Abstract
1383772 Temperature variable resistances PFAUDLER-WERKE AG 10 May 1972 [11 May 1971] 21907/72 Heading H1K A resistance thermometer assembled on an enamelled support, e.g. a tube, comprises a four wire supply circuit enabling measurement to be made independent of wiring resistance, in which pairs of Pt wires from terminals A, B, C, D are bridged and connected at junctions 1, 2 to a measuring loop E, of Pt strip folded into elongate parallel paths. The remote end of the loop is bridged at 3 to establish a predetermined resistance value, and the input wiring, the bridges 1, 2, 3, and the loop are coated and fired with several enamel layers while leaving a window F free from enamel overlying a further bridge 5 and a zone of the loop, so that the resistance of the latter may be accurately adjusted by positioning the bridge. Thereafter enamel is applied to the window zone and fired on to insulate and protect the loop. Alternatively the loop may be coiled about the tube.
