EchoPro® LR21 intrinsically safe 26 GHz pulse radar level transmitter provides continuous level measurement up to 65.6 ft. (20m) range with a 4-20 mA analog and Hart digital signal output. The sensor is configured by a integral push button display module or HART communicator. This non-contact liquid level sensor is for chemical storage or process applications in above grade or below grade tanks of any material. This sensor is for challenging process conditions with-corrosive media or process applications, light surface foam or agitation, higher temperatures or pressure, condensation or vapor and installation in a flange fitting. Applications include bulk storage and process tanks.
Features
- Configuration via push button display or HART communicator
- 316 Stainless steel antenna w/ PTFE inner shield for corrosive media
