Precise Beam Aiming
Direct the narrow beam with up to 10° flexibility toward bin outlet or vessel bottom with an adjustable mounting flange.
Narrow Beam, High-Accuracy Level Measurements
LL-100 Laser Level Sensor for Low-Dust Applications
The BinMaster LL-100 laser level sensor is a non-contact device designed for continuous level measurement, plugged chute detection, and buildup monitoring in vessels up to 160 feet tall.
Its less-than-1° beam angle makes it ideal for narrow silos, constrained spaces, and applications where the signal must be aimed precisely to avoid structure, corrugation, or vessel walls.
The LL-100 is well-suited for low-dust bulk solids, pellets, granular materials, and opaque liquids. It provides fast updates, high accuracy, and precise targeting for operations that need dependable inventory control in difficult-to-reach vessels.
Why Choose the LL-100 Laser Sensor?
The LL-100 is designed for applications where a very narrow beam and precise aiming are more important than broad-beam measurement technologies.
- Measures from 1 ft. to 160 ft.
- Uses a <1° beam angle for precise targeting; ±1 inch accuracy
- Fast update rate of 8 readings per second
- Suitable for narrow vessels or tight spaces
- Can be used for level control, plugged chute detection, and buildup monitoring
- Works in low-dust solids and opaque liquid applications
- Integrates with 4–20 mA systems and can work with BinMaster connectivity options, such as LTX-100 Gateway and BinCloud® inventory software
How Laser Level Sensors Work
The LL-100 sends laser pulses toward the material surface and measures the time it takes for the reflected signal to return. That time-of-flight data is processed by the sensor’s firmware and converted into a precise distance measurement. The measured distance is then used to determine the level inside the silo, hopper, chute, or tank.
Because the beam is extremely narrow, the LL-100 can be aimed at a specific target point such as the discharge outlet, bottom of a hopper, or a clear path between internal structures. The sensor firmware also compensates for angled mounting, so the reported distance remains accurate.
The Legend in Low Dust
Best Applications for a Laser Level Sensor
Laser level measurement is best suited for applications where precise aiming is critical and where the environment is relatively clean. Often utilized for:
- Narrow or tall silos
- Vessels with internal structure
- Processes that require fast, accurate single-point measurement
- Pellet, granule, and bulk solid materials, or opaque liquids
- Low-dust installation areas
- Plugged chute detection or buildup monitoring
Typical applications include chutes, hoppers, crushers, restricted process equipment, inventory monitoring in low-dust solids storage, and liquid tanks with vapor or pressure conditions.
The LL-100 should not be used in dusty environments. BinMaster specifically positions its laser technology for low-dust vessels and bulk solids applications.
In heavy dust conditions, technologies like 80 GHz radar or 3D acoustic scanners are generally better suited.
LL-100 Features That Simplify Installation and Use
Fast, Accurate Measurement
Rapid level updates at eight readings per second; LL-100 remains accurate within ±1 inch regardless of surface angle, slope, texture, or color.
Easy Field Configuration
Set up & configure lasers via USB port. No need to empty bin. Use for powering and viewing status when field power is unavailable.
Reduced Maintenance
Integrated still-air barrier helps minimize dust interference with optics; optional air purge keeps lens clean for reliable operation.
Mounting Laser Sensors
The LL-100 can be installed through a 2.5-inch process connection or a 4-inch flange connection on the roof of a silo.
It can also be mounted inside the vessel on a bracket above the measured material.
The adjustable flange allows the installer to loosen the clamp ring, aim the sensor body at the desired point, and tighten it in place.
- Adjust angle up to 10° for precise beam aiming
- Direct the beam to the desired target point
- Swivel-style mounting accessories are also offered by BinMaster for aiming radar or laser sensors
Simple Setup and Operation
Operating Highlights of Laser Sensors
The LL-100 requires 24 VDC input power and provides a 4–20 mA output for integration into monitoring and control systems.
Full and empty parameters are set using the analog output setup and USB configuration tools, allowing the sensor to be commissioned in the field with minimal complexity.
- USB communication for setup and diagnostics
- Continuous, single-point level monitoring
- Compatible with BinMaster's remote inventory and gateway solutions, including BinCloud® software and LTX-100 Gateway
Common Industries & Materials for LL-100 Sensors

Laser Level vs. Radar Sensors
Both laser level sensors and radar level sensors provide non-contact measurement for bulk solids and liquids.
However, each technology performs best in different environments and vessel conditions. Choose laser sensors when:
- The vessel is narrow or contains internal structure
- An extremely precise beam for targeting is required
- The process environment has low dust
- Measurement point must be aimed at an outlet or target area
- High update speed and accurate single-point measurement are required
The LL-100 laser sensor’s tight beam angle allows operators to direct the measurement exactly where needed, making it ideal for confined spaces, narrow silos, crushers, and chutes.
Select the Right Technology
Laser sensors are ideal for precise targeting in clean environments, while radar sensors are better suited for dusty, extreme industrial conditions.
80 GHz radar sensors are often preferred for dusty solids storage, as radar waves penetrate dust more effectively than optical technologies.
- Use in vessels that contain heavy dust or airborne particles
- Ideal for materials that generate steam, condensation, or foam
- Continuous level measurement in harsh environments
- Well-suited for large silos where measurements must remain reliable under difficult process conditions
By offering both technologies, BinMaster helps operators select the most reliable solution for their specific application and process environment.
