UNIT FOR THE COLLECTION OF DATA ON MEASUREMENTS MADE WITH THE TRIAXIAL APPARATUS AND ALTERNATE SHEAR DEVICE

CENTRALE D'ACQUISITION DES MESURES A L'APPAREIL TRIAXIAL ET A L'APPAREIL DE CISAILLEMENT ALTERNE

The unit operated with a 8080 intel microprocessor, scans and collects measurements on four presses in accordance to the programs selected by the operator and contained in memories. The measurements are memorized in a zone of 1 k8-bit bytes for each press thus allowing up to 120 readings on the four position, force, pressure and volume sensors. The operator can see at any time the contents of these memory zones before punching so that the contents can be kept until processing is completed. The punched tape is processed on a hp9825 computer which draws stress, pressure or volume curves as a function of displacement and Mohr circles, and determines the intrinsic parameters of the material tested. In case of failure of the punching machine, a teletype can be connected in place of the vdu console and retrieve the measurements. (TRRL)
