The Elbo range of optical lines can be fitted on most types of machine tools (horizontal and vertical lathes, milling machines, grinding machines, radial drilling machines, EDM ma-chines, boring machines, etc.) and metrological instruments (profile projectors, hardness gauges, thickness gauges, etc.)
The MX modular version, which allows you to combine 6-metre modules, features applications for large machines (over 20 metres).
The measure is carried out by transparency (up to 3,000 mm) or reflection (over 3,000 mm) depen-ding on the model.

Measuring
In the optical line models with transparency me-asuring, infrared emitters send out a beam that hits the phototransistors by crossing a collimator and a graduated glass line. Following a shift between the graduation of the glass line and the collimator, the intensity of the infrared beam on the phototransistors varies, creating sinusoidal signals proportionate to the graduation pitch. These signals are then processed and transfor-med into signals for displays or positioners.
In models with lengths over 3,000 mm, reading is done by reflection on a specially-graduated steel line.
