摘要: Electronic circuit for detecting small resistance changes in conductors of high wherein the conductor is connected between grid and cathode a tube as triode bias adjusted almost to point necessary current cut-off, such that some significant amount flows at all times. The may be sensing element an ion chamber. level serves identify alarm, no-alarm or outage condition with device.
