X-ray tube monitor circuit - for cut off by excessive high tension, tube current or power

Schaltungsanordnung zur ueberwachung einer roentgenroehre

Abstract

A main relay in the tube power supply unit is operated by e.g., a Schmitt trigger stage connected to the output of a summing amplifier fed on one input with a composite sum signal representing measured tube EHT and limiting EHT, measured tube current and limiting tube current summed in a Milman ladder circuit and on the other input with a signal representing limiting power, all three analogues of voltage, current and power limiting values being derived from potentiometers across a stabilized reference voltage. Simplicity and safety.
