from many aspects influence factor consideration, based on advantages such as microwave method measuring speed is fast, the precision is high, the error is little among the indirect method, the utility model discloses a microwave method is applied to among the detection of crude oil moisture content.
Microwave refers to electromagnetic wave with frequency of 300 MHz-300 GHz, and is a short for a limited frequency band in radio wave, i.e. electromagnetic wave with wavelength of 1 mm-1 m, which is a general term for decimetric wave, centimeter wave and millimeter wave. The microwave frequency is higher than the frequency of a general radio wave, and is also generally called "ultra high frequency electromagnetic wave". Microwaves also have a wave-particle duality as an electromagnetic wave. The basic properties of microwaves are generally represented by three characteristics, namely penetration, reflection and absorption. For glass, plastic and porcelain, microwaves almost pass through without being absorbed. Absorbing microwaves to water, food and the like to heat the food; and to the metal class, then can reflect the microwave, all kinds of advantages of above microwave can satisfy the utility model discloses required all requirements, promptly:
1. the frequency is high, the frequency band is wide, so that the working frequency band is high when a sample is detected, and the power frequency and low-frequency electromagnetic interference resistance is strong;

3. the medium intrinsic information detection device has penetrability, scattering property and thermal effect, and can be used for detecting the intrinsic information of the medium by utilizing the characteristics of microwave reflection, absorption and penetration.
The water molecules belong to strong polar molecules, the centers of positive and negative charges are not overlapped, and the dipole moment is very strong. In the microwave field, water molecules can generate positive and negative charge stretching to generate polarization action and molecular rotation collision, and energy is lost as heat energy. Petroleum hydrocarbon mixtures, with weakly polar dielectrics, have a dielectric constant that varies with frequency. Therefore, the water content can be measured by utilizing the difference of high-frequency complex dielectric properties of water and petroleum. Under the action of a high-frequency external electric field, the water pole can be reoriented and rotationally polarized, and the energy of the electric field can be stored in potential energy due to the stretching of positive and negative charges; the molecules rotate and collide, and energy is lost through thermal energy.
