JTR Series Guided Wave Radar Level Transmitter

The JTR series is a guided wave radar level transmitter using TDR technology to generate a continuously changing 4-20mA signal representing measured level for liquids, bulk solids and slurry materials in a wide range of industries and applications.  It is cost effective and very reliable.

Product Description

The JTR30 series is a guided wave radar level transmitter that uses state-of-the-art TDR (time domain reflectometry) technology to accurately measure and transmit the level of liquid, bulk solids and slurry materials.  The JTR provides a 4-20mA output indicating material level, is equipped with keypad/display and can also be equipped to provide HART communications output.
