    Application

    The intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 229.7’ (70m) with a 4-20 mA analog and HART digital signal output, and is configured via its integral push button display module or WebCal software. The non-contact solids level sensor is intended for dry solid media including aggregates, grains, pellets, powders and building materials. Select this sensor for the most difficult process conditions with significant to extreme dust and installation with an adjustable gimbal flange. For ease of installation, the parabolic antenna can be unclamped, inserted through the base of a riser, and reattached to the sensor. Typical applications include silos.
