Special Mounting Considerations

HART Communicator (Model 644 only)

To guarantee proper transmitter functionality and communication, your Model

275 HART Communicator should contain device revision Dev v5 DD v2 or higher.

To check software device revision,

1. Turn on the communicator.

2. Select 1 Off-line, 1 New Configuration, Rosemount, 644 Temp

If you do not have this device revision, contact your local Rosemount

representative for information on receiving an upgrade.

Use with an Existing DIN Plate Style Sensor

1. Secure the bottom of the mounting screw

sleeve with pliers. Remove the mounting

screws and springs.

2. Once the springs are removed, use the

new transmitter mounting screws to

assembly the transmitter to the DIN plate

and connection head. (Optional snap rings

(part number 00644-4432-0001) are

available to ease installation o an existing

DIN plate style sensor.)

Use with an Existing Threaded Sensor Connection Head

To mount the new Models 644H or 244EH to an

existing threaded sensor connection head (former

option code L1), order the Models 644H and 244EH

retrofit kit (part number 00644-5321-0010). The fit

includes a new mounting bracket and all associated

hardware necessary to facilitate the installation of the

Models 644H and 244EH into the existing head.
