Dwyer Instruments TR-7-A | Ground Continuity Control with 36" cable | Stud contactor
The temperature sensor Dwyer TR-7-A Safe-T-Ground is made for dangerous environments. Operating temperatures range from -13 to 104°F (-25 to 40°C), and 105-125 VAC power supply is needed for it to function. The housing is constructed from copper-free 356-T6 cast aluminum alloy, providing explosion-proof defense. Its 3/4" NPT conduit connection and DPDT electrical rating of 10 amps, 125 VAC, 60 Hz are its highlights. The unit is 6-5/8" W x 10-3/8" H x 5-5/8" D. Installation lugs measuring 7/16" are included with the unit. With a terminal strip, the wiring is completed. The supplied contactor has a 16-2 type SO coiled cable that retracts to 3' and extends to 16'. It is constructed of molded polyethylene and has contact clips made of berylium copper.
