Detects and responds with 0.1% linearity to core displacement. Low-level ac transformer output is converted to 10 to 50 ma d-c transmission signal with : w maximum power by high-input-impedance feedback amplifier. Precision exciter consists of constant-voltage 1-kc oscillator and high-Q swamping choke. Gain is stabilized by using separate d-c feedback loop for each group of d-c coupled transistors.-L. H.
