Data logger for a digital linear gauge

The steadily growing usage of integrated circuits, such as microcontrollers and microprocessors, results in major advances in digital signal processing.
Every sensor measures a physical quantity, which is most often converted into a representative electrical signal. Furthermore, the electrical signal can be digitized for an easy data transmission or post-processing.
The usage of data loggers in the digital metrology offers continuous and accurate measurement, storage and processing of information gained from electric or non-electric signals, respectively.
A data logger for the digital linear gauge DG-525 from the vendor Ono Sokki was realized. Subsequently, the measurement data was transmitted continuously by the data logger to the PC. The transmitted data was visualized in real-time via MATLAB.
By consideration of the measurement principle, various DG-525's characteristics (such as drifting of the zero point, hysteresis and linearity) were characterized by measurements. The static parameters that affect the measurements were analysed too.
