Special Mounting
Considerations

Special mounting hardware is available for mounting a
Model 244EH head mount transmitter to a DIN rail, or assembling
a new Model 244EH to an existing threaded sensor connection head
(former option code L1).

Mounting a Model 244EH to a DIN Rail

To attach a head mount transmitter to a DIN rail, assemble the
appropriate rail mounting kit (part number 00644-5301-0010) to the
transmitter as shown in Figure 2-3, then follow the procedure under
“Rail Mount Transmitter with Integral Mount Sensor” on page 2-7.

Retrofitting a Model 244EH for Use in an Existing Threaded Sensor
Connection Head

To mount a Model 244EH in an existing threaded sensor connection
head (former option code L1), order the Model 244EH retrofit kit (part
number 00644-5321-0010). The retrofit kit includes a new mounting
bracket and all associated hardware necessary to facilitate the
installation of the Model 244EH in the existing head.
