HAOBANG HI-TECH HBP1402D701AL8-4

The HBP1402D-4 is an absolute pressure digital pressure sensor featuring high accuracy, low power consumption, wide operating temperature range, and dual measurement functions for both pressure and temperature. The outputs of the pressure and temperature sensor elements are converted to 24-bit and 16-bit data respectively via an internal signal processing unit. Each unit is individually calibrated, with calibration coefficients stored in the on-chip memory. Offset, sensitivity, temperature drift, and nonlinearity compensation can all be corrected using these calibration coefficients. In actual applications, the coefficients are used to convert measurement results into true pressure and temperature values. Sensor measurements and calibration coefficients are accessible via the serial I2C interface. The HBP1402D-4 is housed in an LGA8 package with a compact form factor, facilitating easy mounting and system integration. This product is widely used in industrial control, vacuum systems, and instrumentation applications.
