1. General Introduction
Rosemount 3051T Pressure Transmitters is industry standard inline type for gauge and absolute pressure measurement, its in-line and compact design allows the transmitter to be connected directly to a process for quick, easy and cost effective installation. Capabilities include: 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);Safety certification (option code QT).
