Apparatus for calibrating pyrometer

摘要

Disclosed is a calibrating apparatus which is adapted to remove a measurement deviation of a pyrometer, and more particularly, to an apparatus for calibrating a pyrometer, which calibrates a reference value so as to remove a deviation in a temperature measured in a pyrometer. The apparatus for calibrating a pyrometer includes a blackbody including a radiant space from which radiant energy is radiated, a body housing configured to receive the blackbody therein and including a light output wall having a light output port connected with the radiant space, a light output wall protecting cover configured to be coupled with the light output wall of the body housing so as to define a passage connecting the light output wall of the body housing and an outside environment, and a fixing member configured to fix the light output wall protecting cover to the light output wall of the body housing.

1. An apparatus for calibrating a pyrometer, comprising:
a blackbody comprising a radiant space from which radiant energy is radiated; a body housing configured to receive the blackbody therein and comprising a light output wall having a light output port connected with the radiant space; a light output wall protecting cover configured to be coupled with the light output wall of the body housing so as to define a passage connecting the light output wall of the body housing and an outside environment; and a fixing member configured to fix the light output wall protecting cover to the light output wall of the body housing, wherein the light output wall protecting cover is spaced apart from and coupled to the light output wall of the body housing, wherein the light output wall protecting cover comprises a cover plate comprising an inner surface opposite to the light output wall of the body housing, and an outer surface located at an opposite side of the inner surface, and wherein an edge of the inner surface comprises a first inclined surface configured so that a thickness of the cover plate becomes thinner toward a distal end of the cover plate.
