Description

THE NIVOBOB® SERIES OF PLUMB BOB SENSORS FROM UWT are used for continuous level measurement in storage silos and for interface measurement in various industries. The simple electromechanical measuring method is a classic in level monitoring and suitable for almost all bulk solids, regardless of the DK value (dielectric constant). UWT offers two different series for this technology area. The products of the 3000 series are suitable for standard applications with increased requirements. With the products of the 4000 series simpler applications can be solved economically. YOUR BENEFIT • Durable, simple and reliable measuring principle up to 50 m measuring range • Integrated belt cleaner • Brushless motor for many measuring cycles in short intervals FEATURES • Two-chamber housing with electronics and mechanics compartment • 1 1/2"" process connection or flange • Socket pipe in various lengths • Integrated belt cleaner • Robust tape with rounded edges for up to 500,000 measuring cycles • Clear tape guide over two rollers • Measuring range up to 50 m • High measurement accuracy • Various feeler weights for bulk weights from 20 g / l • Suitable for process temperatures up to 250 °C • Display, menu-guided commissioning and diagnostic functions OUR SOLUTIONS FOR • Strong caking • Material with changing temperature / humidity • Measurement range of up to 50 m • Electrostatic charging • Heavy material and light solids • Limited space • Low dielectric constant • Explosive environments
