    Abstract: THE INVENTION RELATES TO LOD-MEASURING INSTRUMENTS WHICH EMPLOY ELECTRICAL MEANS AS THE LOAD-MEASURING MEANS. IN THE INSTRUMENT OF THIS INVENTION, THE LOAD-MEASURING MEANS COMPRISES A PAIR OF TENSIONED STRINGS WHICH ARE ELECTRICALLY EXCITED TO VIBRATE. A LOAD IS APPLIED TO SAID STRINGS SO AS TO VARY THE TENSION WITH A CONSEQUENT VARIATION IN THEIR VIBRATION FREQUENCY, WHICH INFORMATION IN TURN IS TRANSMITTED TO A DIGITAL DEVICE WHICH TRANSLATES IT INTO A LOAD-INDICATING QUANTITY.

    Abstract: A vibrator includes a vibrator element and a base on which the vibrator element is installed. In addition, when n is set to a natural number equal to or greater than 2, and j is set to a natural number equal to or greater than 1 and equal to or less than n, the vibrator element includes n inherent vibration modes having resonance frequencies different from each other, and when a resonance frequency of a main vibration of the vibrator element in the n inherent vibration modes is set to ω1 in a relationship between an arbitrary integer kj and a resonance frequency ωj corresponding to each of the n inherent vibration modes, the following three expressions are all satisfied. Δω ≡ ( ∑ j = 2 n  k j  ω j - k 1 - ω 1 ) / ω 1  ω 1  ≥ 0.1   3 ≤ ∑ j = 1 n    k j  ≤ 10
