Measuring Principle - An electromagnetic pulse is transmitted from the ABM sensor. The pulse 5.8 - 26 GHz carrier Frequency travels to the surface being monitored and is reflected off this surface back to the sensor face. The time of flight is divided in half, and converted to an output current directly proportional to the material level. In case of low dielectric materials ( r < 10), electromagnetic wave penetrates materials. In this case ―Low Dielectric Material‖ has to be on. The ABM radar is a one echo sensor, it adjusts its power and sensitivity to receive one echo from measured material and to eliminate any false echoes. This feature gives radar extremely narrow radiation beam (like a laser)
