Built with advanced MEMS silicon micromachining technology and proprietary oil-filled dielectric isolation, this compact sensor delivers exceptional measurement accuracy and long-term reliability across a wide temperature range from -55°C to 150°C. With its ultra-small footprint (weighing only 13 grams) and multiple output signal options, the MPTW500 is the ideal choice for space-constrained environments requiring high performance and fast dynamic response.

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.
