Anderson-Negele L3 Pressure and Level Transmitter

The Anderson-Negele L3 Pressure and Level Transmitter is designed to measure process pressure or hydrostatic level in sanitary process applications. The state-of-the-art temperature compensation reduces errors associated with process temperature changes with improved zero stability reduces sensor interaction. 

The graphical user interface makes set-up and programming easy by directly aligning to the HART™ DD menu structure. The field repairable and reconfigurable design allows the user to change the display orientation, add a remote cable, or replace a component in the field without impact to accuracy. 

The L3 incorporates everything the Anderson-Negele team has learned about pressure and pressure based level monitoring over the last 32 years. 

Features

Features include a new temperature compensation strategy, which optimizes performances in hot and highly dynamic systems. This new feature results in fewer errors in brewing, fluid food, and hot fill applications. The L3 has an easy-to-use graphical display interface, which reduces reliance on a manual during start-up and commissioning.

The L3 also has the ability to use the same platform for line pressure or hydrostatic level applications. This reduces stocking needs for our customers and eliminates the need to learn multiple platforms. The modular design allows for repair and reconfiguration on the customer's site and includes the ability to add a remote cable to the assembly. This considerably reduces cost of ownership.
