environments
2. Wide temperature range, flexible options
Chip natural frequency ≥400 kHz – excellent dynamic response
Compensated temperature range options: -40°C ~ +125°C / -20°C ~ +80°C, etc.
Operating temperature up to 125°C – covers most industrial and test needs
3. Multiple outputs, easy to integrate
0-100 mV (4-wire, proportional or supply-independent)
0.5-4.5V (3-wire, digitally compensated, 8-32 VDC wide-range supply)
Low power consumption – great for remote or portable systems
4. Tiny footprint, flexible mounting
Weighs just 13g (excluding cable) – minimal load on your test setup
Thread options: M5×0.8 / 10-32 UNF
316L / 17-4PH stainless steel – compatible with many corrosive media
5. Great value, locally supported
Near-international-brand performance at a more competitive price for standard industrial applications
