Continuous level sensor (guided wave radar)
LR8020
LR0000--BR34ASPKG/US
- For the reliable level control in tanks and containers
- Suitable for water, oils and coolants
- Modular system consisting of evaluation unit and probe
- Probes may be cut to length for application flexibility
- User-friendly communication and parameterization via IO-Link
For high process temperatures: The temperature at the process connection is decisive. The actual medium temperature may be higher.
For 8-wire cordsets the core colors are not standardized. Please note the wiring of the sensor and the cordsets (see data sheet). Please see the technical note under "Downloads"
