Removable breaking calibration connector for toroidal conductivity sensor and method of calibration
First Claim
Patent Images
1. A removable breaking calibration connector portion for effecting zero out calibration in-situ for a toroidal conductivity sensor having a drive toroid and a sense toroid disposed in communication with an analyzer, the breaking calibration connector portion comprising:
- a first interface configured for communicable engagement with one of the analyzer and sensor;
a second interface configured for communicable engagement with the other of the analyzer and sensor;
circuit elements disposed electrically between said first and second interfaces, said circuit elements configured to temporarily block electric signals between saidanalyzer and said sense toroid, and to pass electric signals between said analyzer and said drive toroid;
wherein said calibration portion permits zero out calibration of the sensor without emptying the sensor of process fluid.

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.
