Emerson Rosemount 3144S field temperature transmitter, RTD and thermocouple, HART, drift diagnostics

The Rosemount 3144S is a field temperature transmitter for RTDs and thermocouples with sensor drift and open-circuit diagnostics. It is used on critical loops where long-term stability and early detection of sensor degradation matter.

A backup input (Hot Backup, optional) allows switching to a second sensor. The device is part of one ecosystem with 3051 transmitters and AMS software. Protocol, SIL certification and hazardous area approvals depend on the version code.

Key features:

• Inputs for RTDs and thermocouples
• Sensor drift and open-circuit diagnostics
• Optional Hot Backup input
• One ecosystem with 3051 and AMS

Specifications:

• Inputs: RTDs and thermocouples
• Diagnostics: drift, open circuit, optional Hot Backup
• Mounting: field housing
• Protocol: HART and others by code
• Sensor: ordered separately
• Certifications: SIL and hazardous area approvals by version

Application: Reactors, columns, furnaces, heat exchangers, SIP/CIP lines.

Before ordering: The sensing element and thermowell are separate order items. Supplied to order by model code; specify the sensor type, protocol and required hazardous area approval.
