Abstract

The invention discloses a non-contact wireless measurement device for solution concentration. The device comprises a measuring machine part which comprises a vertical polarized antenna, a horizontal polarized antenna and a non-contact measuring device used for containing a solution to be measured, wherein the non-contact measuring device comprises a liquid container and a micro-strip defected ground structure, and the liquid container is arranged on the micro-strip defected ground structure, the micro-strip defected ground structure comprises a micro-strip line and a double-opening slot resonant ring, and the transceiver part comprises a transceiver and a dual-polarization transceiver antenna which are in communication connection. The non-contact wireless measurement device for the solution concentration detects the change of the solution concentration by using a double-opening slot resonant ring structure, and the precision is high. According to the invention, non-contact telemetering measurement can be carried out on the change of the solution concentration; compared with a traditional microwave non-invasive measurement method, the method has higher sensitivity.

Description

technical field [0001] The invention relates to the technical field of solution concentration measurement, in particular to a non-contact wireless solution concentration measurement device. Background technique [0002] At present, the detection methods of solution concentration include specific gravity method, optical rotation method, spectrophotometry, ultrasonic method and refractive index method. The specific gravity method has the highest accuracy, but it is not suitable for rapid on-site detection; the optical rotation method is related to the composition of the solution, and its application range is limited. Although the ultrasonic method and the refractive index method can be well used for non-invasive detection, the accuracy depends on complex processing equipment, which is not only expensive, but also has a strong limitation on the application frequency range. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a ...
