Filed: 1973-10-18
Abstract: 1460899 Electromagnetic weighing apparatus INTERNATIONAL ELECTRONICS Ltd 18 Oct 1974 [18 Oct 1973] 48699/73 Heading G1N [ Also in Division H3] Weighing apparatus comprises a movable system responsive to the weight of an imposed mass and provided with a coil disposed in a magnetic field; and a controllable current source for energizing the coil in response to a control signal representing in magnitude and sign the displacement of the movable system from a datum position, the control signal being applied to the current source via an amplifier system of which the A.C. gain is arranged to be increased in response to an input signal of which the A.C. component exceeds a predetermined amplitude. A coil 8 attached to a movable load-carrying member (not shown), and disposed in the gap 3g of a permanent magnet system 3, receives current from the collector of a transistor 45 having an emitter resistor 46. The same current also excites a fixed flux compensating coil 8c and flows through a resistor 43, the resultant P.D. being indicated by a digital voltmeter 44. The transistor 45 output current is substantially unaffected by disturbances in its collector potential due, e.g. to EMFs induced in the coil 8 by vibration. A signal applied across terminals 25, 30, representing in magnitude and sign a displacement of the movable member, is applied to an amplifier 33 driving the base of the transistor 44 and having two negative feedback paths. A first feedback resistor 38 determines the gain of the amplifier when the input signal changes slowly. In the steady state a resistor 63, short-circuited by a FET 62, provides via a capacitor 64 and a second feedback resistor 66 a heavy A.C. feedback, making the amplifier 33 insensitive to small fluctuations in input due to vibration of the movable member. A second amplifier 35 fed with A.C. displacement signals via a capacitor 34 amplifies these and applies them to a threshold circuit 52 having two parallel branches each comprising a Zener diode 53, 55 connected in opposition to a rectifier diode 54, 56, the two branches being connected to apply positive peaks to an inverting input, and negative peaks to a non-inverting input, of a third amplifier 59. Thus if a large fluctuation occurs in the displacement signal, e.g. a transient change due to the composition of a load, a resultant negative-going output from the amplifier 59 turns off the FET 62, adding the resistor 63 into the A.C. feedback loop of the first amplifier 33 to increase its sensitivity, and thus causing the apparatus to respond promptly.
