TEMPERATURE-COMPENSATED QUANTITATIVE DIMENSIONAL MEASUREMENT DEVICE WITH PROGRAMMABLE IN-TOLERANCE/OUT-OF-TOLERANCE INDICATIONS

摘要

a gauge (10) controlled by a computer is used to measure the size and temperature of workpieces, such as the diameter and the temperature of axle steel for railway wagon. it indicates whether or not the tolerances of each measure, and the value of quantitative measurement.on the basis of the predetermined coefficient of expansion of the workpiece (100), a gauge (10) calculates the dimension of the workpiece (100) would have if she were similar to conventional reference temperature predetermined 59u00b0f.from the dimension of the room temperature compensated as a result of the calculation, and from the range of dimensional tolerance set manually, the axle (100) is reported in (i) and (ii) large repair, as in a range of size, (iii) sousdimensionnu00e9 but repairable), or (iv), undersized and non repairable.the gauge (10) can also detect its own temperature and, in the light of a further predetermined expansion coefficient is adapted to calculate the dimension of the gauge, the gauge, temperature compensated, and the workpiece.
