ME 782 Pressure Sensor Piezoresistive Flush Membrane with signal conditioning

Introducing ME 782 Pressure Sensors – the pinnacle of precision and durability! Built with a ceramic base plate and flush diaphragm using the piezoresistive principle, these sensors feature a Wheatstone bridge on the ceramic, integrated signal conditioning electronics for I2C output, and electronic calibration through the onboard ASIC, available in bar or psi. The electronics provide offset and span correction, while the Zero Correction software compensates for offset shifts during assembly. With EMC compliance, patented design, and EEPROM for traceability and custom calibration, ME 782 sensors excel in handling aggressive media. Trust in ME 782 for unrivalled precision and long-term stability in pressure sensing.
