Appl. No.:

10/742470

Inventors:

Stephen B. Talutis - Milton MA, US

Assignee:

Invensys Systems, Inc. - Foxboro MA

International Classification:

G01N 1/00

US Classification:

738665

Abstract:

An interlocked valve sensor insertion assembly for use in a manufacturing process is shown and described. The assembly includes a ball valve configured to alternately couple and decouple a retraction chamber with the process. An insertion assembly is coupled to the retraction chamber, and includes an axially slidable insertion tube with a sensor supported on one end. The tube has a range of motion capable of extending the sensor into the valve. A fastener releasably couples the tube to the insertion assembly, and an actuator is configured for engagement with both the valve and the fastener. The actuator is configured to alternately engage and disengage the fastener when the valve is respectively disposed in open and closed positions.

International Classification:

G01R 31/28

US Classification:

3241581

Abstract:

This invention relates to electrical connectors used with non-invasive toroidal conductivity sensors and calibration thereof. A removable breaking calibration connector is provided for temporary insertion in the electrical circuit to selectively break connection to a sense toroid for zero out calibration in situ while retaining connection to the drive toroid and other peripherals, even when process fluid is flowing in the pipes.

International Classification:

G01N 27/06
G01N 27/74

US Classification:

324445, 324439, 324204

Abstract:

A non metallic flow through electrodeless conductivity sensor is provided with a conduit having primary and secondary process fluid flow paths to form a fluid loop. At least one drive and one sense toroid surround the conduit on the fluid loop. Voltage supplied to the drive toroid induces a current in the sense toroid via the fluid loop to eliminate any need for metallic electrodes in contact with the process fluid. At least one additional drive and/or sense toroid is disposed on the fluid loop to enhance induction. Optionally one or more sense coils are disposed about the conduit outside of the fluid loop to cancel out stray electrical noise. An optional conductor disposed along the conduit detects any fluid leakage through changes in resistance thereof. A temperature detector is supported within an electrically non-conductive holder extending into the fluid flow path, so that the detector is free from physical contact with the fluid. An optional enclosure is provided with ports to enable a user to purge any gas permeating the conduit walls.

US Classification:

20429701, 2042861, 20429715, 204400, 204409, 738665

Abstract:

An adjustable insertion assembly for an electrochemical sensor includes an electrode holder to receive the sensor, having a distal aperture to permit process fluid to contact the sensor. A receptacle slidably receives the holder, for a sliding range of motion extending from fully inserted to fully retracted positions. An open distal end portion of the receptacle extends through a wall of a process fluid vessel, so that the aperture is open to the process fluid when fully inserted, and closed when fully retracted. A leverage member is releasably movable relative to the receptacle, and moves with a captured extension. An abutment of the receptacle engages the extension so that movement of the leverage member in opposite directions alternately clamps and releases the electrode holder relative to the receptacle to substantially prevent and permit movement at substantially any point within the range of movement.

International Classification:

G01N027/02

US Classification:

324445000

Abstract:

A sensor includes primary and secondary toroids disposed in spaced, coaxial relation to one another with a process flow path extending therethrough. Electrically conductive and non-metallic connectors are located at opposite ends of the flow path to physically contact the process fluid flowing therethrough. The primary toroid is configured to induce an electric current in the process fluid as the process fluid passes through the flow path, wherein the current varies with conductivity of the process fluid. The secondary toroid is configured to detect the electric current in the process fluid as the process fluid passes through the flow path, the current being proportional to the conductivity of the process fluid.

International Classification:

G01N 27/26

US Classification:

204433000, 204400000

Abstract:

In an ionic-activity sensor, an osmotic pump drives a reference-cell electrolyte to flow through an interface with the solution to be measured. This minimizes contamination of the reference cell by that solution. The driving force results from expansion of an electrolytic-agent reservoir into which solvent from a solvent reservoir diffuses through a semi-permeable membrane. The electrolytic-agent reservoir contains an electrolytic-agent solution in which a quantity of undissolved is disposed to keep the electrolytic-agent solution saturated as solvent diffuses into it.
