The invention relates to an
infrared temperature measurement device for high-temperature
vacuum sintering furnaces, which comprises a baffling
barrel, a window
flange, a piece of glass, a mounting
flange, a supporting plate and a temperature
detector, one end of the baffling
barrel is sealed to form a sealed end, the other end of the baffling
barrel is open, the edge of the window
flange is provided with screw holes, the mounting flange, the glass and the window flange are arranged coaxially, moreover, the glass is located between the mounting flange and the window flange, and the mounting flange and the window flange are fixed oppositely in order to fix the glass. The
infrared temperature measurement device for high-temperature
vacuum sintering furnaces adopted by the invention measures the temperature of the thermal field of a
sintering furnace by measuring the temperature of the sealed end surface of the baffling barrel, the arrangement of the sealed end ensures that high-temperature
sintering volatile matters cannot enter the baffling barrel, thus ensuring that the transmission path of an
infrared ray does not have foreign matters, and thereby the
temperature measurement precision of the infrared temperature
detector is increased. The invention also provides a high-temperature
vacuum sintering furnace.
