When one of these wheels is mounted on the shaft of an encoder, the result is an accurate and reliable instrument for measuring linear motion and position. “Rotary encoders do a great job of measuring rotary motion in shafts and other machine components,” comments Jarrod Orszulak, Product Manager at POSITAL-FRABA Inc. “However, for many motion control systems, accurate linear positioning is the main objective. With the new measuring wheels, we have a very convenient way of making linear displacement measurements while taking advantage of the proven performance of our extensive line of rotary encoders. This is a great solution for equipment positioning tasks or for cut-to-length applications.”
The new measuring wheels are available in circumferences of 200 mm and 500 mm. When fitted to multi-turn IXARC absolute encoders, this would translate into a linear measurement range of up to 500 kilometers! Three rim treatments are available – knurled aluminum, smooth polyurethane and textured (knobby) polyurethane – to ensure good traction between the wheel and a variety of surfaces.
Orszulak继续说:“我们非常兴奋combination of measuring wheels and our programmable incremental encoders. With this arrangement, a user could define exactly how many pulses the instrument would produce for a defined unit of linear motion”. IXARC programmable encoders can be easily calibrated at the job site using POSITAL’s convenient UBIFAST programming tool.
