Rosemount™ 5081 Explosion-Proof Transmitter

Rosemount™ 5081 Two-Wire Transmitters for pH, ORP, Conductivity, Oxygen, Ozone,and Chlorine

Product Description

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.

Features and applications

The 5081 family of transmitters can be used to measure pH, ORP, conductivity (using either contacting or toroidalsensors), resistivity, oxygen (ppm and ppb level), free chlorine, total chlorine, and ozone in a variety of process liquids.The 5081 is compatible with most Rosemount Analytical sensors. See the Specification sections for details.

The transmitter has a rugged, weatherproof, corrosion- resistant enclosure.

The transmitter has a two-line seven-segment display. The main measurement appears in 0.8-inch (20 mm) highnumerals. The secondary measurement, temperature (and pH if free chlorine is being measured), appears in 0.3-inch(7 mm) high digits.

Two digital communication protocols are available: HART® (model option -HT) and FOUNDATION™ Fieldbus (model options-FF or -FI). Digital communications allows access to AMS (Asset Management Solutions). Use AMS to set up andconfigure the transmitter, read process variables, and troubleshoot problems from a personal computer or hostanywhere in the plant.

A handheld infrared remote controller or the HART and FOUNDATION™ Fieldbus 375 communicator can also be used forprogramming and calibrating the transmitter. The remote controller works from as far away as six feet.

Specifications

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).

Certifications/Approvals 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.

Weight 10 lb/11 lb (4.5/5.0 kg)

Features

• Robust explosion-proof design constructed with heavy duty cast aluminum

• Faster installation using Quick Start programming

• Intrinsically safe, non-incendive, and explosion-proof hazardous area location approvals

• Visibility of process parameters by utilizing HART® or Profibus DP digital communications

• Effortlessly connect with PLCs and DCSs by choosing the HART® or FOUNDATION™ Fieldbus communication options
