1. General Introduction
ABB LLT100 is a laser level transmitter 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 and gas, chemicals, food and beverages, power,pulp and paper, pharmaceuticals, and water and waste water.measuring levels of solids at up to 100 m (328 ft),and liquids at up to 30 m (98 ft) when the process is at normal pressures.The Hygienic model is ideal for food and beverage or pharmaceutical applications.
