Description

Известны устройства дл  измерени  модул  вектора физического пол , в которых измерение осуществл етс  с помощью трех взаимноперпендикул рных магниточувствительиых элементов, токи которых пропускаютс через квадраторы вентильного типа и суммируютс  на сопротивлени х . Приблизительна  квадратична  зависимость характеристик вентильных элементов дает значительные ощибки при измерении. Кроме того, в этих устройствах в результате измерени  получаетс  не модуль , а квадрат модул  измер емого вектора.Devices for measuring the modulus of a physical field vector are known, in which the measurement is carried out using three mutually perpendicular magnetically sensitive elements, the currents of which are passed through valve-type quadrants and summed over the resistances. The approximate quadratic dependence of the characteristics of the valve elements gives significant errors in the measurement. In addition, in these devices, as a result of the measurement, it is not the module that is obtained, but the square of the module of the measured vector.

Описываемое изобретение лишено указанных недостатков.The described invention is devoid of the indicated disadvantages.

Принципиальна  схема устройства приведена на фиг. 1.A schematic diagram of the device is shown in FIG. one.

На .магниточувствительные элементы , МЧЭ2, МЧЭз действуют соответствующие составл ющие вектора магнитного пол  А , У, Z. Выпр мленное выходное напр жение усилител , например, 1 подаетс  в компенсационную обмотку MV5i. При достаточно большом коэффициенте усилени  этого усилител  разность между величиной X и полем компенсационной обмотки будет весьма мала, а следовательно, выходное напр жение усилител  У,., будет пропорционально с большой точностью составл ющей X, независимо от величины коэффициента усилени  усилител , характеристики выпр мител  и чувствительности МЧЭ,,. Аналогично обеспечиваетс  пропорциональность составл ющих У. Z соответственно напр жени м Vy, V, . Если посто нные компенсационные обмотки равны между собой, то напр жение на выходе усилителей , очевидно, характеризует величины проекций вектора в одном н том же масштабе.The magnetosensitive elements, MCHE2, MCHEZ are affected by the corresponding components of the magnetic field vector A, Y, Z. The rectified output voltage of the amplifier, for example, 1 is fed to the compensation winding MV5i. With a sufficiently large gain of this amplifier, the difference between the magnitude of X and the field of the compensation winding will be very small, and therefore, the output voltage of the amplifier Y,. sensitivity MCE ,,. Similarly, the proportionality of the components U. Z is ensured, respectively, of the voltages Vy, V,. If the constant compensation windings are equal to each other, then the voltage at the output of the amplifiers, obviously, characterizes the magnitudes of the projections of the vector on the same scale.

Выпр мленное напр жение этого усилител  через ключ 4 также подаетс  на квадратор .The voltages V, Vy, V, are supplied via the keys Si, lo, Bz and bB to the quadrant Kv. quad.
