APPARATUS FOR MEASURING TEMPERATURE

摘要

The present invention relates to a temperature measuring apparatus. The temperature measuring apparatus comprises: an apparatus frame; a non-contact type temperature measuring means which is installed on one side of the apparatus frame and measures the temperature of an object disposed on the other side of the apparatus frame; and a foreign substance removing means which is installed on the other side of the apparatus frame to be disposed between the non-contact type temperature measuring means and the object and removes foreign substances from the non-contact type temperature measuring means to the object by spraying the air. The temperature measuring apparatus includes the non-contact type temperature measuring means to measure a temperature in a non-contact type with respect to the surface of a main piece at the time of measuring the temperature of the main piece, thereby preventing irregularity in temperature of the main piece in a width direction. Moreover, the temperature measuring apparatus includes the foreign substance removing means for removing foreign substances from the non-contact type temperature measuring means to the main piece by spraying the air, thereby securing a field of vision appropriate for a measurement path of the non-contact type temperature measuring means. Furthermore, the air is sprayed obliquely to the main piece at the time of spraying the air to remove foreign substances, thereby preventing the main piece from being undesirably cooled at the time of measuring the temperature of the main piece.
