Problems solved by technology

[0017] Using a larger sensor increases the area that can be tested, but larger sensors are not suitable for all applications
When only a small area needs to be sensed in an inaccessible location, a larger sensor may not be suitable as it may not fit in the available space
Even when the location is accessible, if only a relatively small area is of interest, using a larger sensor can lead to excessively long processing times for measurements relative to smaller sensors that may have been applied to the area of ​​interest

Embodiment Construction

[0072] refer to figure 2 , examples of devices for sensing electrochemical changes in objects will now be described. In this example, the device is a two-electrode electrochemical cell device 200 . The electrochemical cell device 200 has a substantially electrically conductive body in the form of a cell device housing 202 . The battery device housing 202 defines a cavity 204 which, in use, is filled with an electrolyte 206 . The electrochemical cell arrangement 200 also has a first electrode in the form of a counter electrode 208 . In this example, the electrochemical cell arrangement 200 also has a second electrode in the form of a reference electrode 210 . The electrodes are located within chamber 204 and are connected to cables 212 and 214 for electrical connection to a potentiostat or galvanostat when electrochemical cell device 200 is used to sense electrochemical changes in object 216 . In this example, battery device housing 202 contains two magnets 218 and 220 that a...

Abstract

Apparatus (200) for detecting corrosion of a coating (250) of an object (216), the apparatus comprising: an electrically conductive body (202) defining a cavity (204) for containing an electrolyte (206), the body (202) arranged to be, in use, in electrically conductive contact with the object (216) and arranged to isolate, in use, the electrolyte (206) from the object; and a first electrode (208)within the cavity (204), the first electrode (208) for electrical connection to a potentiostat (402) or to a galvanostat and arranged to be, in use, in electrical contact with the electrolyte (206) inthe cavity (204); wherein the body (202) comprises a first part (222) and a second part (224), the second part (224) being slidably movable relative to the first part (222) between a retracted position and an extended position.

Description

technical field [0001] The present invention relates to devices and systems for sensing electrochemical changes in objects. In an embodiment, it relates to an electrochemical cell device. In other embodiments, it relates to a system comprising the device. Background technique [0002] It is often desirable to be able to accurately detect electrochemical changes in certain objects. Detecting electrochemical changes in an object can, for example, help determine the maintenance requirements of the object. For example, if a significant electrochemical change is detected in the object, it can be determined that a protective coating needs to be applied or reapplied to the object, or that a part of the object needs to be replaced. If no significant electrochemical changes are detected in the object, it can be determined that no maintenance is required. Parts of various structures such as pipelines, automobiles, aircraft, and oil rigs undergo electrochemical change tests to dete...
