MPTW500 High-Performance Miniature Pressure Transducer for Demanding Applications
The MPTW500 Series miniature pressure sensor represents the pinnacle of Dabey’s pressure measurement technology. Engineered for applications where size, weight, and performance are critical, this transducer combines state-of-the-art MEMS silicon micromachining with robust stainless steel construction to deliver outstanding accuracy and reliability in the most challenging environments.
At the heart of the MPTW500 is a high-performance silicon sensing element fabricated using advanced micromachining processes. This MEMS chip is packaged in a proprietary oil-filled dielectric isolation system that protects the sensing element from harsh media while maintaining excellent thermal and pressure transmission characteristics. The result is a miniature pressure transducer that offers the performance typically found in much larger, more expensive sensors.
The all-stainless steel internal and external structural interfaces ensure compatibility with a wide range of measuring media, including corrosive liquids and gases. Whether you need to measure dynamic pressure in aerospace testing, monitor hydraulic systems in industrial automation, or validate engine performance in automotive applications, the MPTW500 delivers the precision and reliability you need.

Why Choose the MPTW500?
When you need accurate pressure data from a location too small for a standard sensor, the MPTW500 delivers. We’ve engineered this transducer to meet the same performance standards you’d expect from premium European and American brands — at a price point that keeps your project budget on track.
Every MPTW500 is individually calibrated and comes with a calibration certificate. We offer flexible customization options including special pressure ranges, custom threads, and modified output signals to match your exact requirements. And with typical lead times of 4-8 weeks for standard configurations, you won’t be waiting months to get your testing program underway.
Whether you’re an engineering firm looking for a reliable sensor partner or an OEM needing a custom solution, we work directly with you to get the right product for your application.
Many test‑programs face procurement delays from overseas miniature‑transducer suppliers. MPTW500 delivers equivalent test‑grade performance while shortening supply cycles for time‑sensitive R&D campaigns.

FAQ
Q1: Can MPTW500 serve as drop‑in replacement for Kulite miniature pressure transducers?
A: Yes. When configured with matching thread, output signal and pressure range, MPTW500 can reuse existing mounting bungs, wiring and DAQ set‑ups without fixture modification. It is widely selected as alternative for aerospace component validation projects troubled by long import‑product lead‑time.
Q2: How heavy is the MPTW500 exactly? Will it affect my wind‑tunnel model test results?
A: The sensor body weighs only 13 grams. This low mass is one of its main advantages for model‑mounted testing.
If you install multiple units on a small wind‑tunnel test piece, added mass still needs to be counted in your overall model weight budget. For ultra‑light micro‑model projects, share your model drawing with our engineers, we can discuss further installation suggestions.
Q3: I’m trying to replace Kulite sensors on my existing test stand. Can I reuse my existing wiring and mounting holes?
A: Mechanical and electrical compatibility depends on thread size, pressure range, output type and excitation voltage.
When ordering, specify your original Kulite part number. We configure thread, output and pressure span to match, so you can reuse existing mounting ports and DAQ wiring in most cases. Minor fixture modification may still be needed in a small number of old test‑setups. We do not guarantee 100% zero‑modification for every legacy installation.
Q4:What is the maximum temperature I can run this sensor continuously? Can it survive quick temperature shocks?
A: Compensated working range is ‑55 °C to +150 °C. This means measurement accuracy is guaranteed within this band.
Short‑term rapid temperature swings are acceptable for test‑cycle conditions. Do not keep it continuously running above 150 °C. Sustained over‑temperature will lead to permanent zero‑shift and damage the internal MEMS element.
Q5: Do you supply calibration certificates? Is the calibration traceable?
A: Every MPTW500 unit comes with our factory calibration report by default.
Our in‑house calibration follows internal standards. If your aerospace project requires third‑party traceable calibration documents, this is an optional extra service with additional lead‑time and cost. Please state this requirement clearly at quotation stage.
Q6: Can I get engineering samples for lab evaluation? How long will samples take?
A: Samples are available for genuine R&D and test‑program customers. Sample lead‑time depends on configuration. Standard stock‑range samples normally take 4‑6 weeks. Custom‑calibrated sample versions will need longer time. We do not provide free samples.
