Abstract

The sensitivity and linearity of linear variable differential transformers as displacement transducers is discussed. The results of measurements on the variation of sensitivity with low temperatures are presented for a commercially available device; the Schlumberger Industries SM3, used in conjunction with its OD3 conditioning electronics. The sources contributing to the temperature dependence are discussed and suggestions concerning how this may be reduced are made. The SM3 is shown to be robust on thermal cycling and a versatile extensometer for use in the determination of the mechanical properties of materials at low temperatures. Indication is given of how it can be used for the measurement of the thermal contraction of sample materials and in monitoring movement during cooling of cryogenic structures.
