Potentiostat data link

摘要

A potentiostat data link (PDL) unit is provided which can remotely monitor the formation and growth of cracks in metal structures. A PDL includes a sealed box containing two or more modified potentiostats, a power supply, a CPU, a memory device, and computer networking capability. The PDL can be mounted in a remote, difficult-to-access location. Each potentiostat has a lead to a sensor affixed to a structure to be analyzed for the presence of growing cracks due to metal fatigue in a metal structure.

主权项

1. A potentiostat data link, comprising:
an enclosure; at least one pair of microprocessor controlled potentiostats, wherein each potentiostat: (a) has a sensor lead to a sensor affixed to a structure to be analyzed for the presence of growing cracks due to metal fatigue in a metal structure, (b) comprises a programmable voltage setting and an analog-to-digital converter and (c) is electrically isolated from the rest of an electronic circuit board of the device; a power supply; and a ground connection, wherein the potentiostat is used to monitor the fatigue status of the metal structure.
