IMARI WIC-H Thermocouple Extension Wire

(タイプJ / Iron-Constantan)

品目番号. 1280001068.

One-Line Positioning

A high-temperature-resistant, glass-fiber-insulated Type J thermocouple extension wire that carries thermocouple temperature signals over long distances with low error to instruments/PLCs — suited to high-temperature industrial environments.

コア仕様

Series comparison: WIC-G (PVC vinyl insulation, -20~+90 ℃, suited to humid locations); WIC-H (fiberglass jacket, higher temperature rating, suited to high-temperature applications); WIC-H (SUS) (stainless-steel shield, EMI protection, abrasionand scratch-resistant, suited to heavy-duty/frequent-movement use).

IMARI WIC-H Thermocouple Extension Wire (タイプJ / Iron-Constantan)

技術的特徴

High-temperature resistance: The fiberglass jacket allows continuous use from 0 に 150 ℃, well beyond standard PVC wire (-20~+90 ℃), making it suitable for high-temperature furnaces, boilers, 射出成形, and similar applications.

Signal accuracy: The iron-constantan material matches the thermoelectric EMF characteristics of Type J thermocouples, acting as a compensating lead to offset errors from cold-junction temperature differences and maintaining measurement-loop accuracy.

Abrasion resistance & EMI immunity (オプション): Where interference protection or frequent bending and abrasion are concerns, the SUS stainless-steel-shielded version can be selected.

Selectable conductors: Two strand configurations, 4-strand or 7-strand, for selection based on routing strength and signal-stability needs.

アプリケーションシナリオ

High-temperature industrial measurement loops, heat-treatment furnaces, boiler and flue-gas monitoring, 射出成形 / die-casting equipment, laboratory high-temperature apparatus, and any automated control system that requires long-distance transmission of Type J thermocouple signals.

セレクションガイド

高温環境 (within 150 ℃) → choose WIC-H (このモデル).

Humid environment, temperature below 90 ℃ → choose WIC-G.

Strong interference / frequent movement → choose the WIC-H (SUS) stainless-steel-shielded version.

Conductor density: for low-resistance, long-distance transmission, prefer the 7-strand version.

IMARI WIC-H Thermocouple Extension Wire (タイプJ / Iron-Constantan) — Main Uses

The primary purpose of the IMARI WIC-H is to transmit the thermocouple’s temperature signal over long distances with low error to indicating instruments, PLC, or other control systems. The core concept: the thermocouple element measures temperature, while the extension wire carries that signal from the sensor to the instrument end and compensates for cold-junction temperature error.

代表的な用途

Industrial furnaces & heat treatment: signal transmission for high-temperature measurement in melting furnaces, annealing furnaces, hardening/tempering furnaces, 等;

ボイラー & flue-gas / piping monitoring: boiler combustion temperature and flue-gas duct temperature monitoring;

Plastics processing: temperature-control loops for the barrel and mold of injection molding and extrusion machines;

Metals & die casting: measurement loops for die-casting molds and molten-metal temperature;

研究室 & R&D: temperature acquisition for high-temperature ovens, tube furnaces, and other experimental equipment;

力 & エネルギー: online temperature monitoring of transformers, motor windings, and similar equipment;

Automated control systems: collecting Type J thermocouple signals from field locations into PLC / DCS / 温度コントローラー.

In one sentence: anywhere you measure temperature with a Type J thermocouple and the distance between the sensor and the instrument is significant, use a compensating wire such as the WIC-H for the connection. The fiberglass jacket (このモデル) is chosen because it withstands 150 ℃, making it suitable for routing near heat sources.
