‘Absolute Encoder’

An Engineeringtalk guide

Start with the news release Renishaw Tonic benefits wide-format printing from Renishaw, which we summarised at the time by saying "Renishaw's Tonic incremental linear-encoder system offers advantages for wide-format printing. ". Several months prior to that, we featured the news release Moving coil actuators have no mechanical backlash from SMAC Europe: "SMAC electric direct drives utilise moving coil technology, which the company said provides long life and high reliability in comparison to conventional pneumatic devices.".
 
In November 2009, we covered the news from McLennan Servo Supplies - take a look at Brushless servo motors provide 2,800-5,200rpm which says: "The Ametek Pittman brand AB series brushless servo motors are available from Mclennan Servo Supplies in NEMA 23, 34 and 56 frame sizes. ".
 
Take a look also at the news release from Yokogawa, Yokogawa pH sensor suits aggressive solutions, as well as Rotary encoders provide 1nm and 2nm resolutions from Renishaw, and RDP transducers give direct analogue output from RDP Electronics.
