Low power consumption radar sensors designed for measurements in natural environments. They are used to monitor the level of rivers, canals, water bodies, etc... PARATRONIC CR420 level sensors are based on pulse radar technology. Their very low power consumption allows them to be used on batteries or solar panels. Self-stable, they automatically correct horizontal errors up to 10°. Their neutral colour allows them to blend in with the natural environment. Their reduced measuring cone and the absence of blind spots make them easy to install. The measuring range can vary from 6 to 30 metres depending on requirements. Parameters can be set by the user simply with the box ADP USBand the CAB USBB and the free software Sensor HMI. Depending on the version, it will provide a 4/20 mA signal on two wires, powered from 10 to 33 Vdc or an RS485 signal, powered from 9 to 20 Vdc. The different versions are IP68, delivered with 2 meters of cable (possibility of other length see CABCR). Other options available CRUZOE MOD4/20, RADAR EQUERRE.
