Characteristic
Cable, rod or coaxial sensor. Even in applications with steam, buildup, foam or condensation, the sensor delivers precise and reliable readings – also in standpipes or bypass pipes.
Application
The VEGAFLEX 81 level sensor measures maintenance-free all kind of liquids. Even in applications with vapour, buildup, foam generation and condensation, the sensor delivers precise and reliable measured values. The VEGAFLEX 81 is the economical solution for various level and interface measurements.
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
