MOCON-TAB cigarette pack moisture analyzer

MOCON-TAB cigarette pack moisture analyzer

Using 2.40GHZ low-frequency microwave (which can penetrate high-density non-metallic oversized packaging boxes), the attenuation and phase change caused by microwave transmission through the medium are mainly determined by the dielectric constant and dielectric loss tangent of the medium. Water is a polar molecule, and its dielectric constant and dielectric loss tangent are higher than those of ordinary media. Usually, the dielectric constant and loss tangent of an aqueous medium are mainly determined by its moisture content. The microwave emits energy from the microwave emitting probe located on the left side of the packaging box, and after passing through the tested material, the remaining microwave energy is received by the microwave receiving probe on the right side.

Based on the attenuation of microwave power and changes in phase shift, as well as the calculation of instantaneous total mass using ultrasonic quality compensation probes, the moisture content of the material can be calculated using computer system software based on the percentage content of total energy loss and total mass.
