Aplus Finetek Sensor, Inc. is pleased to announce the introduction of the JTR Series Guided Wave Radar Interface Level Transmitter. Using state-of-the-art TDR technology, the JTR continuously measures the changing level of each of two liquids of differing specific gravity, within the same tank. The JTR features a 2-wire loop power supply and provides an independent 4-20mA output for each the top and bottom fluid levels. The JTR can also be equipped with HART 7.0. Alternately the JTR can be provided in a 4-wire design when RS485 MODBUS communications is required, with either one 4-20mA output or with two 4-20mA outputs when being used for interface measurement applications. The JTR is also a very cost effective and reliable unit.
How it works …. The JTR use Time Domain Reflectometry (TDR) technology. Radar pulses are guided to the material surface and back to the JTR by a wave guide, probe, rod or cable, and the time of flight is precisely measured and directly corresponds to the empty space distance within the vessel. Most of the radar pulse energy is absorbed by the top fluid, then another reflection (echo) is created off the interface or bottom fluid, therefore in the case of interface level measurement applications two significant reflection echoes will exist, the top fluid and the interface or bottom fluid. A minimum difference in the S.G. of the fluids is necessary.
Key features of the JTR guided wave radar level transmitter include cost effective 2-wire power supply to simplify installation, optionally available HART or RS485 MODBUS digital communications, up to 100ft measuring range (probe type dependent), built-in display for easy setup, a wide range of mounting connection sizes and types and ±0.197” (5mm) measurement accuracy.
