Rosemount 5081FG Two-Wire In-Situ Oxygen Analyzer

RosemountTM 5081FG Two-Wire In-Situ Oxygen Analyzer (550 °C to 1600 °C)

Rosemount 5081 transmitter is a two-wire transmitter providing an isolated output, 4-20 mA, that is proportional to the measured oxygen concentration. A customer-supplied 24 VDC power source is required to simultaneously provide power to the electronics and a 4-20 mA signal loop. The transmitter accepts millivolt signals generated by the probe and produces the outputs to be used by other remotely connected devices. The output is an isolated 4-20 mA linearized current.

System Features of RosemountTM 5081FG

1. The cell output voltage and sensitivity increase as the oxygen concentration decreases.

2. High process temperatures eliminate the need for external cell heating and increase cellaccuracy.

3. HART communication is standard. To use the HART capability, you must have either:

(a) Field Communicator

(b) Asset Management Solutions (AMS) software for thePC

4. Easy probe replacement due to the light-weight, compact probedesign.

5. Remote location of the Rosemount 5081 transmitter removes the electronics from high temperature or corrosiveenvironments.

6. Power is supplied to the electronics through the 4-20 mAline for intrinsic safety (IS) purposes.

7. Infrared remote control (IRC) allows interfacing without exposing the electronics.

Models of RosemountTM 5081FG

Rosemount™ 5081FG is mainly the 5081FG model, but it can be configured in different ways. For example, there are different combinations in terms of probe length and material:

5081FG-1101H0001111: With a probe length of 508 mm (20 inches), 660 mm (26 inches) or 965 mm (38 inches). The process temperature ranges from 550°C to 1400°C, and the ambient temperature is from -40°C to 149°C. The internal probe is made of zirconia, the tube is made of alumina (with a limit of 1600°C (2912°F)) or Inconel (with a limit of 1000°C (1832°F)), and the probe junction box is made of cast aluminum.

5081FG-1135H1011011:Rosemount Analytical 5081FG Oxygen Analyzer，5081FG-1-1-3-5-H1-01-1-0-11, is a high - temperature oxygen analyzer. It uses zirconia sensor technology, has intrinsic safety features, specific measurement ranges and response times. It transmits data via the 4 - 20mA HART communication protocol and has a series of specific parameter combinations in terms of probe configuration, communication, and functionality. It is suitable for accurately measuring the oxygen content in high - temperature combustion processes.

5081FG with other configurations: It is also available in different probe lengths within the range of 20 in (0.51 m) to 38 in (0.97 m). Besides, the materials of the probe and other components can be selected according to specific needs, and the communication protocol is 4-20mA HART.

5081FG-20 inch probe model: Probe length is 508 mm (20 inches).

5081FG-26 in. probe model: probe length is 660 mm (26 in.).

5081FG-38 in. probe model: probe length is 965 mm (38 in.).

5081FG-HART model: 4-20mA HART communication protocol can realize the communication with the upper computer or control system, transfer the measurement data, equipment status and other information, and also can carry on the remote parameter setting and diagnosis.
