Sensors As Tough as You Are

If your environment is dirty, hot, wet, or corrosive your requirements may have some similarities with that of the construction industry.

Why Holistic Encoders are More Accurate

All absolute rotary encoders have a rotor which is attached to the rotating shaft and a stator which is attached to the housing holding the shaft. The interaction of these two components produces a measure of the shafts rotational angle. The most important parameters of absolute rotary sensors are resolution, accuracy and tolerance to misalignment of the rotational axes.

Inductosyn: End of an Era, New Opportunities or Both?

Recently, obtaining the Inductosyn and components for maintenance has become more difficult. For decades the Inductosyn from Farrand Controls / Ruhle Companies sat near the top of the rotary sensor hierarchy. Providing sub 2 arcsec (0.5 mdeg) accuracies, it combined the robustness of a resolver with the performance of the best optical encoders. Despite its shortcomings, it found plenty of customers, from airborne infrared and radar systems, to telescopes, satellite communication antennae (SATCOM), machine tooling and low-pressure vacuum chambers.

Expanded VLP Encoder Series Offers Control Engineers New Sensing Options

Everight Position is pleased to announce the addition of four new sizes of Netzer’s two-plate VLP rotary encoder amongst other improvements. Based on the success of the VLP-60 and VLP-100, the new options include the VLP-80, VLP-140, VLP-170 and VLP-247.
