A Jet-Edge Oscillator for Sensing Electrical Currents,
Abstract
A flueric oscillator was built and tested as a sensor for measuring electrical currents in bridge wires. The conductor (bridge wire) was mounted in one cavity of a jet-edge resonator oscillator. The results of the tests, in which the pressure an temperature of the air supply were held constant and the direct current through the bridge wire was varied from zero to 100 mA, show that the change in oscillator frequency, due to heating the wire, is proportional to the square of the current. The oscillator is used as the sensing element in a fluidic system being developed to measure currents induced in electroexplosive devices by radio or radar transmitters. (Author)
