CIRCUIT FOR CALCULATING LOAD CONVERSION OF TENSILE TESTING DEVICE

摘要

PURPOSE: A circuit for calculating load of a tensile tester is provided to perform a tensile test by accurately controlling a flux valve without alternation of a circuit board which is a load generation device by composing a circuit converting an analog signal input in a load control device to a digital signal. CONSTITUTION: An M1 socket for an interface between a load controller and a load conversion operation circuit is prepared. An analog/digital converter converts an analog load signal to a digital control signal by a start signal for performing load operation control input via the M1 socket and outputs to the M1 socket. A decade counter is prepared to output 4 bit BCD signals to the analog load signal by the start signal. A BCD-to-decimal decoder outputs decimal data according to the 4 bit BCD signal of the decade counter. A switching piece switches the output data of the BCD-to-decimal decoder. A display piece displays calibration state by the load signal by being connected to the switching piece and the analog/digital converter.
