The TX66 “smart” transmitters offer
isolation, linearization, automatic
temperature compensation, automatic
self-calibration, and easy-to-use
menus. These compact units accept
a large number of inputs. The
optional 1-line display will fit within

the same footprint as the

transmitter. The 2-line,

plug-in display is

slightly larger, with

2 pushbuttons

and LCD glass.

Both displays
are field

mountable.

At least 1 display

is required to
set up and

scale the

transmitter.
