GETTING ACQUAINTED
WITH THE TRANSMITTER
The Rosemount Model 3144 and 3244MV Smart Temperature
Transmitters are microprocessor-based instruments that accept input
from a wide variety of sensors, and transmit temperature data to a
control system or transmitter interface. The transmitters combine
Rosemount reliability with the flexibility of digital electronics. The
transmitters are ideal for applications that require high performance or
remote communication.
Each transmitter is designed to communicate with a HART
communicator. Communicators are used to interrogate, configure, test,
or format the transmitter, as well as other products in the Rosemount
family of microprocessor-based instruments. Moreover, HART
communicators can communicate with a transmitter from the control
room, from the transmitter site, or from any other wiring termination
point in the loop where there is between 250 and 1100 ohms resistance
between the transmitter power connection and the power supply.
Special dual-sensor features of the Model 3244MV include Hot
Backup
®
, drift alert, differential and average temperature
measurements, and four simultaneous measurement variable outputs
in addition to the analog output signal.
SOFTWARE
COMPATIBILITY
Software for Rosemount SMART FAMILY products is revised
periodically. Replacement transmitters may contain revised software
that is incompatible with the existing software in your HART
communicator.
Software loaded into the Model 275 HART Communicator that contains
device descriptors (DDs) compatible with the Model 3144 and 3244MV
transmitters can be included in the communicator initially, or entered
at any Rosemount Service Center upon request. Rerange and read-only
capabilities can be attained with revision 5.0 or later Model 268
communicator software. The HART Communicator Field Device
Revision Dev v2, DD v1 should be loaded into the Model 257 HART
Communicator in order to utilize all of the features available in the
Model 3144 and 3244MV. See Appendix B: Model 275 HART
Communicator for more information concerning device revisions.
Upgrading the Model 268 software to revision 7.0 will allow limited
functionality such as changing the sensor type and number of wires,
and performing trim functions. The Model 275 HART Communicator is
the necessary interface for complete functionality, and is recommended.
Contact the Rosemount Service Center nearest you to obtain the
appropriate HART communicator software.
