Level Sensor - Non-Contact Radar in measurement of caustic soda, acidic corrosive liquid

Coherence: Coherence is produced by coherent current-driven dipole oscillations, or by nonlinear difference-frequency effects ofcoherent laser pulses.
Low energy: The energy of millimeter wave photons is only a few millielectron volts, and there is no phenomenon of X-ray
ionization and destruction of the substance to be detected, so it is not easy to destroy the substance to be detected.
Strong penetrability: It has strong penetrating power for non-polar substances. Many non-metallic non-polar materials absorb less radiation in this band. Therefore, they can be used to detect the internal structure of materials. For example, ceramics, cardboard, plastic products, foam, etc. , are transparent to electromagnetic radiation in this band, and can also be used for security detection in airports and stations, such as detection of machinery, explosives and drugs, or for circuit board welding detection.
