FIELD: measurement equipment.SUBSTANCE: device for determining the layer height of the substance flowing via an aeroflow conveyor includes an emission source connected at its outlet to emission input element, emission output element connected to the input of polarisation plane turning angle metre, and winding. The device includes a converter, an amplifier, an actuator and a power supply unit. Output of polarisation plane turning angle metre is connected to the converter input, the output of which is connected to the amplifier input. The amplifier output is connected to the first arm of the actuator; the second arm of the actuator is connected to the first arm of the power supply unit, the second arm of which is connected to the beginning of winding; end of winding is connected to the third arm of the actuator.EFFECT: reduction of power consumption.1 dwg |
