Virtual instrument based measurement system for analysis of static and dynamic characteristics of temperature transducers

The present work shows the structure of a measurement system dedicated to examine static and dynamic characteristics of sensors used to measure temperature. The measurement system was built on the basis of a set of signal conditioners connected with a data acquisition card built in a PC. The data acquisition was completed with the use of a virtual measurement device developed in the LabVIEW environment. A heated circulating bath was used as the source of reference temperature. During the experiments, the sensors were submersed in water of given temperature with the use of a computer controlled arm. The article also presents the results of the calibration procedure which was carried out, as well as selected application schemes.
