Highlights and Applications: ME 500 Pressure Sensor
The ME500 Pressure Sensor is designed for accurate pressure measurement in demanding environments where media compatibility, abrasion resistance, and long-term stability matter. Its flush diaphragm design supports direct exposure to the process medium, helping minimise issues linked to clogged ports or dead volumes.
With multiple nominal pressure ranges from 0.5 bar to 800 bar, and support for gauge, absolute, and sealed gauge configurations (range-dependent), the ME500 fits a wide variety of industrial pressure measurement requirements. The sensor delivers a mV/V differential output from a piezoresistive Wheatstone bridge, making it well suited for integration into OEM assemblies and transmitter designs.
Its ceramic Al₂O₃ diaphragm provides strong resistance against many aggressive substances, often removing the need for extra protective coatings. Thermal compensation and ceramic-based linearity help maintain dependable performance over temperature and across the measurement range.
