A system and method is provided for determining a speed of a belt moving along a transport axis in conveyor oven tunnel. The method includes providing a sensor module, capturing signals, processing the signals, and outputting least one speed estimate. The sensor module is disposed upon the moving belt. The sensor module includes a first optical sensor and a second optical sensor. The optical sensors are spaced apart by a distance D along the transport axis. Capturing signals includes capturing first and second signals from the first and second sensors respectively as they are transported along the belt and within the oven tunnel. Processing the signals includes determining a delay &#x394;T between the signals. The speed estimate is based upon D divided by &#x394;T.
