Abstract
A caliper gauge for relatively thin moving sheet material is provided by the use of a pair of outer ring air bearings flexibly supported which tend to flatten the sheet. An inner central portion of each ring respectively carries active and passive magnetic circuit means with the passive means being supported by an elongated strap of Kevlar which is elongated in the machine direction of the sheet material. This provides for very low unsprung weight.
