Nondestructive, Microwave Testing of Compression Strength and Moisture Content of Green Molding Sands
نویسندگان
چکیده
Abstract A nondestructive microwave testing method to control the green compression strength and moisture content was proposed demonstrated. There are various moulding sands, both qualitative (bentonite type) quantitative water content), prepared. The permittivity measurements were performed by cavity perturbation technique (CPT) at 2.45 GHz. Relative complex of bentonite bonded sands is proportional inversely compressive strength. It shown that obtained value molding be used investigate content.

Nondestructive Microwave Measurement of Moisture Content and Mass of Single Peanut Kernels
Principles for determining moisture content and mass of individual peanut kernels by microwave resonator measurements are discussed, and data are presented showing the application of these principles. By measuring the shift in the resonant frequency and the change in the cavity transmission characteristics when a peanut is inserted into the cavity, it is possible to obtain the moisture content ...
متن کاملNondestructive sensing of bulk density and moisture content in shelled peanuts from microwave permittivity measurements
Dielectric-based methods were used to determine nondestructively and simultaneously bulk density and moisture content in shelled peanuts from measurement of their relative complex permittivity at microwave frequencies (7–12 GHz) and 24 C. The first method is based on direct relationships between the two components of the relative complex permittivity (dielectric constant and dielectric loss fac...
متن کاملA Review of Microwave Thermography Nondestructive Testing and Evaluation
Microwave thermography (MWT) has many advantages including strong penetrability, selective heating, volumetric heating, significant energy savings, uniform heating, and good thermal efficiency. MWT has received growing interest due to its potential to overcome some of the limitations of microwave nondestructive testing (NDT) and thermal NDT. Moreover, during the last few decades MWT has attract...
