The new standard in industrial laser level transmitters
Measurement made easy

Customer benefits
The LLT100 is specifically made for industrial applications and
harsh environments. It provides continuous, non-contact level
measurement capabilities for process automation and
inventory management in industries such as mining,
aggregates, oil & gas, chemicals, food & beverages, power,
pulp & paper, pharma, and water & waste water.

Optimize process or inventory management

Precise measurement of any solid or liquid
Independent of material properties

Low cost of ownership

Fast and flexible installation
No maintenance
Single product configuration works for many applications

Fast delivery

Less than 2 weeks from order to receipt

Main features

ABB brings laser level transmitters to the next level of
noncontact measurements by packaging laser ranging
technology with the required features for industrial
applications. Using a pulsed laser for performing time of flight
measurement, LLT100 provides accurate distance
measurements while being powered from the 4 to 20 mA
loop. Available in aluminum or stainless steel body, it comes
with a variety of process interfaces. It can meet the demands
of hazardous area locations, high pressure and high
temperature applications.
