Senator S24L FMCW 24GHz Radar for Liquids

Senator S24L FMCW 24GHz Radar for Liquids

The Senator S24L FMCW 24GHz Radar Level Transmitter is designed specifically to measure liquids in basic process applications. This device is a non-contact radar level transmitter that uses FMCW technology. It measures distance, level, and volume of liquids and pastes. It is a market-entry transmitter that provides accurate readings in closed tanks, in the open air like rivers or dams, and even in fast-moving processes.

Principle of Operation

Frequency Modulated Continuous Wave (FMCW) technology features a continuous signal transmission, providing immediate measurement updates with zero delays. Unlike pulse radar, where the transmitter sends a pulse and then stop and waits for a reflection - FMCW radar emits a continuous signal. It determines the distance to the target by measuring the frequency difference between the emitted and the reflected signals. This frequency change is also called the "Doppler Shift" of the returned signal.
