1、 Overview and Application:
LAType guided wave radar can emit high-frequency microwaves that propagate along the probe rod. Due to encountering the measured medium, the dielectric constant undergoes a sudden change, causing reflection. The time interval between the emitted pulse and the reflected pulse is proportional to the distance of the measured medium. Meanwhile, guided wave radar can also measure the interface between two different media, fully utilizing the difference in dielectric constant of the media. But the measurement condition is that the upper layer medium is non-conductive, or its dielectric constant is smaller than that of the lower layer medium10More than double. The pulse working mode can measure small dielectric constant media and is safe for use in various metal and non-metal containers,No harm to human body and environment. Coal plants, power plants, petrochemicals, food industries, and general industrial applications.
