The OPTIFLEX 6200 is a 2-wire guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. It is designed for the level measurement of solids in bulk storage and other silos up to a height of 40 m / 131.2 ft. The single rod or single cable probes withstand high traction loads, making the level transmitter suitable for use in a wide range of applications with solids of different grain sizes – from fly ash and cement to gypsum and plastic granulates to tobacco and starch. This guided radar is equally suitable for applications involving milk, sugar, chocolate or coffee powder.
