IC Size

  1. The unit for data above is mm. The true position tolerance is not marked. The size tolerance is ±0.05mm.
  2. Connect B to the pipe on the bottom of the sensor, T to the top. The top pipe T is defined as high pressure connection.

Principle

This high-resolution differential pressure sensor with I2C communication is used to measure the difference in pressure across two points on a device. A high-performance MEMS pressure chip and a special conditioning chip are encapsulated inside the sensor. It will give you a comparative measurement between two points. Besides, the sensor IC adopts a unique multi-stage temperature-compensation algorithm to reduce the effect of environment on the output.
