The IFM LR2050 is a guided wave radar level sensor designed for reliable continuous level measurement in tanks and containers. It supports probe lengths from 150 to 2000 mm and uses a G3/4 external threaded process connection. The sensor provides one digital output and one 4...20 mA analogue output. A clearly visible four-digit LED display provides local level information. It is suitable for water, hydrous media, oils, and oil-based media.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The LR2050 uses guided wave radar to measure the level of liquids. The active range extends to L-40 mm for standard media. For oils and oil-based media, the active range is reduced according to the specified installation conditions. A 1 mm resolution provides detailed measurement information. This makes the sensor suitable for continuous process monitoring.
The LR2050 provides one 4...20 mA analogue output for continuous level transmission. One digital output can be configured for switching control. The output configuration allows the sensor to provide both measurement and limit information. This simplifies connection to PLC and process-control systems. The analogue signal is suitable for standard industrial controllers.
A four-digit alphanumeric display provides local level indication and parameter information. The G3/4 external thread provides process installation. Gold-plated M12 contacts provide the electrical connection. The stainless-steel process materials support industrial use. The sensor is designed for tank and container level control.

The 4...20 mA output allows the measured level to be transferred continuously to a controller. The digital output can provide an independent switching signal. This combination reduces the need for multiple sensors. The four-digit display provides local visibility. This makes the LR2050 suitable for automated process control.
The probe can be selected from 150 to 2000 mm. The probe length can therefore be matched to the vessel height. The G3/4 process connection supports standard industrial installation. The sensor is designed for water, hydrous media, oils, and oil-based media. This gives the LR2050 broad process-level monitoring capability.
