Product Description

The GZP6812D is a compact digital pressure sensor with high accuracy and low current consumption, capable of measuring both pressure and temperature. An internal signal processor converts the output of the pressure and temperature sensor elements into 24-bit and 16-bit data, respectively. Each pressure sensor is individually calibrated and includes calibration coefficients. The coefficients are used in the application to convert measurement results into true pressure and temperature values. The sensor measurements and calibration coefficients are accessible via the serial I2C interface.

The GZP6812D pressure module features high integration, a compact size, and easy installation, facilitating system integration. It is widely used in applications such as vacuum pump, weather monitoring, and pneumatic control.

Function Description

This product is manufactured using advanced micro-electromechanical principles. Its core technologies are a MEMS pressure sensor chip based on the silicon piezoresistive effect and a high-performance signal conditioning AISC chip. The silicon micro-piezoresistive MEMS pressure sensor chip forms a Wheatstone bridge through four strain-sensitive resistors. The output signal is amplified, temperature-compensated, and linearized by the ASIC chip. The linearization and temperature compensation of the transfer function are implemented by the digital processing circuit in the ASIC. Through the polynomial compensation algorithm and multi-point pressure calibration technology at multiple temperatures, high-precision pressure measurement is achieved over the entire operating temperature range.
