ABSTRACT:
A short-circuited loop of conductor 10, 32, 44, 54 comprises an electromagnetic short-circuit hoop probe which is electrically insulated from a gas stream passing therethrough either by spatial isolation (FIG. 2) or by a coating of electrical insulation (FIGS. 3-5), whereby to reduce noise and DC current levels which could otherwise pollute signals of interest therein. A large hoop version of the non-contact probe permits electrostatic diagnostics of gas streams downstream of flame (FIG. 2).
