Rotary Encoders offer integrated diagnostic capabilities.

Press Release Summary:




Utilizing ADS Online, Leine & Linde’s 850 Shaft Encoder and 861/862 Hollow-Shaft Encoders can provide problem-solving information directly to system operator. Advanced Diagnostic System helps ensure output voltage level is correct, output states change correctly, correct number of pulses are present each revolution, and that optics performs within defined levels for supply current and brightness. Vibration levels, hours of operation, and internal temperature are also measured and logged.



Original Press Release:



Unique Online Diagnostics for Motion Control



Are Now Available in Entire Leine & Linde 800 Rotary Line



Schaumburg, IL – Leine & Linde’s 800 series of rotary encoders, already a popular solution for measurement of speed and position in demanding applications, now boast integrated diagnostic capabilities in its entire line.  Utilizing the new ADS Online, all these encoders can now provide additional problem-solving information directly to the system operator.



Until now, Leine & Linde’s new ADS Online capabilities had only been offered as an optional module for existing encoders. The newest versions of Leine & Linde’s 850 shaft encoder and the 861/862 hollow-shaft encoders have now incorporated this functionality into the encoder foundation.



The addition of online access to the current capabilities of Advanced Diagnostic System (ADS) also brings enhanced functionality with vibration and temperature monitoring.  ADS Online monitors a number of parameters that are fundamental for the encoder function such as: output voltage level is correct, output states change correctly, the correct number of pulses are present each revolution, and that the optics performs within defined levels for supply current and brightness. In addition, vibration levels, hours of operation and internal temperature are also measured and logged. The operator can set alarm levels on any of these parameters, as well as set logging intervals for trend evaluation. By monitoring trends in performance, it is possible to predict end-of-life conditions and plan maintenance activities before a failure occurs.



For more information on these encoders, contact Bob Setbacken at HEIDENHAIN at 805-562-1160, or e-mail at bsetbacken@heidenhain.com, or write to HEIDENHAIN Corporation, 333 E. State Parkway, Schaumburg, IL  60173.



Leine & Linde is based in Sweden with exclusive North American distribution through HEIDENHAIN CORPORATION in Schaumburg, IL.  Leine & Linde is well known for offering high quality, heavy duty encoders of both the incremental and absolute type, are noted for their product robustness and design to cope with the harshest of environments, such as those with high vibration, dirt and cold temperatures.  These heavy, severe duty encoders are suited for drive and measurement applications and are often found in industries such as pulp and paper, forest and wood processing, agriculture, aggregate and mining equipment.
