IO-Link Radar Sensors for Level Measurement


Turck’s LRS510 sensor family offers extensive analysis functions for challenging level applications in tanks and silos.

The IO-Link-capable radar sensors of the LRS Series complete Turck’s portfolio for level measurement in the 0.35 to 10 meter range. The devices with protection to IP67/69K are especially recommended for level applications in factory automation, for which optical or ultrasonic sensors are unsuitable due to factors such as dust, wind or light. The freely radiating LRS radar sensors also offer detailed analysis functions which were previously only possible in the high-end radar sensors used in the process industry. The absence of a metal guide probe enables the sensor to be used easily in hygiene applications and simplifies commissioning.  

The touchpad of the LRS series with capacitive buttons and a translucent front cap is based on the same concept as Turck’s Fluid 2.0 sensor platform, and enables the output of distance, level and volume values. The LRS sensors are available either with two switching outputs or with one switching and one analog output. Thanks to their additional IO-Link interface and intelligent decentralised signal preprocessing, all variants provide a large quantity of additional information for processing in condition monitoring applications in IIoT: besides signal strength, this includes temperature values, operating hours or switching cycles.  

Users of Turck’s IO-Link master can call up the Radar Monitor via the IODD configurator without any additional software. The browser-based configuration tool graphically displays the measurement curve of the sensor and offers plain text access to all relevant parameters. This makes it possible for example to mask out the interference signal of an agitator or grid, or to perfectly align with the real-time feedback of the sensor in order to maximise the reliability of level measurement in challenging applications.
