Patent ID: 8510070

Claim:
A device for measuring the temperature of an exterior surface of a rotating roll that is rotatable about a longitudinal axis that comprises: an air temperature sensor, which is housed in a chamber having an entrance and an exit, and which is configured to be positioned adjacent the surface of the rotating roll such that a gap is established between the air temperature sensor and the surface of the rotating roll; a guide panel having an exterior surface with a curved contour that matches the exterior surface of the rotating roll and positioned downstream of the entrance of the chamber wherein rotation of the rotating roll causes air to flow through the gap and diverts turbulent air into the entrance of the chamber and onto the air temperature sensor, and wherein the air temperature sensor generates first signals that are indicative of the temperature of the air that comes into contact with the air temperature sensor; a compensator temperature sensor that generates second signals that are indicative of ambient temperature; a standardizing sensor that generates third signals that are indicative of the surface temperature of the roll; and means for calculating the temperature of the surface of the rotating roll based on the first signals, second signals, and third signals.
