OPTIFLEX 3200 Guided radar (TDR) level transmitter – Version with single rod

The OPTIFLEX 3200 is a 2-wire guided radar level transmitter based on the Time Domain Reflectometry (TDR) technology. It is designed for the measurement of level and interface in the food, beverage and pharmaceutical industry. The TDR is insensitive to steam, foam or condensation and suitable for a large variety of liquids with hygienic requirements. The wetted parts have a gap-free hygienic design that ensures simple and reliable cleanability (CIP/SIP). Dedicated industry-specific probes and process connections as well as various converter and electronic versions are available to suit every installation and facilitate device access.
