The invention relates to the technical field of conductive material level detection, and provides a conductive material level detection probe and a measuring device in a conductive container. The material level detection probe of the conductive material in the conductive container includes: a driving rod, at least one end of which extends into the conductive container and extends along the height direction of the conductive container; an electrode, which is arranged on the driving rod, corresponds to the preset material level setting of the conductive capacitor, and the electrode and the conductive capacitor are connected through the conductive parts; the driving rod is connected with the driving part outside the conductive container. Because the electrode and the conductive container are connected by conductive parts, when the material level in the conductive capacitor reaches the height of the electrode, a conductive circuit is formed between the electrode and the conductive container, and then based on the conductive characteristics of the conductive circuit, the material level can be measured to reach the height of the electrode. In addition, when the driving part rises, it can drive the driving rod to move to the outside of the conductive capacitor, and then the driving rod can be removed from the conductive container, so as to facilitate the maintenance and replacement of the conductive material level detection probe.
