Engineers have long been s e a rching for reliable and repeatable methods to measurethin gaps between 0.010”(0.254mm) and 0.125”(3.18mm). Mechanical contact methods such as feeler gauges,shims and calipers had longbeen the only available methodto measure gaps, even in are a sw h e re damage could be causedto polished or sensitive surf a c e s .Capacitec has eliminated there q u i rement for the operator’s“feel” inherent in feeler gaugesby developing a broad line ofnon contact industrial gap sensors as well as a newp o rtable gap measurement toolnamed GAPMAN Significant scientific and engineering enhancements inadvanced materials, Pre-and I n - P rocess production methodsand in-situ testing methods aredriving the demand for displacement sensors that canhandle extremely high t e m p e r a t u res up to 1832°F(1000°C). Contemporary p roducers of continuous flowsteel, plate glass and plasticsnow use off-the-shelf high t e m p e r a t u re Capacitec sensorsolutions for in-process applications to control the quality of their production on areal time basis. Qualification testing of disc industrial brakes, jet enginedynamics and high speed shaft rotations also rely on Capacitecsensors. Advanced materials forautomobiles, structural components, and aircraft arealso tested for strength anddurability with the use ofC a p a c i t e c ’s line of extensome-ters and clip gauges. Maintaining the perfect alignment of a particle detectorin a gap measuring only0.050” (1.3mm), at 300°F(150°C) and in a chamberexposed to 2 tesla magneticfield along with 10 M i c ro p rocessor chips havefound their way into a surprisingly high number ofp roducts that are around use v e ry day in our home, car ando ffice. This explosion in worldwide demand has forc e dsemiconductor manufacturers toenhance quality and thru-put inways never before imagined.C a p a c i t e c ’s microinch levelpositioning sensing systemsassist chip processing and handling equipment m a n u f a c t u rers to sense s i l i c o nwafers for exact positioningprior to deposition, etching andother processing. This is accomplished without cominginto contact or damaging theirhighly sensitive surfaces. Otherindustries where sensitive s u rfaces must be measure d ,damage free, are printingp resses, photocopier ro l l e r s ,computer hard disc drives andmolten materials.

Hereagain Capacitec sensors sustainthis challenging enviro n m e n twhile taking critical blade tipclearance measurements at1600°F (871°C).
