Tracer 1000™ LTT1-2G 2nd (up to 80ft) Radar Level Transmitter

 Tracer 1000™ LTT1-2G 2nd Generation Radar Level Transmitter (up to 80ft) 

Tracer 1000™ LTT1-2G 2nd Generation Radar Level Transmitter (up to 80ft)

Featuring TDR (Time Domain Reflectometry) technology, the Tracer 1000™ second-generation Guided Wave Radar level transmitter provides continuous level measurement in liquids, solids, and slurries. This innovative device has almost no installation restrictions in tanks, silo, and bins up to 80 feet. The Tracer 1000™ 2G has a fully isolated 4-20 mA output that can be scaled for tank level or distance. The unit requires 18 to 30 VDC power.

The 4-wire device comes standard with an RS-485 COMMS output that can be connected to the Tracer Talker™ software for custom configurations and detailed level processing analysis. The Tracer 1000™ 2G ships pre-calibrated precisely for the customer’s application for quick installation and setup. If adjustment is needed in the field the RS485 Communication Tool and Tracer Talker™ software is recommended. TDR technology is not affected by pressure, vacuum, temperature, viscosity, foam, or dust. Changes in dielectric constant or coating of the probe do not affect the level measurement due to the dynamic sensing technology programmed into the artificial intelligence of the Tracer 1000™ 2G GWR level transmitter
