Description:

The Rosemount Analytical Model 5081 family of transmitters can be used to measure pH, ORP, conductivity (using either contacting or toroidal sensors), resistivity, oxygen, free chlorine, total chlorine, and ozone in a variety of process liquids. The 5081 is compatible with most Rosemount Analytical sensors. With a rugged, weatherproof, corrosion-resistant enclosure (NEMA 4X and IP65) of epoxy-painted aluminum, the 5081 meets NEMA 7B explosion-proof standards making it possible to locate the transmitter close to the sensor even in the harshest environments.

The Rosemount Analytical 5081 transmitter is simple to set-up and operate. A large, easy to read two-line display shows the process measurement and temperature. The 5081 includes the HART or Foundation Fieldbus digital communication protocols which allows users to set-up, configure, read process variables, and troubleshoot problems via PC or HART communicator. Additionally, an optional handheld infrared remote controller can also be used for programming and calibrating the transmitter. The remote controller works from as far away as six feet.

During calibration and programming, messages and prompts appear in the second line.

Temperature resolution: 0.1°C

Competitive Advantage:

VARIOUS MEASUREMENTS including pH, ORP, Contacting or Toroidal Conductivity, Dissolved Oxygen (ppm & ppb), Free Chlorine, Total Chlorine, Ozone.

CHOICE OF COMMUNICATION PROTOCOL with HART® or FOUNDATION® fieldbus.

LARGE, EASY-TO-READ two-line display shows the process measurement and temperature.

ROBUST NEMA 4X ENCLOSURE and epoxy-painted aluminum makes this model weatherproof and corrosion-resistant (NEMA 4X and IP65.)

INTRINSICALLY SAFE DESIGN allows the transmitter to be used in hazardous environments (with appropriate safety barriers.)

NON-VOLATILE MEMORY retains program settings and calibration data during power failures.

HART® (model option -HT) and FOUNDATION® fieldbus (model option -FF) options are available. Digital communications allows access to AMS™ (Asset Management Solutions) which is used to set up and configure the transmitter, read process variables, and troubleshoot problems from a personal computer or host anywhere in the plant.

HANDHELD INFRARED REMOTE CONTROLLER or the HART® Model 275 communicator can also be used for programming and calibrating the transmitter. The remote controller works from as far away as six feet.
