Description
MAIN FEATURES
SLR are radar level sensors without contact with the surface whose the distance it’s measured. The transducer consists of a high frequency microwaves system able to transmit in air a train of pulses and to receive the response eco of them; the delay of this response depends on the distance that divide the sensor from the surface to measure.
Using specific algorithms, the sensor can calculate the distance and give it back as a linearized electrical signal independently from environmental conditions where the sensor works. In fact the microwaves technology is not affected by the air temperature changes and by the wind fluctuations and gusts. The SLR hydrometer requires a low continuous voltage power supply and his current consumption is very small; furthermore the SLR has the function of auto-sleeping that allow to use it in hydro-meteorological stations powered by small photovoltaic panels. The sensor is available in the version 4…20mA analog output with two wires connection (other outputs on request).
