Sensor For Electrometric Measurement

US Patent:
6495012, Dec 17, 2002
Filed:
Mar 31, 2000
Appl. No.:
09/541358
Inventors:
Kenneth S. Fletcher - Hartford CT
David N. Skinner - Milton MA
Ellen Candela - Cohasset MA
Michael M. Bower - Wareham MA
Assignee:
The Foxboro Company - Foxboro MA
International Classification:
G01N 27401
US Classification:
204435, 204420
Abstract:
The invention provides a sensor with a reference electrode and a flowing electrolyte which is particularly useful for measuring the ion concentration of a process solution. The invention includes a sensor having a pressurized reservoir which provides flow of an electrolyte, a non-metallic solution ground and a resistance temperature device bonded to a non-metallic solution ground. The invention provides sensors with greater accuracy and stability by minimizing or eliminating ingress of contaminants from a process solution through the external junction of the sensor.

Ph Glass Membrane And Sensor

US Patent:
2003017, Sep 25, 2003
Filed:
Oct 30, 2002
Appl. No.:
10/283615
Inventors:
Lauren Catalano - Wrentham MA, US
Ellen Candela - Cohasset MA, US
Kenneth Fletcher - Hartford CT, US
Michael Bower - Wareham MA, US
David Skinner - Milton MA, US
John Connelly - , US
International Classification:
G01N027/26
US Classification:
204/433000
Abstract:
A pH sensor including a reference electrode, a measuring electrode operatively connected to said reference electrode, a fluid conduit for containing an electrolyte in electrolytic contact with said reference electrode, a reservoir in fluid communication with said fluid conduit, a reference junction encasing said reference electrode, and an external junction, wherein said electrolyte comprises a viscous silica suspension to maintain a flow of said electrolyte from said reservoir to reduce inward diffusion through said external junction.
