Featuring TDR (Time Domain Reflectometry) technology, the Tek-Flex 4100A Explosion Proof Guided Wave Radar Level Transmitter provides continuous level measurement in liquids, solids, and slurries. This innovative device has almost no installation restrictions in tanks, silos, and bins up to 65 feet in height. The Tek-Flex 4100A 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 Tek-Flex 4100A is shipped precisely pre-calibrated for the customer’s application and thus ensures quick installation and setup. TDR technology is not affected by pressure, vacuum, temperature, viscosity, foam, or dust. Changes in dielectric constants or coating of the probe do not affect the level measurement, due to the dynamic sensing technology programmed into the artificial intelligence of the Tek-Flex 4100A level transmitter.
