As if the selection of manufacturer weren't enough, many encoders offered in today's marketplace are highly configurable. Resolution, shaft size, seal options and connector variations all confront the design engineer with serious choices. Output type is equally important. In this paper, we'll cover some of the more typical applications and common output types.
In most drilling applications encoders are used to provide position and speed feedback for proper control of equipment like top drives and pipe racking systems. However, these electronic devices require special attention when used in hazardous environments such as a drilling platform. In this paper, we discuss ways to make encoders suitable for hazardous duty.
