Mounting
The Rosemount 644H installs in a connection head or universal
head mounted directly on a sensor assembly, apart from a sensor
assembly using a universal head, or to a DIN rail using an optional
mounting clip.
Special mounting considerations
See
Figure A-5 on page 89
for the special hardware that is available
to:
Mount a Rosemount 644H to a DIN rail. (see
page
88)
Retrofit a new Rosemount 644H to replace an existing
Rosemount 644H Transmitter in an existing threaded sensor
connection head.(see
