LVDT Position Sensors for Large Multi-Mirror Astronomical Telescopes
|
From Macro Sensors, A Division of Howard A. Schaevitz Technologies
In newer astronomical observatories, the mirrors used in reflecting telescopes are not single mirrors cast in one piece like in the older telescopes, but in fact they use small mirror segments that are computer-aligned for the purpose of exactly locating them in the contour of the mirror. Invariably they use LVDTs to maintaining that position. Products & Services
Position probes measure the position of a target surface, usually with a high degree of accuracy. This search form covers many different linear position products.

Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core. These devices produce an electrical output proportional to the position of the core
