Radar

The instrument antenna sends tight electromagnetics pulses on base band 26 GHz (C-band). These pulses are irradiated and then reflected, from the product surface to be measured and received back by the same antenna. A method of time elongation, allows the assessment of the time of flight which, by its nature, is particularly short, to be able to calculate with accurancy the distance and hence the level of the product to be measured.
Dust, vapors, high temperatures and pressures are well tolerated and allow the use of units in critical conditions. An advanced computerized system by “envelope curve” and the possibility to map the false echo curve allow to improve the measurement in critical conditions. Thanks to the two-wire technology (2-wire) and HART communication makes the installation, the commissioning and the use of the units is very simple and intuitive.
The antenna of the instrument sends electromagnetics chirp pulses on W-band base.
These waves are irradiated by the antenna and then reflected, at least in part, from the surface of the product to be measured and received back by the same antenna.
A FMCW method, combined to Fourier transformation (FFT), is able to calculate with accurancy the distance and hence the level of the product to be measured. The W-band, with a sweep frequency of electromagnetic waves around 80 GHz, allows the detection of the products surface whose dielectric constant is low.
