Abstract
An air flow detecting system is provided for monitoring air flow in a dryer system. The dryer system has an exhaust passage through which air from a drying compartment flows. The air flow detecting system includes a detector for monitoring a rate at which air from the drying compartment travels through the exhaust passage, and a signal generator. The signal generator is responsive to the detector and generates an electrical signal for which at least one of phase, frequency, voltage, or current varies over a continuous range based on a measured flow rate.
