5.7 Wire the remote core processor to the sensor
using shielded or armored cable
For ATEX installations, shielded or armored cable must be installed with cable glands, at
both the sensor and remote core processor ends. Cable glands that meet ATEX
requirements can be purchased from Micro Motion. Cable glands from other vendors can
be used.
CAUTION!
Keep cable away from devices such as transformers, motors, and power lines, which produce
large magnetic fields. Improper installation of cable, cable gland, or conduit could cause
inaccurate measurements or flow meter failure.
CAUTION!
Install cable glands in the 9-wire conduit opening in the transmitter housing and the sensor
junction box. Ensure that the cable drain wires and shields do not make contact with the
junction box or the transmitter housing. Improper installation of cable or cable glands could
cause inaccurate measurements or flow meter failure.
CAUTION!
Improperly sealed housings can expose electronics to moisture, which can cause measurement
error or flowmeter failure. Install drip legs in conduit and cable, if necessary. Inspect and
grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.
1. Identify the components of the cable gland and cable.
