Ear measuring device for cupping deep drawing test ERICHSEN
ISO 11 531

Ear Measuring Instrument, Model 126

Used to obtain a numerical value of the size of the ears resulting from anisotropy in the material of cylindrical deep-drawn cups (e. g. according to DIN 50 155). The average cup height, the height of the ears in percent and in mm can be read-off at a touch of a button and are shown on the digital display instrument. To enable additional data processing the test instrument can be equipped with interfaces, such as BCD or RS 232 C outputs and with a printer.
