Abstract:Paper introduced a virtual instrument testing system based on data acquisition equipment of Advantech USB-4704 and graphical programming software LabVIEW. The system achieved the real-time collection, processing and storage of voltage signal from the conditioning circuit of the Flexiforce Sensors A201, which can effectively measure the normal load in the Flexiforce Sensors A201. Test system is mainly composed of Flexiforce Sensors A201, the sensor conditioning circuit, USB-4704, application development software LabVIEW.
Key words:data acquisition card USB-4704;LabVIEW;data acquisition
