Electronic apparatus for continuous weighing of heavy loads by means of electronic circuits for conversion of weight values to electrical signals that can be stored and processed on electronic calculators, microprocessors, etc.

摘要

Electronic apparatus for weighing of loads in general and heavy loads in particular, consisting of a metal support structure of the load and at least one load transducer or cell placed between the plane of the load and the base, electrical circuits connected to the metal structure, comprising a differential amplifier connected in a bridge with said load cell, a converter of voltage to frequency and an output stage comprising a power amplifier; said apparatus also comprises in a separate container from said structure, a circuit to process data transmitted via cable from said output stage, consisting of an amplifier- squarer of the wave shape connected to a series of integrated decadic meters and connected to a wave pulse generator to obtain the equivalent in BCD code of the frequency of the input signal and then parallel binary outputs storable in RAM memory capable of emitting the requested operations by electronic calculators, microprocessors and printers, even remotely controlled. The apparatus is then provided with circuits to control the temperature of the components, for activation of alarms, and a power supply circuit for a balanced direct current. IMAGE
