A pressure sensor automatic test system is designed for measurement of multi-channel sensors and multiple parameters.A multi-function matrix switch circuit is designed with a high-precision data collector to achieve function of switch and measurement;using Lab VIEW design upper computer software to achieve function of display and calculation and report of calibration data
temperature compensation data
time drift data.Experiment shows that the system can measure parameters such as bridge voltage
resistance and current of 90 pressure sensors
and meet detection and verification needs for mass production of pressure sensor with precision of 1%
