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.
