Non-destructive solution concentration detection device and detection method based on magnetic resonance coupling

Abstract

The present invention relates to the field of the resonant magnetic coupling-based wireless energy transmission and concentration detection technology and particularly relates to a resonant magnetic coupling-based nondestructive solution concentration detection device and a detection method. The device comprises a temperature monitoring and controlling apparatus, a network analyzer connected with a computer, and test equipment connected with the network analyzer. The test equipment comprises a resonant magnetic coupling system. The resonant magnetic coupling system comprises a transmitting end and a receiving end. The device overcomes the defect in the prior art that a solution crystallizes on a conventional sensor and even corrodes the sensor during the concentration measurement process of the solution by means of the conventional sensor. Meanwhile, the defects that due to the anti-corrosion material arranged on the surface of the conventional sensor, the measurement accuracy is greatly affected and the usage of an instrument is therefore influenced are also overcome. A coating is added onto the surface of a resonance coil, so that the solution crystallization and the corrosion are effectively prevented. The long-term measurement is enabled by the resonance coil, and the resonance coil can be drawn out and then cleaned. Therefore, the nondestructive detection of the solution is realized. The device and the method have a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of concentration detection by magnetic resonance coupling wireless energy transmission, and in particular relates to a nondestructive solution concentration detection device and detection method based on magnetic resonance coupling. Background technique [0002] Concentration is one of the important parameters to characterize the characteristics of medium solution. The measurement and control of solution concentration is widely used in papermaking, chemical industry, sugar refining, food, pharmaceutical and other industries. It is an important technical means to ensure and improve product quality. When ordinary sensors are used to measure the concentration of the solution, the solution will produce crystallization on the sensor and even corrode the sensor. If anti-corrosion materials are added to the ordinary sensor, it will greatly affect the measurement accuracy, thereby affecting the use of the instrument...

Problems solved by technology

However, when ordinary sensors are used to measure the concentration of the solution, the solution will produce crystallization on the sensor and even corrode the sensor. If an anti-corrosion material is added to the ordinary sensor, it will greatly affect the measurement accuracy, thereby affecting the use of the instrument.
