Summary:A spark detector indicates the presence of a spark by analyzing sound waves generated when an electrical spark is produced from an electrical spark generator located on an igniter rod. The spark detector includes an acoustic sensor that is in communication with the igniter rod to determine the time for the spark sound wave to travel through the igniter rod to the acoustic sensor. If a spark is not detected, the spark detector may output a signal indicating at least one of (i) the spark was not detected, (ii) to replace the electrical spark generator immediately, or (iii) replace the electrical spark generator soon such as at the next scheduled maintenance. Furthermore, the spark detector may be calibrated based on current temperature of the igniter rod based upon time of propagation of a pulse sound wave, generated by a pulse-echo generator, to reflect off an end of the igniter rod.
