DEVICE FOR DETERMINATION AND/OR MONITORING OF MEDIUM LEVEL IN RESERVOIR Russian patent published in 2008 - IPC G01F23/284 

FIELD: technological processes; measurement.

SUBSTANCE: invention is related to the sphere of measurement equipment and is intended for determination and/or monitoring of medium level in reservoir. In invention the input unit consists of at least one first conducting element and one sealing ceramic part, at that the sealing ceramic part is installed as highly chemically stable, temperature resistant and/or resistant to pressure of separation from the process in the area between both conducting elements together with the first seal, which is installed between the first conducting element and ceramic sealing part, together with the second seal, which is installed between ceramic sealing part and second conducting element, at that the first seal and/or second seal is made in the form of graphite stuffing box. Glass terminal is provided as gas-tight separation from the process in the area between ceramic sealing part and regulating/processing unit. The space around the internal conducting element and external conducting element, which is found between the ceramic sealing part and glass terminal, is almost fully filled with dielectric material. Also ceramic support part is provided for prevention of slipping or displacement under effect of axial tensile or pressure strain, and also radial forces that affect the internal conducting element.

EFFECT: creation of device for monitoring of medium level in reservoir that is suitable for application in the area of high temperatures and/or high pressures.
