Sensor Compatibility and Interchangeability
The Rosemount 8721 Sensors are interchangeable with Rosemount 8732
and 8712E transmitters. System accuracy is maintained regardless of line
size or optional features.
Each sensor nameplate has a sixteen-digit calibration number that can be
entered into the transmitter through the Local Operator Interface (LOI) or the
Field Communicator. In a digital fieldbus environment, the 8732E can be
configured using compatible digital fieldbus configuration tool. No further
calibration is necessary.
Conductivity Limits
Process liquid must have a conductivity of 5 microsiemens/cm (5
micromhos/cm) or greater. Excludes the effect of interconnecting cable length
in remote mount transmitter installations.
Sensor Coil Resistance
5
to 10
(line size dependent)
Flow Rate Range
Capable of processing signals from fluids that are traveling between 0.04 and
39 ft./s (0.01 to 12 m/s) for both forward and reverse flow in all sensor sizes.
Full scale continuously adjustable between –39 and 39 ft./s (–12 to 12 m/s).
