ABSTRACT:
An apparatus for monitoring the operation of a heating element moving periodically along a predefined path includes first and second sensors positioned adjacent the path of the heating element. The first sensor is configured to sense the presence of the heating element proximate to the second sensor, and the second sensor is configured to sense a temperature associated with the heating element as is passes by the second sensor. A controller receives signals from the first and second sensors and performs a control function such as indicating when the temperature sensed by the second sensor fall outside a predetermined range.
