The intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 65.6’ (20m) with a 4-20 mA analog and HART digital signal output, and is configured via its integral push button display module or HART communicator. 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 process conditions with corrosive media, light surface foam or agitation, higher temperature or pressure, condensation or vapor, and installation in a flange fitting. Typical applications include bulk storage and process tanks.
Sufuric and nitric acids are strong mineral acids that are widely used in industrial and commercial applications. Highly vaporous and corrosive, they’re difficult to measure and harsh on equipment. The non-contact LR21 is an excellent choice for this media, as its 26 GHz. pulse radar measurement is unaffected by extreme vapor, and the antenna’s PTFE inner shield, provides reliable corrosion resistance.
