  • Platform transducer beams
    Patent number: 4515232
    Abstract: Conventional transducer beams, and in particular platform load cells, can be simply and economically protected from accidental damage that may be incurred during handling and shipping. Safety screws, preferably of high strength plastic, are inserted in threaded holes that are drilled through the transducer beam so that the screws take up substantial portions of accidental loads, thereby protecting the fragile sensing sections of the transducer beam. The safety screws are to be left in place until the units are incorporated into respective platform type scales and the scales are installed for their ultimate use.
