Abstract: A probe for detecting the level of electrically conductive liquids in a walled container having an inner chamber consisting of a probe housing having a bottom portion for insertion into the chamber of the walled container, and an inner chamber, an insulated packing secured in the housing on the bottom portion, at least one compensating electrode having an insulating jacket and disposed through the packing, the insulating jacket penetrating the packing and extending into the container and at least one measuring electrode having an insulating jacket and disposed through the packing, wherein the electrode is elongated and spaced apart from the compensating electrode and extends beyond its insulating jacket into the container.

Abstract: An electrode device for use in monitoring conductive liquids consisting of a mounting with a first electrode having a tie rod portion disposed through the central opening of the mounting and a clamping collar secured to the tie rod adjacent to one side of the mounting. The first electrode then extends further in an extending portion and is surrounded coaxially by a second tubular electrode which is connected through a contact sleeve disposed in the central opening of the mounting. There is also a counterelectrode coaxially surrounding the second electrode and secured to the mounting surface. The second electrode has an end flange portion with a passageway for receiving the rod portion of the first electrode. The clamping nut secures the rod portion of the first electrode and the end flange between insulating washers to the mounting.
