Level Sensors

LRS radar sensors from TURCK measure level, distance, and volume noncontact in tanks and silos up to 10 m. They provide stable readings even in the presence of dust, wind, incident light, or interfering reflections—when optical or ultrasonic methods reach their limits. IO-Link, intelligent analysis functions, and the TURCK Radar Monitor simplify alignment, parameterization, and diagnostics. IP67/IP69K protection ratings support demanding industrial environments. Users benefit from fast commissioning and reliable level monitoring.

For which applications is this product family particularly well-suited?

• Continuous level measurement in tanks, silos, and containers
• Volume and distance output for different tank geometries
• Applications involving dust, wind, light, or distracting reflections

LUS ultrasonic level sensors from TURCK measure liquid levels in small and medium-sized tanks without physical contact and provide distance, level, or volume in absolute values as well as percentages. Tank geometries can be stored via IO-Link; decentralized signal preprocessing turns the devices into smart data providers. Models with a range of 40 or 130 cm and process connections of G ¾ or NPT ¾, respectively, support flexible integration. Users benefit from simple touchscreen operation and reliable tank monitoring at pressures ranging from 0.5 to 5 bar.

For which applications is this product family particularly well-suited?

• Continuously monitor the fill levels of small and medium-sized tanks
• Display distance, level, or volume in absolute values and as percentages
• Integrate machine and equipment tanks with standard process connections

NCLS limit level sensors from TURCK monitor liquids, viscous media, powders, and granules in direct contact with the media. Their hygienic design, PEEK sensor cap, and IP67/IP69K protection ratings allow for use in tanks and piping, as well as high-pressure cleaning. The switching signals remain stable even when the sensor is fully submerged, contaminated, or has media adhering to it. Two separately configurable outputs and IO-Link allow for the differentiation of various media. Users benefit from reliable level detection in food, beverage, and pharmaceutical processes.

For which applications is this product family particularly well-suited?

• Monitoring liquid levels in tanks and pipelines that come into direct contact with the fluid
• Distinguish between liquid, viscous, granular, or powdered substances
• Ensuring hygienic food, beverage, and pharmaceutical processes with high-pressure cleaning

QS18-based level sensing solutions from TURCK and Banner Engineering use optical detection to monitor level thresholds—even with transparent liquids and in tight or harsh installation environments. Plastic or glass fibers with matching probe tips enable non-contact or in-contact detection. IO-Link-capable base units and digital or analog outputs simplify integration and diagnostics. Chemical-resistant PTFE light guides and special designs for vacuum applications expand the range of possible applications.

For which applications is this product family particularly well-suited? 

• Optical detection of the levels of transparent liquids
• Monitoring liquid levels in confined, harsh, or hard-to-reach areas
• Solutions for chemical and vacuum applications using specialized glass or PTFE optical fibers

LS-5 level sensors from TURCK use guided microwave technology for continuous measurement and level detection in virtually all liquids. The TDR technology operates without moving parts and remains reliable even in the presence of foam, deposits, or changing media properties. Cuttable rod probes cover lengths from 200 to 2000 mm, while cable probes reach up to 4000 mm. IO-Link, analog output, and multiple switching points simplify integration and control. IP67 protection, a media temperature of up to 100 °C, and a process pressure of 10 bar ensure reliable performance in harsh plant conditions.

For which applications is this product family particularly well-suited? 

• Monitoring continuous level and limit values in liquid tanks
• Monitor applications involving foam, deposits, or changing media properties
• Flexibly equip metal containers—and, with coaxial tubing, plastic containers as well

TURCK’s LTX linear-travel level sensors use a magnetostrictive float to measure liquid level and provide precise, continuous position values. Pressure-resistant rod and cable versions enable measurement depths of up to 14 m and are suitable for tanks in chemical, oil, and industrial plants. IP68 protection and high resistance to chemicals and oils ensure reliable performance under harsh process conditions. Analog and digital interfaces simplify integration. Users benefit from low-wear measurement and reliable inventory monitoring.

For which applications is this product family particularly well-suited? 

• Continuous level measurement in deep tanks and containers
• Level monitoring in chemical, oil, and industrial applications
• Stock and process monitoring at high sampling depths

TURCK’s WIM linear-travel level sensors detect magnetically actuated positions noncontact and wear-free. When used in connection with a magnetic float or positioning element, they are suitable for compact level and float measurements up to 200 mm. Short blind zones, high repeatability, and robust analog outputs facilitate easy integration into flow meters, small tanks, and machine modules. Users benefit from economic, precise measurement in confined spaces and reliable process feedback.

For which applications is this product family particularly well-suited? 

• Detecting floats in flow meters
• Monitor the level using a magnetic float or positioning element
• Compact position and level measurement in small containers and machine modules
