Excerpt: It should be obvious that the “heartbeat” of a process shouldn’t stop, leaving a machine without speed or distance feedback. But outputs occasionally do stop working for many OEM and industrial machines, leaving them with a complex troubleshooting question: Where did their encoder feedback …
Non-magnetic encoders for high-magnetic fields
February 16, 2012 by Paul Dvorak

Excerpt: A company known for long-lasting miniature scales and small profile scanning units now manufactures a line of encoders that are non-magnetic. These linear and rotary encoders have been tested in environments up to six Tesla and have no influence on the machine environment. The encoders can also …
Encoders 101

Excerpt: Most double-feed induction generators require encoder feedback for top performance and line synchronization. But the high vibration and temperature extremes kill even “heavy duty” optical encoders. Recent encoders have been designed for wind turbine applications. The devices indicate the ang …
Encoders slash downtime for generators

Excerpt: A line of encoders fit existing shafts and flanges while offering high durability. Avtron says its devices’ bearings are rated to over five times greater loads, and include magnetic sensors that shrug off dirt, grease, condensation, and oil. The encoders slash wind-turbine generator downtime while …
