MWF MICROWAVE LEVEL TRANSMITTER MWF 21 / MWF 27 WITH GUIDED WAVE RADAR

PRODUCT DESCRIPTION

Continuous level measurement with guided wave radar
The devices of the MOLOSwave series for continuous level measurement are working with the Time Domain Reflectometry (TDR) measurement principle. They are specifically designed for the use in bulk goods. During the measurement high frequency microwave pulses with low energy are coupled onto the probe and guided along this probe to the bulk goods. The product surface partly reflects these pulses. The electronic detects the reflected pulses and calculates the actual filling level from the time difference of the transmitted and received signals. These filling levels are made available as a 4-20 mA signal for further signal processing. This signal can be visualized with easy to use and well legible indicating units that are mounted in a switch cabinet.
