  • Weighing apparatus with vibratory string force sensor
    Patent number: 5232063
    Abstract: A weighing scale includes a vibratory string force measuring device (1) the frequency of which varies as a function of the applied load. The load signal from the vibratory string device is supplied to a microprocessor (8) where it is processed with a first frequency signal supplied by a temperature-responsive first quartz oscillator (9), thereby to produce a load measurement output signal (GW), the first frequency signal serving also as the clock signal for the microprocessor. The microprocessor also compares the first frequency signal with a second frequency signal supplied by a temperature-independent second quartz oscillator (11), thereby to produce a temperature compensation signal (TW).
