METHOD FOR DETERMINING LIQUID HELIUM LEVEL WITH A DISCRETE LEVEL METER

摘要

A method of measuring liquid helium level with a discrete level gauge with a point sensor containing a resistive temperature sensor of the TVO brand and a measurement process control controller, characterized in that they analyze the change in the sensor resistance values when it is powered alternately with a current of 0.1 and 3 mA and the value of the resistance jump is phase of the substance.
