Apparatus and method for measuring temperature and electrical resistivity of a movable object

摘要

An apparatus for connecting an electrical measurement system, which includes at least a first and a second conductor, to a movable object to measure at least one of a temperature and an electrical resistivity of the movable object includes a first and a second connector, and a first and a second contact wire. The first and the second contact wires are electrically communicable with the first and the second conductors, respectively, and are wound around at least a portion of the first and the second connectors, respectively, such that the first and the second contact wires are engageable with the movable object at a first and a second contact point, respectively. The first and the second contact wires each has a polarity. The first and the second connectors are made of a material having a higher electrical and thermal resistivity than the first and the second contact wires.

1. An apparatus for connecting an electrical measurement system to a movable object to measure at least one of a temperature and an electrical resistivity of the movable object, the electrical measurement system having at least a first conductor and a second conductor, the apparatus comprising:
a first connector and a second connector each rotatable about a fixed axis; a first contact wire electrically communicable with the first conductor, the first contact wire being wound around at least a portion of the first connector such that the first contact wire is engageable with the movable object at a first contact point; and a second contact wire electrically communicable with the second conductor, the second contact wire being wound around at least a portion of the second connector such that the second contact wire is engageable with the movable object at a second contact point; wherein the first contact wire and the second contact wire each have a polarity; and wherein the first connector and the second connector are each made of a material having higher electrical and thermal resistivity than the first contact wire and the second contact wire.
