The paper describes a varying frequency telemetering system which employs an electron tube beat frequency oscillator, the frequency of which is controlled by a small condenser mounted upon the movement of the instrument, the reading of which is to be transmitted. The reading is reproduced at the receiving end by a frequency meter having a scale corresponding to that of the transmitting meter. When furnishing a single indication, the outstanding feature of this system is that except for the… CONTINUE READING
