Micro Motion 9-wire cable types and usage
Cable types
Micro Motion supplies three types of 9-wire cable: jacketed, shielded, and armored. Note the following differences
between the cable types:
• Armored cable provides mechanical protection for the cable wires.
• Jacketed cable has a smaller bend radius than shielded or armored cable.
• If ATEX compliance is required, the different cable types have different installation requirements.
Cable jacket types
All cable types can be ordered with a PVC jacket or Teon
®
FEP jacket. Teon FEP is required for the following installation
types:
• All installations that include a T-series sensor.
• All installations with a cable length of 250 ft (75 m) or greater, a nominal ow less than 20 percent, and ambient
temperature changes greater than +68 °F (+20 °C).
Table 4-4 shows the temperature ranges of the cable jacket materials.

Cable bend radii
The following tables show the cable bend radii of the different cables and the jacket materials:
• Table 4-5 shows the bend radii of jacketed cable.
• Table 4-6 shows the bend radii of shielded cable.
• Table 4-7 shows the bend radii of armored cable.
