Abstract

The invention provides calibration equipment and method of a pressure sensor. The calibration equipment comprises a temperature setting unit, a pressure setting unit, a control module and an environment detecting module, wherein the temperature setting unit is used for setting the temperature of a to-be-calibrated sensor; the pressure setting unit is used for setting the pressure of the to-be-calibrated sensor; the environment detecting module and the temperature setting unit are connected with the control module to detect and reflect the temperature parameter of the temperature setting unit in real time, and the environment detecting module and the pressure setting unit are connected with the control module to detect and reflect the pressure parameter of the pressure setting unit in realtime. By the calibration equipment and method, a calibration process is simplified, and calibration efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of sensor calibration, in particular to a calibration device and a calibration method for a pressure sensor. Background technique [0002] The calibration system of the universal pressure sensor is to provide a series of standard pressures by the dynamometer. For example, the standard weight series of the piston pressure gauge adds pressure to the sensor, and according to the output type of the AD circuit of the sensor, the corresponding value is read by the standard meter, and the input-output function relationship of the pressure sensor in the corresponding use environment is established. [0003] The calibration system of general pressure sensors has the following problems: [0004] ① Data acquisition is difficult. It needs to rely on manual observation and manual recording, and the consistency of reading data is poor; [0005] ②The process of calculating the calibration parameters is complicated. A l...
