摘要： An ultrasonic bin level control circuit which employs a fail-safe circuit to shut off a compressor when echoes are late or absent, and a transducer mounting system which facilitates installation and removal of a transducer for servicing and cleaning. A level detector compares a reference signal with a reflected signal, the ice reaching a desired level when the reflected signal overlaps the reference signal. When the desired level is reached, the reference signal is modified through feedback to prevent short cycling of the compressor. The transducer is installed within a cylindrical housing which is easily installed and removed from a cylindrical socket within a compartment above the bin.
