FIELD: electricity. ^ SUBSTANCE: device includes sensor (101), signal cables (102) and signal processing device. Sensor (101) includes transfer coil (p1), receiving coil (s1) and releasing coil (c1), which are inserted one into another. At that, axes of receiving and transfer coils are perpendicular to each other. Sensor (101) can be installed at outlet hole of copper channel of mould (103) or on upper flange (103a) of mould (103), or on upper part of copper channel of mould (103). ^ EFFECT: compact structure of sensor, increasing sensitivity and enlarging the range of measurements. ^ 8 cl, 2 dwg |
