Key Features of Optical Measuring Scales

• Scale housing in extruded anodized aluminum TA 16 - size mm 39 x 23 - section 461 mm² - weight Kg/m 1.245.
• Flexible coupling for compensation of dis-alignments and self correction of mechanical hysteresis.
• Lip seals for the protection of the internal grating made of rubber elastomeric 70.
• Slider set composed by reader head [P] and tie rod [T]. The housing of the circuit is water proof by a gasket and steel cover with incorporated cable clamp.
• Hybrid circuit for generation of signals. The accurate calibration of signals prevents any further unbalance [calibrated resistors substitute the potentiometers normally used].
• Internal gasket for further protection. A double barrier prevents any infiltration of pollutants.
• Stainless steel grating. Size mm 18 x 0.305 in a single piece also in "modular" scales. The grating is kept in position by the scale housing which leaves it free to expand without deformation in case of faulty installation.
• Lateral fixing of the grating.
• Self -regulation of the grating extension. The compression springs damp any variation of distance between the two constraints A and B [integral to the housing and so subject to variations caused by its thermal expansion coefficient, similar to that of the material used in the manufacturing of the machine]. The measurements become homogenous and relative to the temperature of 20° C [68° F].
• Shielded cable reinforced by plaited stainless steel protection. The conductors section [0.14 mm² for the signals and 0.22 mm² for the supply], allows it to be used for lengths over 50/60 m.
• Rubber gaskets for the protection of the scale ends.
• End caps used also for the lateral fixing of the scale.
