Optical Incremental Encoders ensure absolute accuracy.
2013-01-28 14:28:39| Industrial Newsroom - All News for Today
Measuring 58 mm in diameter, OptoPulse EIL580 Series includes clamping flange encoders with 10 mm solid shafts, synchro flange encoders with 6 mm solid shafts, and 8–15 mm blind hollow shaft and through hollow shaft models. All feature finely graduated disc increments that provide 100–5,000 impulses/turn. Featuring solid die-cast housings with 1.5 mm aluminum walls, encoders' optical sensing capability ensures absolute accuracy and consistent signal quality in temperatures from -40 to +85°C.

Negative temperature: Understanding what happens below absolute zero
2013-01-08 21:55:03| Extremetech
Our familiar concept of temperature works pretty well for most solids, liquids, and gases -- it conforms to the general expectation that it should always be greater than absolute zero. What are we to make of a recent claim by a group of German researchers that they have created an experimental system where negative temperatures can be observed and measured?
