VEGAFLEX 86
TDR sensor for continuous level and interface measurement of liquids
For the most extreme process conditions
Application area
Cable, rod or coaxial sensor. Its robust, mechanical design and the second process seal, the Second Line of Defense, protect the sensor for demanding measurement tasks. Process temperature: -196 … 450° C; process pressure: -1 … 400 bar
The VEGAFLEX 86 level sensor measures maintenance-free all liquids under extreme pressure and temperature conditions. Even in applications with buildup, foam generation and condensation, the sensor delivers precise and reliable measured values. In saturated steam applications, a special reference probe ensures a density-independent measurement. The VEGAFLEX 86 offers an economical level and interface measurement for your application.
Your benefit
- The guided adjustment enables a simple, time-saving and reliable setup
- Shortenable probes offer a simple standardisation and highest flexibility in the planning
- Comprehensive diagnostic possibilities ensure a maintenance-free operation and hence a high plant availability
