Rosemount 8732
Rosemount recommends using the combination signal and coil drive for N5,
E5 approved sensors for optimum performance.
Remote transmitter installations require equal lengths of signal and coil drive
cables. Integrally mounted transmitters are factory wired and do not require
interconnecting cables.
Lengths from 5 to 1,000 feet (1.5 to 300 meters) may be specified, and will be
shipped with the sensor.
Conduit Cables Run the appropriate size cable through the conduit connections in your
magnetic flowmeter system. Run the power cable from the power source to
the transmitter. Run the coil drive and electrode cables between the sensor
and transmitter.
Prepare the ends of the coil drive and electrode cables as shown in Figure
2-8. Limit the unshielded wire length to 1-inch on both the electrode and coil
drive cables.
NOTE
Excessive lead length or failure to connect cable shields can create electrical
noise resulting in unstable meter readings.
