Conduit Cables

Figure 2-9. Cable Preparation Detail

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.

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

2-9. 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.
