The ABB 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.

ABB brings laser level transmitters to the next level of non-contact measurements by packaging laser ranging technology with the required features for industrial applications.

Using a pulsed laser to perform time of flight measurement, the ABB LLT100 provides accurate distance measurements while being powered from the 4-20mA loop.

Available in aluminium 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.
