Wire the sensor
Figures in this section provide the guidelines for wiring the sensor to various
transmitters. To determine which wiring guideline to use, locate the model
number of the transmitter to be installed.
WARNING
Electrical shock
Serious injury may result.
Do not connect sensor cable to power lines.
1. If you need to extend the cable (maximum distance from sensor to
transmitter is 250 ft. [76.2 m]), use a high quality eleven conductor
double shielded instrument cable available from Rosemount
Note
If the cable is too long, loop up the excess cable. If you need to
shorten the cable, cut and terminate each conductor neatly and
make sure that the overall (outermost) drain wire is not shorted out
with either of the two inner drain wires (shields).
2. Run signal cable in a dedicated conduit (preferably an earth
grounded metallic conduit) and keep it away from AC power lines.
For your convenience, Emerson has furnished a wire nut kit (in a
plastic bag wrapped around the cable.
Note
For maximum EMI/RFI protection when wiring from the sensor to the
junction box, connect the outer braid of the sensor to the outer
braided shiedl of the extension cable. Terminate the outer braid of
the extension cable at earth ground with an appropriate cable gland
fitting that provides a secure connection to the instrument cable.
The sensor has a mating cable with built-in preamplifier and comes with a
shielded cable. Handle the cable carefully and keep it dry and free of
corrosive chemicals at all times. Take extreme care to prevent it from being
twisted, damaged, or scraped by rough, sharp edges or surfaces. Please refer
to through for wiring the sensor.
