Abstract A multichannel temperature measurement system based on LabVIEW
and modular instruments with general purpose input/output interface is described.
External simple electronic components, such as analog switches arrays, sampling
resistors and voltage reference are used to expand the analog input channel of the
instrument. The interface circuit for 3-wire resistance temperature device powered
by the voltage reference was designed and constructed. The feasibility of filtering
algorithm based on moving average filter and the data conversion method by
direct computation of the polynomial are verified in LabVIEW. A comparison test
with the commercial temperature measurement instrument is… More >
