XGZP6891D is a prefect silicon pressure sensor offering a ratiometric digital data(I2C interface) for reading differential pressure over the specified full scale pressure span.

The XGZP6891D precision pressure sensor incorporates a silicon piezoresistive pressure sensor chip and an interior signalconditional Application Specific Integrated Circuit(ASIC) in a SOIC-16 package with two air vents, which can be mounted directly on a standard PCB.

The XGZP6891D is fully calibrated and temperature compensated for specified span, so XGZP6891D pressure sensor satisfy the perfect accuracry, which is designed for a wide range of application in medical care&health, home appliances, consumer electronic, industry, automotive, loT and other pneumatic devices etc by utilizing a microcontroller or microprocessor with D/A inputs.

Precision pressure sensor XGZP6891D is for high volume application at an affordable cost and perfect performance. Customized calibration parameter (e.g.pressure range etc.) are available. If measured media is rather than the dry gas or air, e.g.moist media, contact CFSensor for solution.

Using these sensors products may malfunction due to external interference and surges, therefore, please confirm the performance and quality in actual use. Just in case, please make a safety design on the device (fuse, circuit breaker, such as the installation of protection circuits, multiple devices, etc.), so it would not harm life, body, property, etc even a malfunction occurs. To prevent injuries and accidents, please be sure to observe the following items:

  • The driving current and voltage should be used below the rated value.
  • Please follow the terminal connection diagram for wiring. Especially for the reverse connection of the power supply, it will cause an accident due to circuit damage such as heat, smoke, fire, etc.
  • In order to ensure safety, especially for important uses, please be sure to consider double safety circuit configuration.
  • Do not apply pressure above the maximum applied pressure. In addition, please be careful not to mix foreign matter into the pressure medium. Otherwise, the sensor will be discarded, or the media will blew out and cause an accident.
  • Be careful when fixing the product and connecting the pressure inlet. Otherwise, accidents may occur due to sensor scattering and the blowing out of the media.
  • If the sensor come with sharp PIN, please be careful not to hurt your body when using it.
