In order to facilitate the pressure sensor manufacture to test product quality, a kind of multi-channel pressure sensor testing system based on PCI8602 data acquisition card was designed. The system is composed of industrial computer, data acquisition card, standard pressure transmitter, signal processing circuit and multi-channel sensors, the VB developed application program control the entire testing process. By placing the 4~20 mA standard pressure transmitter and multi-channel pressure sensors in the same testing environment, the VB application program can monitor the quality of the sensors by analyzing the real-time data acquisition of every channel. The presented testing system could take advantage of VB language flexibility to adjust software function and testing interface. It can be widely applied in the pressure sensor lab testing for enterprise to save manual work, reduce labor intensity and improve the testing quality.
