TOOLS NEEDED FOR INSTALLATION

The tools needed for installation are as follows:

MOUNTING

The Models 644H and 644R transmitters will operate within specifications for

ambient temperatures between –40 and 185 °F

(–40 and 85 °C).

Special Mounting Considerations

Special mounting hardware is available for mounting a Model 644H head mount

transmitter to a DIN rail, or assembling a new Model 644H to an existing threaded

sensor connection head (former option code L1).

Mounting a Model 644H 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 2-2, then follow the procedure under “Rail Mount Transmitter with

Integral Mount Sensor” on page 2-7.
