Continuous level sensor (guided wave radar)
LR2050
LR0000B-ER34AKSKG/US
- For the reliable level control in tanks and containers
- Suitable for water, oils and coolants
- Clearly visible numerical display
- Modular system consisting of evaluation unit and probe
- Probes may be cut to length for application flexibility
- Convenient operation via buttons or parameter setting via IO-Link
For high process temperatures: The temperature at the process connection is decisive. The actual medium temperature may be higher.
