Each MEMS Wheatstone bridge is laser-trimmed at wafer level for ±0.05% initial matching. Combined with a 24-bit ΔΣ ADC, this delivers 17-bit ENOB at 100 SPS.
Factory calibration at 11 pressure points and 7 temperature points. NIST-traceable reference standards. Calibration coefficients stored in onboard EEPROM — plug and measure.
Programmable IIR/FIR filter stages. Selectable oversampling ratios from 1× to 4096×. Built-in 50/60 Hz notch filter eliminates power-line interference without external components.
Industrial pressure transmitters and transducers for hydraulic, pneumatic, and process automation systems. 4-20 mA loop-compatible with external driver.
Refrigerant pressure monitoring in heat pumps and chillers. Differential pressure for filter monitoring and airflow measurement in building management systems.
Low-pressure sensing for ventilators, CPAP machines, and infusion pumps. High-resolution differential mode for spirometry and respiratory monitoring.
