8XH Series High Accuracy Pressure Sensors
The 8XH series pressure sensor integrates a MEMS die, an ASIC chip and passive components within an isolated oil cavity. Leveraging the MEMS die bridge resistance for both temperature and pressure measuring in the same oil temperature environment, it can provide the accurate on-site temperature signal required for compensation, achieve outstanding initial accuracy and excellent EMC performance.
Gas transmission, industrial transmitters, and fluid control manufacturers demand high-accuracy, reliable pressure sensors that enable system-level precision without field calibration. Many existing solutions require post-installation trimming, lack integrated temperature compensation, or offer insufficient media compatibility for aggressive process environments. The 8XH series includes 82H, 85H, 85FH and 86H models, and each can provide pressure and temperature dual output in digital output mode.
The 8XH Advantage
- Eliminate field calibration: ±0.3% span total error band (TEB) for system-level precision.
- Real-time compensation: simultaneous 24-bit pressure and temperature data enables accurate gas volume correction in EVCs.
- Direct digital integration: I2C output feeds seamlessly into MCUs for wireless IoT-enabled transmitters.
- Harsh media compatibility: 316L stainless steel withstands corrosive process gases and aggressive chemicals.
- Long-term reliability: ±0.1% span/year typical stability reduces maintenance costs.
