Electronic level and temperature sensor

LT8023

LT0472B-B-00KSPKG/US

  • Reliable level detection in containers and tanks
  • For use in water, oils and coolants
  • User-friendly setting of switching function and switch points
  • Level and temperature monitoring with just one unit
  • Clearly visible numerical display
  • Convenient operation via buttons or parameter setting via IO-Link
For 8-wire cordsets the core colors are not standardized. Please note the wiring of the sensor and the cordsets (see data sheet).
