  • Volume sensor for paddle elevator using laser light
    Patent number: 6115115
    Abstract: A laser sensor for detecting the volume of particulate material being conveyed by a paddle conveyor. The sensor comprises two opposed units, a master unit and a slave unit. Each unit is provided with a single laser emitting diode and four photo detectors. The master unit is provided with a microprocessor for providing a square wave laser firing signal to the lasers. The slave unit is provided with an inverter for inverting the laser firing signal from the microprocessor. The lasers are fired sequentially when they receive a high pulse from the square wave emitted from the microprocessor. The photo detectors transmit their laser light detection signal when they receive a low pulse from the microprocessor which indicates the opposed laser has fired.
