Rosemount

5081 Explosion-Proof Transmitter

Single-channel loop-powered (4-20 mA HART) liquid analysis transmitter in an explosion-proof housing. Accepts pH/ORP, contacting / toroidal conductivity, and amperometric (DO / chlorine / ozone) sensors. Rugged weatherproof corrosion-resistant enclosure for hazardous-area installations (Class I Div 1, Zone 1) — the Rosemount Analytical choice when other transmitters need separate explosion-proof enclosures and conduit fittings. Loop-powered means no separate power supply or 4-wire conduit run.
