Abstract

PURPOSE: To enable to detect the displacement over a long stroke, with zero tracking of the differential transformer detecting error with the servo control.
CONSTITUTION: The pulse motors 23 and 9 are turned when the pulse generator 24 is operated and forward output is made from the control circuit 25, and the cross head 2 is up with the feed screw 4, tensile load is exerted to the test piece 3 via the hydraulic servo actuator 10, the test piece 3 is displaced and the coil 13 is lifted up in the differential transformer 12. In this case, the core 14 of the differential transformer 12 is lifted up. The core 14 of the differential transformer 12 tracks the zero, the number of pulses from the pulse generator 24 is the displacement of the test piece 3, and it is displayed with the display unit for displacement via the correction circuit 17. The hydraulic servo 10 is in servo control so that the output of the differential transformer 12 is zeroed via the chuck.
