Product Overview: ifm electronic LR3000
The ifm electronic LR3000 is a high-precision electronic level sensor utilizing Guided Wave Radar (TDR) technology. This sensor is specifically engineered for continuous level measurement and point level detection in industrial liquids, including oils, coolants, and water-based media. The LR3000 is a critical component for machine tool lubrication systems and hydraulic power units, providing reliable data even in the presence of foam, steam, or high turbulence.
Advanced TDR Technology and IO-Link
The LR3000 works by sending electromagnetic pulses along a probe. When these pulses hit the medium, they are reflected back. This «Time-of-Flight» principle ensures that the measurement is independent of the medium’s density or temperature fluctuations. Integrated with IO-Link communication, the LR3000 facilitates remote parameterization and detailed diagnostic monitoring, making it a future-proof solution for Industry 4.0 environments.

System Reliability and Flexibility
The modular design of the LR3000 allows for probes to be shortened or replaced easily, adapting to various tank heights. The sensor housing can be rotated 345°, and the display is customizable to show levels in mm, inch, or percentage. Its high pressure resistance and immunity to heavy deposits on the probe ensure maximum uptime in harsh manufacturing cells.
