Description

one

The invention relates to the field of instrumentation technology and can be used in the engineering and instrument-making industry for measuring the angle of inclination of the electrical conductor of sh. Their surfaces.

A device for contactless measurement of the angle of inclination, containing, its generator and an eddy current transducer connected to it with orthogonally located exciting and indicator coils and connected in series to an indicator coil in series connected amplifier, phase-sensitive unit and indicator, is known.

Such a device does not allow to determine the azimuth and has low accuracy due to insufficient temperature stability.

The purpose of the invention is to improve the accuracy of measurement of the angle of inclination and the definition of azimuth.

For this, the proposed device is equipped with a rotation angle converter into an electrical signal, kinematically connected with it and an eddy current transducer for rotating the eddy current transducer around its own axis and connected in series with each other and parallel to the phase-sensitive unit by an amplitude detector, a phase output detector and a logic circuit with two inputs; The reference input of the phase detector is electrically connected to a converter of the rotation angle into an electrical signal, and the indicator coil of the eddy current transducer is rigidly connected to the exciting and nominal source in the plane of symmetry of the latter.

The imp is the block diagram of the proposed device.

The device contains a generator 1, an eddy-current converter 2, a rotation angle converter 3 into an electrical signal, a drive 4, an amplifier 5, an amplitude detector 6, a phase detector 7, a phase-sensitive unit

8, logic circuit 9 and indicator 10.

The device works as follows. The signal from generator 1 enters the eddy current converter 2. In the case when the rotation axis of the eddy current converter 2 is perpendicular to the electronically conducting surface (not shown in the drawing), the signal from the indicator coil (not shown in the drawing) is zero due to the symmetry of the electromagnetic field. When the angle of inclination of the surface at the output of the indicator coil changes, a modulated signal appears, the amplitude of the envelope being proportional to the angle of inclination and the phase to the azimuth. After amplification, the signal enters the input of the phase-sensitive unit 8 and the amplitude

detector-array 6. The polarity of the output voltage: the phase-sensitive unit 8 indicates the sign and the magnitude is the measured angle. With a 1m, 1, a full detector 6, a low frequency signal is fed to a phase detector 7, the reference input of which receives a signal from a rotation angle converter 3. The output 1 - phase phase detector, which is proportional to the phase of the low frequency signal, determines the azimuth of the angle of inclination of the electrically conductive surface.
