titleOfInvention | Method and device for measuring the physical parameters of a material |
abstract | The technical solution relates to measurement technology and is intended for measuring the dielectric permittivity and moisture content of high-conductivity loose, paste-like and fluid materials such as saline slurry, anthracite, ore material, crude oil and oil sludge. The present method is based on using a sensor in the form of a segment of a long transmission line, and involves feeding a high-frequency probing signal from a frequency-tunable generator to an input of the sensor, and measuring the harmonic frequencies at which the length of the signal conductor of the sensor is equal to or a multiple of half of the wavelength of the probing signal in the material filling the sensor. The harmonic frequencies are determined on the basis of a voltage minimum at the output of a detector in the form of a phase discriminator, the output voltage of which reaches a minimum when the input signals of the detector are either in-phase or anti-phase. Inputs of the detector are coupled to an input and an output of the sensor via segments of a coaxial cable which have the same electrical length, said segments being matched at the outputs. Designs for a moisture sensor for carrying out the above method are proposed. For the purpose of carrying out measurements in pipelines, the sensor is configured in the form of a pipe containing a signal conductor. For loose materials in hoppers and on conveyor belts, the sensor is configured in the form of a screen, to which a U-shaped bar is fastened. The technical result is increased measurement accuracy. |
