APPLICATION

Intrinsically safe for use in hazardous locations, the ultrasonic level transmitter provides continuous level measurement up to 18’ (5.4m), and is configured via its integral push button display module. This non-contact liquid level sensor is ideally suited for corrosive, sticky or waste liquids, and is selected for bulk storage, day tank, skid or machine and process tank applications located within a classified area.

FEATURES

  • LCD digital display indicates level in inches or centimeters
  • PP enclosure rated NEMA 4X with rugged Kynar® transducer
  • EasyCal simple push button calibration for all user set points
  • Adjustable dead band and range filters eliminate false echo returns
