Emerson Rosemount 1151DP5E12M1 Pressure Transmitter

Emerson Rosemount 1151DP5E12M1 Pressure Transmitter is a differential‑pressure transmitter in the legacy Rosemount 1151 family, designed to convert the pressure differential between two process ports into an electrical signal for process control. The model is documented and sold under the Rosemount 1151DP line, and Emerson classifies the 1151 family as obsolete, directing users to consult a local Emerson representative for current measurement options. As part of the 1151 differential‑pressure transmitter family, the DP configuration codes describe devices intended for differential pressure sensing in industrial processes; historically, the 1151 family includes configurations with an analog output in a 4–20 mA current loop for certain DP ranges. The exact part number 1151DP5E12M1 is listed by retailers such as Zoro and on other catalog sites, confirming the model designation without altering its documented status. Given its age and Emerson’s obsolescence notice, customers commonly evaluate newer Rosemount transmitters (notably the 3051 family) for ongoing support, compatibility, and availability.
