  • Method and apparatus for temperature compensation of measurements from a non-contact sensor
    Patent number: 6180939
    Abstract: A temperature compensation system (300) is provided for compensating measurements from a sensor (240). A temperature transducer (310) is placed in close proximity to a manufacturing workstation as a means of measuring the ambient temperature associated with the workstation (200). A reference workpiece (100) is placed within a sensing zone of the sensor (240). The system (300) includes a temperature compensating module (320) that is connected to the sensor (240) and to the temperature transducer (310) for determining a baseline measurement of the reference workpiece at a reference temperature. The temperature compensating module (320) is further adapted for collecting a plurality of measurements of the reference workpiece over a plurality of temperatures for establishing a relationship between these measurements and their corresponding temperature values.
