DescriptionOMEGA™ extension cables are designed for use in connecting a thermocouple probe to a readout or indicator. Made from extension grade thermocouple wire, J, K and E wire types are rated from 0-105°C (32 to 221°F) for the insulation. The range type T extension wire is rated from -60° to 100°C (-76 to 212°F). Used for a wide variety of applications, these cables are constructed with color-coded extruded PVC or PFA applied to each wire leg. Another color-coded sheath of the same material is then extruded over the two primary legs. A metal overbraid is then applied over the insulated wire: tinned copper over PVC wire, stainless steel over PFA wire. This overbraid adds durability, flexibility and long-term abrasion protection to the wire, in addition to providing electrical shielding for use in noisy environments. Finally, a third layer of PVC or PFA is extruded over the entire assembly to protect the metal overbraid.
