Pressure sensor temperature compensation system

The utility model discloses a temperature compensation system of a pressure sensor, which is characterized in that a temperature measuring chip and a pressure measuring chip are arranged in a pressuresensitive device, and the temperature measuring chip is very close to the pressure measuring chip; the signal conditioning circuit comprises a microprocessor, a memory, a digital-to-analog conversionchip and a programmable gain amplifier. The temperature measuring chip is arranged in the pressure sensitive core, the temperature of the pressure chip is accurately measured, a specific compensationvalue is inquired through the temperature, zero output and sensitivity are adjusted, and multi-point accurate temperature compensation is achieved. According to the pressure sensor, the measurement precision of the pressure sensor can be improved so as to meet the use requirements of high-precision application occasions, and finally, the influence caused by the difference between pressure sensitive device individuals can b
