Dwyer Instruments' Series RRT3 Remote Reading Thermometer combines a dual-scale dial thermometer and an SPDT relay
Dwyer Instruments' Series RRT3 Remote Reading Thermometer With Switch combines a 3 ¼-inch dual-scale dial thermometer and an 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 is engineered to prevent the set point pointer from sticking to the process indicating pointer. A 10.5-foot (3.2-meter) stainless steel flex hose capillary is made to prevents kinking and leaking of the measuring fluid when bending the capillary. 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.
