The document describes the features of the Welded Tip Thermocouples Glass fibre Insulated Leads, including fast response, exposed junction, and suitability for test and development applications.
The welded tip thermocouples feature a fast‑response exposed junction and are available in IEC‑standard types J and K. Each lead is 3 m long, insulated with glass fibre that is silicone‑varnished, and uses 1/0.315 mm conductors.
These thermocouples are supplied in packs of five and are intended for test and development applications. Part numbers and distributor codes are provided (e.g., Farnell Labfacility stock codes 163‑3477 Z3 for J‑3M and 163‑3479 Z3 for K‑3M).
