TLR1000G1 Guided Wave Radar Level Transmitter

TLR1000G1

TLR1000G1 guided wave radar level transmitter measures continuous level in conductive and non-conductive liquid applications using TDR technology. It guides high-frequency microwave impulses along a steel cable, rod or coaxial probe and calculates level from pulse travel time. Also, it supports 4–20 mA / HART output, two-wire or four-wire versions, IP67 protection and measuring ranges up to 30 m depending on probe type. As a result, it suits liquid level applications where steam, buildup, foam or condensation may affect simpler measurement technologies.
