ABB Laser Level Transmitter LLT100
Level Measurement Revolution
Lasers have changed the world of level measurement, offering many benefits over traditional non-contact instruments. With its narrow laser beam, the LLT100 can avoid obstructions and be installed near vessel walls or in tanks with blades, grates or grids. The laser transmitter measures continuously, providing rapid surface change tracking. Advanced signal processing delivers reliable measurements, even in the presence of mixers and dusty, foggy, limited environments. In industries where accuracy and reliable level measurement is crucial, the rugged LLT100 will become a valuable member of your team.

LLT100 KEY FEATURES
Laser Design
The LLT100 utilizes an eye safe, Class 1 laser beam. The beam angle is 0.3-degrees, providing accurate level measurement in narrow or crowed vessels. This allows users to install the transmitter outside of the process, away from hazardous zones, areas prone to flooding, or mechanical devices.
High Accuracy
With a resolution of 5 mm (0.2-in) and typical accuracy of +/-11mm (0.4-in), the LLT100 provides highly accurate and repeatable measurements, often with better resolution and precision than traditional methods.
Wide Measurement Range
Measures 2-ft to 100-ft for liquids, 2-ft to 330-ft for solids, and 2-ft to 660-ft for positioning applications, making it suitable for a wide range of vessel sizes.
Digital Signal Processing
Besides providing a single output for level, the LLT100 can transmit additional variables. These device variables can help with predictive maintenance and provide confidence in level measurement.
Hazardous Area Approvals
Available with approvals of CE, ATEX, IECEx, FM, 3A for use in hazardous areas, such as dusty or explosive atmospheres.

LLT100 KEY BENEFITS
Reduced Maintenance
Because it operates without any physical contact with the measured material, there is no wear or tear on the sensor, eliminating the need for frequent cleaning compared to older instruments exposed to the process.
Increased Safety
Unlike other sensors, the LLT100 can be positioned above processes, providing increased safety and easy access. And due to its narrow laser beam, it can measure all the way to the bottom of a well even in the presence of internal structures.
Versatility
Measures levels of various materials, including liquids, slurries, powders and bulk solids, regardless of their dielectric properties or density.
Ease of Installation
Can be installed without shutting down the process or emptying the vessel, as it can be mounted on the top or side of the vessel without intrusion.
Longer Operating Life
With no direct exposure to the process material, the LLT100 has a longer operating life than traditional instruments, reducing the need for frequent replacements.
