PSRT series piezoresistive ceramic pressure transducer
The PSRT piezoresistive monolithic ceramic pressure sensors are specifically optimized for battery-powered applications like smart water metering. Featuring a digital I2C output, <2 mA current consumption, and MCU sleep mode support, they ensure an operational lifetime of over 10 years.
Integrated ASIC electronics handle internal pressure and temperature calibration, delivering precise offset and span corrections. Crucially, a specialized mechanical design minimizes assembly stress, completely eliminating the need for post-installation zero-point calibration and significantly streamlining your manufacturing process.
Fully EMC-compliant, the sensors offer exceptional long-term stability, include an EEPROM for traceability, and utilize Al2O3 ceramic for excellent resistance to aggressive media.
