NEW-FLOW ETS3000X explosion-proof temperature switch adopts gas/liquid filled thermal expansion sensing principle, matched with remote stainless steel capillary for long-distance temperature detection.
Die-cast aluminum explosion-proof enclosure meets international hazardous area standards, NEMA4X & IP65 waterproof dustproof. Built-in pure silver SPDT microswitch provides stable on-off signal for temperature alarm, pump/valve interlock, furnace overheat protection. Two contact options (1 contact / 2 contacts) support dual-point temperature control.
Liquid-filled: -70℃ ~ +400℃, max capillary 20m
Gas-filled: -200℃ ~ +650℃, max capillary 30m
