Level Transmitters : LU30
EchoTouch® Ultrasonic Level Transmitter
Application
The general purpose 3-wire ultrasonic level transmitter provides continuous level measurement up to 24.5' (7.4m) with a 4-20 mA signal output, and is configured via the integral push button display module. The level sensor has one 10A relay which can be configured on a single set point (high level alarm or low level alarm) or latched on two set points for automatic fill or empty with fail-safe logic. This non-contact liquid level sensor is well suited for corrosive, ultrapure, sticky or dirty liquids, and is widely selected for bulk storage and day tank level applications.
Features
Level measurement up to 24.5' (7.4m) with 1 programmable relay
Configuration is simple via integral push button display module
LED digital display indicates level in inches or centimeters
Programmable relay for alarm or automatic fill-empty control
Polypropylene enclosure rated NEMA 4X with rugged PVDF transducer
