Rosemount 3144P temperature transmitter

High-performance temperature transmitter is an excellent solution for single-point measurement applications

The accuracy, stability and reliability of Rosemount 3144P temperature transmitter (equipped with HART or FOUNDATION fieldbus protocol) are at the leading level in the industry. 3144P adopts dual-chamber on-site electromechanical installation configuration, which can prevent water from entering the transmitter and protect the transmitter from electromagnetic surges. The 5-year stability and the optional integrated lightning protection terminal make the 3144P a reliable temperature measuring instrument. Rosemount 3144P is equipped with the function of receiving single sensor and dual sensor input, so it can receive input from two independent sensors at the same time. The dual sensor configuration can be used to balance temperature, measure temperature difference, perform redundant temperature measurement, and use important functions such as hot backup and sensor drift alarm. Users can use advanced diagnostic functions to detect sensor drift, possible thermocouple sensor aging or line interruption, and better monitor programs and equipment.

Single sensor and dual sensor input function in one transmitter
In process measurement, stable and enhanced EMI elimination and filtering results can be obtained
Comply with IEC61508 safety certification third-party verification standard for instrumented safety system (SIS)
Industry-leading 5-year stability, reducing maintenance costs
Hot Backup® and sensor deviation alarm can gradually improve measurement stability
Transmitter-sensor matching technology reduces sensor interchangeability errors and increases accuracy by 75%
Dual-chamber enclosure maximizes reliability in harsh environments
Integrated LCD meter head with large, easy-to-read display
The thermocouple aging diagnosis function allows users to monitor the resistance of the thermocouple circuit to detect sensor failures and perform preventive maintenance in advance to avoid downtime
The minimum and maximum temperature tracking function allows users to monitor the temperature of sensor 1, sensor 2 and the difference between the two.
