Elbo s.r.l. Strumenti di misurazione e Metrologia Optical lines ELBO MEASURING SYSTEMS The GALILEO systems, with limited overall dimensions, permit a high accuracy and can be fi tted on machine tools such as lathes, boring machines, grinding machines, milling-planing machines, measuring benches, etc. On the contrary, the MXRL systems are designed for large machines and offer the possibility to add different shorts lenghts, to obtain measures over 10 metres. The encoders E-66 and M-2 are able to survey angular movements and to be driven by measuring racks. The range of GALILEO linear transducers includes 3 models differing for dimensions, strokes and output signal. Each model is available with 0.005 or 0.001 resolution and TTL or EIA-422-A output. The GT5 and GT1 models are optical scales for universal uses and are available with strokes from mm. 50 to mm. 1800. The GR5 and GR1 models give output signals according to EIA-422-A standard for applications to CNC, etc. The GL5 and GL1 models are optical scales with reduced dimensions and are available with strokes from mm. 50 to mm. 600. The MX model has oversized dimensions and it is available with stroke up to mm 3050.

Emitters (1) send out an infrared beam which passes through a collimator (2) and a graduated glass line (4), then activates phototransistors (5). Because of the graduation shifting between glass line and collimator, the intensity of infrared beam received by phototransistors varies, creating sinusoidal signals proportional to the graduation pitch. Then, these signals are processed by interpolation electronic circuits which transform them into square wave signals for displays, positioners and numerical control devices. In linear measuring systems, the reading component is protected by an aluminium container (7) provided with fl exible gaskets (6) in order to avoid oil, dust and chip penetration. These measuring systems are particularly suitable for usage on machine tools such as: milling machines, boring machines, lathes, punching machines, grinding machines, measuring benches, enlargers, presetting, microscopes Optical lines "GALILEO" series GT5GT1GR1GL5GL1MXCross section (mm x mm)21.5 x 33,5 length 50/180020,0 x 29,0 length 50/60037 x 56,5 length 1500/3100Measuring standardGlass scale - grating period: 20 micronOptical detecting systemTransmissive infrared wave lenght : 880 mmSlide carrier systemVertical 5 bearing supporting system Resolution5 micron1 micron1 micron5 micron1 micron5 micronMax. traversing50 m/min10 m/min10 m/min50 m/min10 m/min50 m/minAccuracy 50 600 mm± 6 micron± 4 micron± 4 micron± 7 micron± 5 micron± 10 micron 650 - 1000 mm± 10 micron± 8 micron± 8 micron ± 10 micron 1100 - 1500 mm± 10 micron± 8 micron± 8 micron ± 10 micron 1600 - 1800 mm± 10 micron± 8 micron± 8 micron ± 10 micron 1900 - 3150 mm ± 10 micronOne-direction repeatability2 micron1 micron1 micron2 micron1 micron2 micronTwo-direction repeatability5 micron2 micron2 micron5 micron2 micron5 micronHysteresis3 micronProtectionDIN 40050 IP53Power supplyDC V ± 5% OPTIONAL 12 V ± 5%Output signalsTTLTTLEIA - 422 - ATTL/EIA - 422 - ATTL/EIA - 422 - ATTL/EIA - 422 - AReference mark1 in line centre Standard cable5 mOperating temperature(0 - 50) °C http://www.elboitaly.it Powered by Joomla!
