Model 126 Plus / -Optic

The Ear Measuring Instruments, Model 126 Plus and Model 126 Plus-Optic, are designed for the axial measurement of deep-drawn cups and raw cans. Typical standards are DIN EN 1669 and ISO 11531.

The Ear Measuring Instrument, Model 126 Plus, consists of a turntable and a vertical gauge head with a roller. By a jaw chuck, the cup is centered and fixed. The gauge head can be positioned to different cups heights and diameters. Once the measurement process has started, the test roller, activated pneumatically, lowers onto the sample and the turntable rotates once. During this rotation, the measuring head records the shape of
the cup’s edge, known as the earring.

The Ear Measuring Instrument, Model 126 Plus-Optic, uses an optical sensor as the measuring unit instead of the length measuring probe, which enables non-contact measurement of ultra-thin aluminum.. The chuck is not required with this option. The cup is magnetically attached to a rotary table. When the measurement starts, the optical sensor automatically moves to the measuring position and detects the earring of the cup during the turnable rotation
