ME 772 Flush Diaphragm, Piezoresistive Ceramic Pressure Transducer with signal conditioning

Introducing ME 772 Pressure Sensors – the epitome of precision and stability. These sensors feature a ceramic base body, flush diaphragm, and operate using the piezoresistive principle. The Wheatstone bridge, screen-printed on the ceramic diaphragm, faces an interior cavity. Signal conditioning electronics generate a non-ratiometric output of 0 to 10 V. Pressure and temperature calibration are electronically performed with the on-board ASIC, offering versatility in bar (ME772) or psi (MEP772). Constant aging detection ensures long-term stability, and the ME 772 family meets EMC requirements. The ASIC stores production-specific data, allowing custom calibration. With excellent chemical immunity, these sensors are suitable for aggressive media use. Trust ME 772 for unmatched precision and reliability in challenging applications.
