LTR01 Guided Wave Radar Level Transducer

Brand: Intempco Controls, Inc.

Featuring TDR (Time Domain Reflectometry) technology, the LTR01 Guided Wave Radar level transmitter provides continuous level measurement in liquids, slurries, and solids up to 65 feet with isolated Analog output.

This innovative device has almost no installation restrictions - it can be mounted in small tanks, tall and narrow nozzles and it measures precisely even with difficult tank geometries or close to interfering structures.

The LTR01 is ideal for various types of processing and storage applications and has an exceptional performance in liquids with low reflectivity such as oils and hydrocarbons.

TDR technology is not affected by pressure, temperature, viscosity, vacuum, foam, and dust changes in dielectric constant or coating of the probe.

The LTR01 can measure virtually any product with a dielectric constant greater than 1.3.

The LTR01 ships pre-calibrated precisely for the customer’s application for quick installation and setup.

If the customer chooses to calibrate on their own in the field, the LTR01 settings may be configured via RS-485 Modbus communicator and its software.
