More Information:
The 5081-A-FF Device Revision 3 is the latest version of the 5081 series of Fieldbus amperometric transmitters, tested to ITK 6 requirements.    The 5081A measures dissolved oxygen in the range of 0 to 20 ppm or 0 to 270 % saturations with a resolution of 0.01 ppm, or 0.1 ppb when used with the 400TRDO trace oxygen sensor.  The 5081A can also measure total chlorine or free chlorine in the range of 0 to 20 ppm with a resolution of 0.001 ppm.  A pH sensor can be used with 5081A, in addition to the free chlorine sensor, to provide pH corrected free chlorine measurements.  Finally, the 5081A can be configured to measure ozone in the range of 0 to 10 ppm with a resolution of 0.001 ppm.   A comprehensive set of sensor, transmitter, and calibration diagnostics is provided, available to the bus via Field Diagnostics.  The Common Software Download Specification allows software upgrades to be downloaded to the transmitter, while it is in service.  As has always been the case with our transmitters, the 5081A is provided with a Link Active Scheduler.   3 AI Function Blocks are provided for PV, temperature, and amperometric sensor current.  In the case of the free chlorine measurement using a pH sensor input, a fourth AI Block is provided to publish the pH measurement.  A PID Analog Control Function Block is also provided to allow the transmitter to participate in applications requiring control in the field.   The 5081A display is a two-line LCD; first line shows process variable (oxygen, chlorine or ozone concentration) with the second line showing process temperature.  Fault and warning mes­sages, when triggered alternate with temperature and output readings. During calibration and programming, messages and prompts appear in the second line.  The display board can be rotated 90 degrees clockwise or counterclockwise.  The display is accessed using an infrared remote controller, allowing the transmitter to remain sealed during calibration and configuration.   The housing is cast aluminum with epoxy coating. NEMA 4X (IP65) and NEMA 7B, with Neoprene O-ring cover seals. Dimensions: 160.5 mm x 175.3 mm x 161.3 mm (6.3 in. x 6.9 in. x 6.4 in.)
