AUTOMATIC MEASUREMENT SYSTEM OF DEFORMATION FOR CREEP TESTS

In order to realize automatic measurement of creep deformation of creep specimens,A set of automatic measurement system is established,which includesing three subsystems: displacement-measurement,data acquisition and supervisory control and data processing. The overall system integrated effectively by the three subsystems implements the automatic dynamic measurement of minor creep deformation through a computer and sixteen displacement sensors. The minor creep deformations of eight specimens are able to display and record at the same time by a computer.
