Moze on równiez sluzyc do ciaglego pomiaru masy i objetosci materialów sypkichjak zboze, piasek, ruda, wegiel itp.Zastrzezenie patentowe Cyfrowy miernik do ciaglego pomiaru ciezaru i objetosci przemieszczanego materialu, zwlaszcza ryb, przenoszonych za pomoca przenosnika, wyposazony w czujnik i dwa tory pomiarowe dolaczone do ukladu wejsciowego, z którym polaczona jest elektroniczna bramka sprzezona z generatorem impulsów, do której to bramki sa polaczone szeregowo licznik, dekoder i wyswietlacz, stanowiac pierwszy tor pomiaru objetosci, zas drugi, równolegly tor pomiaru ciezaru stanowia dolaczone do ukladu wejsciowego szeregowo druga elektronicz¬ na bramka sprzezona z drugim generatorem impulsów oraz licznik, dekoder i wyswietlacz, znamienny tym, ze uklad wejsciowy tworza wejsciowy wzmacniacz (2) z dolaczonym komparatorem (3) i dolaczonym don generatorem (3) przebiegu odksztalconego.Prac. Poligraf. UP P RL naklad 120+18 Cena 45 zl PLThe subject of the invention is a digital measuring device for the continuous measurement of the weight and volume of the material moved, especially fish. The invention relates to metrology, in particular to measuring mass continuously. Measuring devices for continuous measurement of weight are known. These are conveyor scales with digital readings. These known devices sum the values of the instantaneous readings of the sensors electrically and are based on the principle of counting the product of the instantaneous power values in time and used in electricity meters, or they have an electric motor at the input, the rotation of which - depending on the fluctuations of the electricity consumed - is counted in An abacus. The well-known counter is quite well suited for measuring the weight of the material being moved, but it is quite sensitive to fluctuations in temperature, humidity, and also to the inclination of ships. For these reasons, in practice, it is not suitable for work on ships where there is a need to continuously measure the weight (and volume) of the fish being moved. The aim of the invention was to develop a digital meter for the continuous measurement of the weight and volume of the material being moved, especially fish, without any disadvantages. According to the invention, the purpose is implemented by an electronic meter, which is equipped with an input circuit, consisting of a matching input amplifier with an attached comparator and an attached distorted waveform generator. This type of meter is a simple to build and operate system, and also cheap. The electronic meter has small main dimensions. It can be attached both to the recorder and to the computer, as well as to be used in the automation system. The subject of the invention is presented in an exemplary embodiment on the diagram. The meter for the continuous measurement of the weight and volume of the material moved, especially fish, according to the invention consists of a known sensor 1, connected to the matching amplifier 2, which in turn is connected to comparator 3. To the input of comparator 3 is connected distortion waveform generator 4.2 111188 The comparator 3 input is connected to an electronic gate 5 connected and controlled from a controlled pulse generator 6. The first electronic gate 5 is connected in series with a counter 8, a decoder 9 and a display 10, and is the first path for the weight measurement. The second path for the volume measurement contains the second e, respectively electronic gate 7 connected to a pulse generator 11 connected in series with a counter 12, a decoder 13 and a display 14. The digital meter operates as follows. The voltage signal from sensor 1 is amplified in the matching amplifier 2 and is fed to comparator 3 together with the waveform from the distortion waveform generator 4. The signal from the comparator 3 is fed to the electronic gate 5 together with the pulses from the controlled pulse generator 6. The pulses passing through the electronic gate 5 are counted in the counter 8, decoded in the decoder 9 and displayed by the display 10. The settings of the controlled pulse generator 6 are proportional to the speed of the conveyor belt and to the weight unit, and the settings of the controlled pulse generator 11 are proportional to the speed of the specific weight belt conveyed on the conveyor belt and the volume unit. Thus, on the way as described previously, using the second measuring path, 14 volume values on the cork display. The digital meter for continuous measurement of the weight and volume of the transported material, especially fish, is used in social economy as a measure of mass (weight) and volume of fish on the technological lines of fishing vessels, deep-sea fishing and on ships processing plants. It can also be used to continuously measure the weight and volume of bulk materials such as grain, sand, ore, coal, etc. to the input circuit, which is connected to an electronic gate connected to the pulse generator, to which gates are connected in series with the counter, decoder and display, constituting the first volume measurement path, while the second, parallel weight measurement path is the second electronic path connected to the input circuit in series a gate coupled to a second pulse generator and a counter, decoder and display, characterized in that the input circuit forms an input amplifier (2) with an attached comparator (3) and an attached generator (3) of the distorted waveform.
