Abstract

984,419. Determining physical qualities; measuring bridges. ELECTRONIC SWITCHGEAR (LONDON) Ltd. March 21, 1961 [March 21, 1960], No. 46842/64. Divided out of 984, 418. Headings G1N and G1U. A device 10 capable of changing its electrical resistance in response to a variable condition to be measured has one terminal connected to one output diagonal point a of a Wheatstone bridge 19 through the inner conductor of a screened cable 11, the outer conductor of which is connected to the opposite output diagonal point b. The arrangement is used in the liquid conductivity measuring arrangement described in Specification 984,418, the bridge being automatically rebalanced by a motor which drives the slider of potentiometer 15 in response to an output from the bridge. It is stated that the arrangement effectively eliminates the effect of the self capacitance of the connecting cable 11.
