Wire Thermocouples & Bulk Wire

Insulation is applied to each wire individually, and then again combined as a duplex pair. The insulation may be extruded, taped, wrapped, served, braided, or applied using other means depending on insulation material and desired characteristics. The insulation isolates each wire from the other electrically and may also serve to identify the calibration type and identify the polarity of each wire. Some types of high temperature insulation cannot accept color coding, and tracer materials are added to the wire braid for identification. Selection of insulation type is dependent on the determining factors of: the end application, the maximum usage temperature, and the atmosphere. Other factors when choosing insulation material are flexibility, abrasion, and electromagnetic interference. In addition to the outer insulation, other layers may be added like foils or stainless-steel exterior braiding to provide electrical shielding or abrasion resistance. Cleveland Electric Laboratories maintains a large inventory of many stock wire configurations. Custom combinations are available upon request.

Thermocouple and Extension wire assemblies are available in long, continuous lengths and are custom built to specification. Cold end termination options include stripped, bare ends, industry-standard plugs/jacks, or custom options.

Insulated Thermocouple Wire (ITW) is an effective tool to measure the accuracy and stability of Industrial Furnaces—thus the common terminology of Survey or Profile Thermocouples. Material is available in bulk spools or as made-to-order thermocouples or Thermocouple Kits, all in accordance with industry specifications.

Manufactured with either Insulated Thermocouple Wire (ITW) or Insulated Extension Wire (IEW), CEL can supply application-specific assemblies or harnesses for compatibility to your existing process.

Insulated Thermocouple Wire (ITW) is selected based on calibration, diameter, and insulation material.  Our ITW is typically ordered in bulk spools and may be certified in our ISO/IEC 17025 accredited laboratory.

Insulated Extension Wire
Insulated Extension Wire (IEW) is used as a means to transmit a thermocouple signal from the sensor in process to the recording instrumentation without loss or degradation of the thermocouple signal.  IEW must be compatible with its corresponding thermocouple.

Provide tighter accuracies than base metal assemblies and are manufactured with superior materials capable of withstanding process temperatures up to 3100°F.

Supplied in Types B, R or S, our Noble Thermocouple Wire is suitable for high-temperature and high-accuracy applications. Standard in-stock wire diameters range from .010” to .032”, all available with ISO/IEC 17025 accredited calibration upon request.

Rugged, durable industrial thermocouple assemblies designed for use in the most severe process environments & temperatures up to 2200°F.

From 2 to 36 pair of wire in a common cable, our Multi-Pair Extension Wire is utilized when a single run of instrumentation wiring is desired. This configuration greatly simplifies installation when many wires are routed to a single point. It also occupies less space.

Also known as MgO or MIMS Cable, this material is supplied with a metallic outer sheath, typically Inconel or Stainless Steel. High-temperature magnesium-oxide insulation encapsulates the thermo conductors, isolating the conductors from each other as well as the outer sheath. This versatile product is manufactured for flexibility and is able to be wrapped around a mandrel twice the diameter of the cable.
