Description
VEGAFLEX 81
4 … 20 mA/HART – two-wire
TDR sensor for continuous level and interface measurement of liquids
Application area:
With VEGAFLEX 81 you can measure all kinds of liquids essentially
maintenance free. The sensor delivers precise and reliable measured
values even in applications with steam, buildup, foam generation or
condensation. VEGAFLEX 81 is a truly cost-effective level and interface
sensor for your measuring task.
Your benefit:
- The guided adjustment enables a simple, time-saving and reliable
setup - Comprehensive diagnosis options ensure maintenance-friendly
operation and thus high plant availability - Shortenable probes allow simple standardization and maximum
flexibility in planning
Function:
High frequency microwave pulses are coupled onto a cable or rod and
guided along the probe. The pulse is reflected by the product surface.
The time from emission to reception of the signals is proportional to
the level in the vessel.
