LEVEL TRANSMITTERS

GENERAL DESCRIPTION The MicroTREK Guided Wave Radar level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. MicroTREK level gauge operates based on the well-known TDR (Time Domain Reflectometry) principle. Micropulses are sent along a probe guide at the speed of light. As soon as the impulse reaches the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the impulse. The reflected signal is dependent on the dielectric constant of the material, the...

mvELcn INSTALLATION WIRING Display module connector Except the plastic coated and the coax types the probes can be removed from the head unit by the user. s = minimum distance from the internal disturbing objects. Objects that are parallel to probe do not disturb the measurement. Mono Probe s > 300 mm h < d Twin Probe s > 100 mm t = upper dead-zone Coaxial Probe s = 0 mm b = lower dead-zone SETUP, PROGRAMMING with SAP-300 display unit With the help of the SAP-300 plug-in display a simplified programming can be accomplished which covers most of the applications. The basic parameters of...
