Abstract
An electronic weighing apparatus of induction type comprises a weighing member adapted to be moved according to the weight of a load to be measured, a variable inductance element consisting of a coil and a magnetic core which is movable relatively to the coil through the coil, a connecting member for connecting the weighing member with one of the coil and the magnetic core of the inductance element so that the one can be moved with respect to the other according to the movement of the weighing member and thus the inductance of the inductance element can be changed proportionally to the movement of the weighing member, a sensor oscillator including the variable inductance element as one of its oscillating parameters for generating a series of pulses having a characteristic representative of the inductance of the variable inductance element, a converting circuit for converting the characteristic of the output pulses from the sensor oscillator into a weight signal indicative of the weight of the load, and a display for receiving the weight signal from the converting circuit and providing an indication of the weight of the load.
