Patent ES-344282-A1 (ES)
Title: Measuring apparatus delivering pulses at a frequency proportional to the measurement
IPC: G01L11/00
Filed: 1967-08-21
Abstract: In a force balance system, a signal in the form of pulses, the frequency of which is proportional to the magnitude of a force tending to deflect the balance beam, is produced from the feed back circuit of the system. If Fig. 1, deflection of a beam 4 pivoted at 5 produces a change in inductance of a coil 12 connected to an oscillator 13, a ferrite block 6 fixed to the beam moving with respect to the coil 12. The resulting output of the oscillator is a varying direct current I which is fed to a coil 7 on the beam via a lead 17, which coil 7 cooperates with a permanent magnet 8 to restore balance. A circuit for producing pulses in dependence upon the magnitude of restoring current includes a pulse generator 16 comprising a capacitor 24 Fig. 2, which is charged up by the feedback current I in lead 17 and is discharged through a uni-junction transistor 25 when the voltage at the base thereof exceeds a predetermined value V. The frequency of pulses thus produced is given by formulae f = I/CV. The output of the pulse generator may be fed to a pulse shaping or a frequency multiplying circuit 21. Capacitor 19 is for pulser smoothing and potentiometer 20 is for calibration purposes. The balance beam may be coupled to a Bourdon tube 1 to measure pressure, as shown in Fig. 1, or to other types of transducer responsive to a physical variable.
