Abstract

The invention discloses a metal thermoelectric potential detection instrument comprising a measuring device and a control device which controls the measuring device. The measuring device comprises a box body with a work board, a fixing device which fixes metal to be detected on the work board, a first probe component which can be movably arranged in the box body along an X-axis direction and a Z-axis direction, a second probe component which can be movably arranged in the box body along the Z-axis direction, an X driving mechanism which is used for driving the first probe component to move in the X-axis direction, and a first Z driving mechanism and a second Z driving mechanism which are respectively used for driving the first probe component and the second probe component to move in the Z-axis direction. The X-axis and the Z-axis are mutually perpendicular, and the Z-axis is perpendicular to the work board. The metal thermoelectric potential detection instrument is convenient to carry and can measure various sizes of metal parts in the industrial field so that the metal thermoelectric potential detection instrument is high in reliability and has certain automation function.

Description

technical field [0001] The invention relates to a metal thermoelectric potential detection instrument, which belongs to the field of metal material detection. Background technique [0002] The measurement of metal thermoelectric potential is based on the Seebeck effect. The Seebeck effect is that in a circuit composed of two metals A, B or different parts of a metal, due to the different temperature of the two contact points, a current will be generated, which is called a temperature difference current, and there is a corresponding potential difference ΔV AB . The experiment found that the potential difference ΔV AB Proportional to the temperature difference ΔT, its ratio S AB =ΔV AB / ΔT is a function that depends on the temperature difference and the two materials, it is completely independent of the shape of the material, the connection method, etc. and has linear superposition, so S AB It is a basic property of the material, which is called the Seebeck coefficient of...
