The GUL69 intrinsically safe mining radar level sensor is a high-frequency microwave pulse instrument. A horn antenna focuses the beam so it reflects from the material surface. The antenna transmits a narrow microwave pulse downward; the echo returns to the antenna and the electronics convert it into a level signal. Because the wave travels at the speed of light, the measurement is effectively instantaneous. It is used for level measurement and control in underground and surface coal bunkers and in silos holding liquids or solids.
