    Application

    The general purpose 26 GHz. pulse radar level transmitter provides continuous level measurement up to 98.4'(30m)with a 4-20 mA signal output, and is configured via its integral push button display module. The non-contact liquid level sensor is intended for chemical storage or process applications in above or below grade tanks of any material. Select this sensor for challenging application conditions with corrosive media, light surface foam or agitation, higher temperature or pressure, condensation or vapor, and installation in a flange fitting. Offered in two antenna sizes, select the appropriate size based upon the desired beam angle, available mounting port size and process condition. The longer the antenna, the narrower the beam width and stronger the RF signal output for more challenging processes.
