Endress+Hauser Nivotester FTR471 Microwave Level Switch 208440-0000

The Endress+Hauser Nivotester FTR471 is a compact microwave level switch designed for reliable non-contact level detection in solids and liquids, particularly in challenging industrial environments such as silos, tanks, and hoppers. Utilizing microwave barrier technology, it operates by emitting and receiving microwave signals between a transmitter and receiver, detecting material presence when the signal is interrupted. This makes it ideal for applications in food processing, chemicals, mining, and wastewater treatment where traditional contact-based sensors may fail due to buildup, abrasion, or extreme conditions. Key features include adjustable sensitivity, fail-safe operation, and easy integration with control systems via relay outputs. Advantages over similar products include its robustness against dust, foam, and vapors, with no moving parts for low maintenance and high durability. Drawbacks may include higher initial cost compared to basic float switches and the need for proper alignment in installation. The unit supports a wide temperature range and is certified for hazardous areas, offering superior accuracy and reliability for continuous or point level measurement. This model (208440-0000) is new in box, ensuring optimal performance out of the package.
