Chengdu, China – 2025-12-09 – Meskernel, a global leader in industrial laser distance sensor and ToF measurement technology, today officially announced the release of its LDL-T iToF Laser Distance Sensor—an advanced non-contact height and level measurement module designed for grain silos, feed mills, warehouses, and automated industrial environments requiring millimeter-level accuracy.
The LDL-T utilizes indirect Time-of-Flight (iToF) phase-shift laser measurement, delivering high-precision readings from 0.03 m to 60 m. It supports millimeter-level accuracy at ±(1 mm + D/10000) and operates reliably on low-reflectivity surfaces (0.2–1.0) such as corn, wheat, rice, feed pellets, and powder materials. This makes the LDL-T an ideal choice for bulk material level monitoring in harsh environments where dust, humidity, and fluctuating light have traditionally challenged ultrasonic or mechanical height detection systems.
Advanced ToF Laser Measurement Designed for Challenging Grain Environments
Unlike ultrasonic or radar sensors, the LDL-T’s iToF phase-shift method directly analyzes the modulation phase difference between emitted and returned laser signals. This provides:
- Higher accuracy on uneven grain surfaces
- More stable outputs under high-dust or low-light silo conditions
- Faster responsiveness for real-time level monitoring
- Superior repeatability for long-term automated storage management
The sensor’s automatic measurement mode intelligently adjusts refresh speed and internal gain based on signal strength, ensuring consistent distance measurement even during continuous grain inflow, vibration, dust lifting, or silo aeration.
Meskernel’s optical filtering design and proprietary anti-interference algorithms further enable the LDL-T to operate in environments where reflectivity varies widely—one of the most critical challenges in agricultural level monitoring.
Technical Specifications
Measurement Range: 0.03 m – 60 m
Accuracy: ±(1 mm + D/10000)
Reflectivity: 0.2–1.0 (supports grain, powder, feed, wood, walls)
Measurement Principle: Indirect ToF (iToF) phase-shift
Interfaces: UART, RS232, RS485
Design: Compact, low-power, suitable for embedded industrial systems
Use Mode: Single measurement / continuous measurement (auto-adaptive)
These parameters enable the LDL-T to outperform traditional grain height detectors, particularly in environments that require both precision and long-term stability.
Solving Critical Pain Points in Grain Storage & Level Monitoring
Meskernel designed the LDL-T to address long-standing challenges in grain storage facilities:
- Dust interference: Laser filtration reduces noise in dusty silos
- Low reflectivity: Stable detection on dark-colored grains and mixed material surfaces
- Uneven pile geometry: Accurate distance reading on irregular grain slopes
- Manual measurement hazards: Eliminates the need for workers to climb silo ladders
- Ultrasonic drift: Avoids temperature/humidity drift common in ultrasonic sensors
- Mechanical probe failures: No wear, no need for maintenance, no jamming issues
The LDL-T thus offers a modern, safe, and highly reliable alternative for feed mills, granaries, and agricultural automation integrators.
Versatile Applications Across Agriculture & Industrial Measurement
As a compact laser height detector and distance measurement module, the LDL-T fits a wide range of use cases:
- Grain silo height detection & real-time level monitoring
- Feed mill ingredient silo measurement
- Warehouse pile height and material stockpile monitoring
- Industrial conveyor distance measurement
- Robotics and AGV navigation height sensing
- General non-contact length/distance detection for automation
- Agriculture IoT systems requiring remote visualized storage data
The sensor integrates seamlessly with PLCs, SCADA dashboards, IoT gateways, and cloud-based monitoring platforms through UART, RS232, and RS485.
Executive Statement
“The LDL-T represents a major advancement in ToF-based laser distance measurement for grain management and industrial level monitoring,” said Andy Song, Product Director at Meskernel.
“By combining millimeter-level accuracy with a robust iToF measurement engine, we provide customers with a reliable, maintenance-free alternative to ultrasonic and mechanical sensing technologies—critical for modern, automated grain storage systems.”
Rising Demand for Intelligent Grain Storage & Non-Contact Measurement
The global shift toward digital agriculture and automated storage is accelerating the adoption of precision laser distance sensors. Traditional height detection methods often struggle with:
- Dust and humidity in silos
- Irregular grain surfaces
- Safety risks associated with manual inspection
- Increasing requirements for real-time inventory data
Industry analysts expect non-contact ToF sensor adoption to grow significantly as grain safety regulations tighten and smart agricultural facilities expand worldwide.
Meskernel’s LDL-T is positioned at the center of this transformation, offering a stable, scalable measurement platform for both new installations and modernization projects.
