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.
Claims6
A probe for detecting the level of electrically conductive liquids in a walled container having an inner chamber comprising:
- a probe housing having a bottom portion for insertion into the chamber of the walled container, and an inner chamber;
- insulating packing means secured in said housing on said bottom portion within the inner chamber;
- at least one compensating electrode having an insulating jacket and disposed through said packing means, the insulating jacked penetrating said packing means and extending into said container;
- and
- at least one measuring electrode having an insulating jacket and disposed through said packing means, said measuring electrode being spaced apart and elongated with respect to said compensating electrode and wherein its insulating jacket penetrates said packing means and extends into said container to substantially the same extent as said jacket of said compensating electrode with said jacket of said measuring electrode extending into said container at least as far as the insulating jacket of said compensating electrode.
