Characteristic
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
Application
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.
Benefits
- 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
