Dwyer Instruments RRT3 Series Installation And Operating Instructions

The Series RRT3 Remote Reading Thermometer with Switch combines an
easy to read 3-1/4˝ dual scale dial thermometer and a SPDT relay. Color
coordinated pointers display the current process temperature and set point. In
order to change the set point, a front adjustment knob controls the red set point
pointer. The design of the internal mechanical switch movement prevents the set
point pointer from sticking to the process indicating pointer. A 10.5 ft (3.2 m)
stainless steel flex hose capillary prevents kinking and leaking of the measuring
fluid when bending the capillary. For quick installation, electrical connections can
be made to male quick connects or to the finger-safe screw terminals.
Thermometer includes a u-clamp mounting bracket for panel mounting.
