FLUERIC SENSOR FOR RF-INDUCED CURRENTS IN BRIDGE WIRES

Abstract

A simple system that employs the nonlinear fluid resistance of an orifice to detect the heat generated by small currents in bridge wires has been tested. The system utilizes the dependence of the orifice flow resistance on temperature to indicate the current through a bridge wire and produces an analog pressure readout. The system has a threshold of about 15 mA (for an 8.5-ohm bridge wire) and a thermal time constant of 3.5 sec. Suggestions are given for possible ways of improving both sensitivity and response time.
