1. General Introduction
Rosemount 3051L Level Transmitter is a fully-integrated and SIL safety certified transmitter for level measurement, combines the performance and capabilities of Rosemount 3051 Transmitters with the reliability and quality of a direct mount seal in one model number. Rosemount 3051L Level Transmitters offer variety of process connections, configurations, and fill fluid types to meet a breadth of level applications.
Capabilities of a Rosemount 3051L Level Transmitter include: Quantify and optimize total system performance (option code QZ); Tuned-system assembly (option code S1); The Loop Integrity Diagnostic continuously monitors the electrical loop to detect changes that compromise the integrity of the transmitted 4-20 mA output signal (Option Code DA0); LOI with straightforward menus and built-in configuration buttons (option code M4).
