Cảm biến radar đo mức chất lỏng liên tục VEGAFLEX 81 Vega trong môi trường có hơi nước, ngưng tụ, bọt và tích tụ.

VEGAFLEX 81

TDR sensor for continuous level and interface measurement of liquids

Universal TDR sensor for liquids of all kinds

 

Application area

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.

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.

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
