Overview
The Rosemount 3144 temperature transmitter is a precision temperature measurement device manufactured by Emerson (Rosemount division). The 3144 provides high accuracy, stability, and reliability for temperature measurement in critical control and safety applications. The Rosemount 3144P Temperature Transmitter provides high accuracy, stability and reliability for your temperature measurements. It features a dual-compartment housing to ensure reliability and advanced diagnostics to keep your measurement point up and running.
Key Features
- Available with either 4-20 mA/HART or a completely digital FOUNDATION fieldbus protocol
- Can be configured for a variety of sensor inputs: RTD, thermocouple, millivolt, or ohm
- Transmitter-Sensor Matching feature eliminates interchangeability error, which improves accuracy by 75%
- Hot Backup feature can reduce the risk of losing important temperature measurements by 80% when the measurement automatically switches to the backup sensor if the primary sensor fails
- Integral LCD Display (optional) conveniently displays sensor values and transmitter diagnostics information
- NEMA 4X, CSA Enclosure Type 4X, IP66, and IP68
Technical Specifications
- Input sensor types: RTD (Pt 100, Pt 1000), Thermocouple, Millivolt, Ohm
- Capability to accept either single-sensor or dual-sensor inputs. This dual sensor input capability allows the transmitter to accept simultaneous input from two independent sensors, enabling measurement of differential temperatures, averaging temperature or redundant temperature measurement
- Output protocol options: HART 4-20 mA or FOUNDATION Fieldbus
- Standard field mount housing has ½–14 NPT conduit entries
- Input/output isolation tested up to 500 V rms (707 V dc)
- Performance within specifications is achieved less than six seconds after power is applied to the transmitter
- HART version approved for use in Safety Instrumented Systems. Meets NAMUR NE 43 and NE 89 recommendations
Typical Applications
The Rosemount 3144 is designed for critical measurement and control environments, including:
- Safety instrumented systems and emergency shutdown systems
- Reactor and process temperature control in chemical plants
- Refinery and petrochemical process monitoring
- Pharmaceutical and food processing quality control
- HVAC and building automation systems
- Differential and redundant temperature measurement applications
