Rosemount 2051TA3 Transmitter

Core Performance & Industrial Application

The Emerson Rosemount 2051TA3F2B21AS1E2M5Q4Q48 is a 2051T in-line absolute pressure transmitter, range 3 (0-800 psia / 0-55 bar).

4-20 mA HART® digital output with built-in local operator interface (LOI) and configuration buttons for tool-free setup.

Reference accuracy ±0.065% of calibrated span (standard; ±0.05% with P8 high-performance option), 5-year stability option.

In-line threaded process connection (code 2B, 1/2-14 NPT female) with 316L isolating diaphragm; compact field-mount housing.

It is used as spare replacement in absolute vacuum and pressure measurement loops.
