Extension measurement equipment and yield measurement equipment of stretch test

摘要

(57) Abstract (Modified) Objective Extension measurement or yield measurement of stretch test is done, specialYield measurement is done making use of the micro-computer occasionIt does, assures measurement precision and the improvement of working capacity. Constitution The Tip of 2 these arms which come out of the extensometer stretch testOpening specified interval to the piece, the test which you install, in the time of stretch testThe extent of the arm interval which accompanies the extension of the piece electric resistance of gaugeIt detects amplifies the said detection signal with the amplifier as change of anti- value,It extends on the te XY recorder and it records as - stress characteristic curveIn the ru extension measurement equipment, in XY recorder entry the voltmeterWhile jointing, visualizing amplifier output the zero point of the XY recorderIt makes the adjustment possible, without requiring the skill, at brief zero point pitch of the equipmentTry to be able to produce the section.
