Title: A TRANSISTORIZED CURRENT-CONTROLLED OSCILLATOR FOR DC-EXCITED STRAIN GAGE APPLICATIONS

Abstract

The Transistorized Current-Controlled Oscillator (TCCO) is a practical device for providing a frequency modulated signal directly proportional to the appropriate excitation phenomena such as stress, pressure, acceleration, and in some instances, temperature. The unit was designed primarily for airborne FM-FM telemetry applications. The TCCO is simple from the standpoint of number of parts. It consists of only three functional components: the DC amplifier, the variable inductor, and the oscillator. Each of the functional components was designed to provide maximum reliability and stability of operation. The use of transistors, a subminiature toroidal inductor, and printed wiring have made possible a compact, rugged, low-cost unit with extremely low power requirements. The TCCO provides a unique method of converting the output of a resistance bridge transducer to a proportional frequency modulated signal with the required accuracy and stability. (auth)
