ABSTRACT:
A device for detecting an interface between two fluids of differing electrical properties, said device having an electrical circuit comprising transmitting means for transmitting electrical impulses to said fluids, a detector of electrical impulses, and at least one probe which is adapted to extend into said fluids; said probe comprising an electrically conductive probe member and a grounded electrically conductive shield, the probe member being mounted within the shield and being spaced from the latter by an air core, the probe member adjacent its distal end portion, being sealed to the shield by a dielectric seal which prevents the ingress of said fluid into the space between the shield and the probe member.
