| More Information: |
The 5081-P-FF Device Revision 3 is the latest version of the 5081 series
of Fieldbus transmitters and is the first of the series to be tested to
ITK 6 requirements.
The 5081-P-FF measures pH (0 to 14 pH) and ORP (-1,500 to 1,500 mV), and
provides full comprehensive sensor, transmitter, and calibration
diagnostics, which are 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 5081-P-FF is provided with a
Link Active Scheduler.
4 AI Function Blocks are provided for PV, temperature, reference
electrode impedance, and glass electrode impedance. A PID Analog Control
Function Block is also provided to allow the transmitter to participate
in applications requiring control in the field.
The 5081-P-FF display is a two-line LCD; first line shows process
variable (pH or ORP) 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.)
