Rosemount™ 5081 Explosion-Proof Transmitter
rosemount 5081 explosion-proof transmitter
The Rosemount 5081 Explosion-Proof Transmitter is a single channel loop powered device that can accept input from a variety of liquid analysis sensors including: pH/ORP sensors, conductivity sensors (contacting and toroidal) and amperometric sensors (dissolved oxygen, chlorine and ozone).
The transmitter features a rugged, weatherproof, corrosion-resistant enclosure to withstand harsh environments.
Rosemount™ 5081 Explosion-Proof Transmitter


Measurement Range
Varies by sensor type. See Product Data Sheet for details.
Operating Temperature
-4 - 149 °F (-20 - 65 °C)
Power Supply
Minimum power supply voltage is 12 Vdc. Maximum power supply voltage is 42.4 Vdc (30 Vdc for intrinsically safe operation). Power supply voltage should cover the voltage drop on the cable plus the external load resistor required for HART® communications (250 Ω minimum).
For details, see specifications for the measurement of interest.
Enclosure Rating
Cast aluminum containing less than 6% magnesium, with epoxy polyester coating. NEMA 4X (IP65). Neoprene O-ring cover seals.
10 lb/11 lb (4.5/5.0 kg)
