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
  • Adaptation to different container heights through shortening of the probe
  • User-friendly communication and parameterisation via IO-Link
For high process temperatures: The temperature at the process connection is decisive. The actual medium temperature may be higher.
For 8-pole sockets the core colours are not standardised. Please note the wiring of the sensor and the sockets (see data sheet). Please see the technical note under "Downloads"
