DescriptionMineral insulated metal sheathed RTD Cable, RTD MIC, has a stainless steel or Inconel outer metal sheath with copper or Nickel signal wire conductors. The conductor lead wires are insulated from each other and the outer sheath by compacted magnesium oxide MgO. Metric and standard US inch diameters are manufactured in a range of OD sizes with 2, 3, or 4 conductors. The 4 wire design is produced in wide or standard pattern layout in various diameters. Coil lengths of 50 to 1000 ft are typical. Metal sheath RTD cable with nickel 201 conductors is also used as sensor hook up wire in high temperature locations.
