Abstract
A vibration type force detector comprising: a string to which a force to be measured is applied in the direction in which the string is tensioned; a driver for causing the string to vibrate at its natural frequency and simultaneously producing a series of pulses at a frequency in synchronism with the vibration of the string; a gate to which the series of pulses are applied; a counter for counting the series of pulses that have passed through the gate; means for providing a gating time determined in accordance with the result of the counting of the counter; and a controller for controlling the gate in accordance with the gating time. The gating time providing means is so arranged that as the vibration frequency of the string increases, the gating time lengthens.
