Take clear vases or bottles, fill them with water, add holiday-colored food coloring--a few drops will do--and float candles in them!

This system has perfected continuously in actual application and it can make the processing manner of removing zero drift, processing and correcting unusual point, calculating strain rosette etc true.

This paper analyses the origin of the temperature drift of the bridge offset for the piezoresistive pressure sensors and presents some of the compensation technique to minimize it.
