초록

A high pressure electrical conductivity probe generally used as a liquid level indicator having a high pressure mechanical seal between an insulator and a metal mounting body and an electrode connector. The high pressure mechanical seal is effected using a cylindrical insulator with planar end faces which are located in and sheathed in cylindrical recesses in the metal mounting body and the electrode connector. Preferred sealing means include flexible expanded graphite gaskets or a mechanical interference fit.

청구항

An electrical conductivity probe designed to withstand high pressures comprising a conductive electrode connector, a metal mounting body, means for conductively mounting said metal mounting body to a pressure vessel, an external terminal, means providing an electrical connection between said electrode connector and said external terminal adapted to complete an electrical circuit when a conductive liquid comes into contact with said electrode connector and a wall of a pressure vessel to which the probe is adapted to be mounted through electrical, conducti...
