Leuze Sensor DMU230-6000/LV-M12 Ultrasonic distance sensor

Description

The Leuze Sensor DMU230-6000/LV-M12 is a powerful, long-range ultrasonic sensor designed for demanding distance measurement and object detection tasks in expansive industrial environments. It utilizes robust ultrasonic echo-sounding technology to deliver accurate measurements up to 6000 mm, independent of the target’s material, color, or surface characteristics. The sensor is built into a durable, cylindrical housing rated IP67 for reliable operation in dusty, humid, or wet conditions. Equipped with a standard 4-pin M12 connector, it ensures easy integration into automated systems. With configurable analog and switching outputs, high environmental immunity, and a wide operating temperature range, the DMU230-6000/LV-M12 provides a versatile and dependable solution for monitoring large-scale processes, from silo level control to vehicle positioning.

Features

Extended 6-Meter Measuring Range: Capable of monitoring large distances, making it ideal for high bins, deep tanks, and large machinery.
Robust Construction & High IP Rating: The IP67-protected housing ensures reliable performance outdoors and in harsh industrial settings exposed to dust, moisture, and washdown.
Dual Output Flexibility: Provides both a continuous analog output for precise level/distance monitoring and programmable switching outputs for alarm functions or limit value control.
Advanced Signal Processing: Incorporates intelligent echo processing and temperature compensation to filter out false echoes from fixed installations (e.g., ladders, beams) and maintain accuracy despite ambient temperature changes.
Easy Configuration via Teach-In: Simple push-button or remote input teach-in function allows for quick setup of measuring windows and switching points without a configuration tool.
Material-Independent Operation: Reliably detects solid, liquid, granulate, or powdered materials regardless of surface color or reflectivity.

Applications

Bulk Solid Level Measurement: Continuous level monitoring in large silos, hoppers, and storage bins for grains, plastics, cement, or other bulk materials.
Liquid Level in Large Tanks: Monitoring fill levels in water treatment tanks, chemical storage vessels, and process tanks.
Vehicle Positioning & Guidance: Distance control for automated guided vehicles (AGVs), cranes, and forklifts in warehouses and logistics centers.
Large Object Detection: Presence detection and position verification of large pallets, containers, or machinery parts.
Waste Management: Fill level measurement in waste compactors, recycling containers, and skip bins.
