Radar Level transmitter

Introduction

MODEL: SC / L-150X

The Radar uses an Frequency of 80GHz and works on Frequency Modulated Continuous Wave. The FMCW Radar emits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected from the measuring surface and received with a time delay, t. Delay time, t=2d/c, where d is the distance to the product surface and c is the speed of light in the gas above the product. For further signal processing the difference Δf is calculated from the actual transmit frequency and the receive frequency. The difference is directly proportional to the distance.

The electromagnetic wave travels at a very high speed (nanosecond), so it is difficult to identify it: CW COMPACT/REMOTE WAVE 26 GHz Radar Level Meters, thanks to their integrated management system, use a suitable demodulation technology that allows them to identify the period of time between the emission of the impulses and their corrected reception and, consequently, determine and measure the level. The Alphanumeric Display allows the user not just to enter the data for the level measurement, but even to display and isolate false echoes.
