SENSOR CONNECTIONS

Rosemount Sensors

Transmitter to Sensor Wiring

This section covers the steps required to physically install the transmitter including wiring and calibration.

To connect the transmitter to a non-Rosemount sensor, refer to the appropriate wiring diagram in “Universal Sensor Wiring Diagrams” on page E-1. The calibration procedure listed is not required for use with Rosemount sensors.

Flanged and wafer sensors have two conduit ports as shown in Figure 2-7.Either one may be used for both the coil drive and electrode cables. Use the stainless steel plug that is provided to seal the unused conduit port. Use PTFE tape or thread sealant appropriate for the installation when sealing the conduit.

A single dedicated conduit run for the coil drive and electrode cables is needed between a sensor and a remote transmitter. Bundled cables in a single conduit are likely to create interference and noise problems in your system. Use one set of cables per conduit run. See Figure 2-7for proper conduit installation diagram and Table 2-2for recommended cable. For integral and remote wiring diagrams refer to Figure 2-9.
