Type T Thermocouple Bare Wire Copper Constantan -200°C to 350°C

Product Description​

Type T Thermocouple Bare Wire​

Product Overview

Type T thermocouple bare wire is composed of two uninsulated conductors: a copper positive leg and a constantan (copper - nickel alloy) negative leg. It is specifically designed for direct temperature sensing in non - corrosive and clean environments, providing high accuracy in low to medium temperature ranges. This product is ideal for laboratory testing, cryogenic applications, and custom sensor assemblies where insulation is not necessary.

Standard Designations

Thermocouple Type: T - type (Copper - Constantan)

IEC Standard: IEC 60584 - 1

ANSI Standard: ANSI MC96.1

Color Coding: Positive leg (copper) - blue; Negative leg (constantan) - red (in accordance with IEC standards)

Key Features

Uninsulated design enables direct thermal contact with the measured object

High accuracy in the temperature range of - 200°C to 350°C

Excellent stability in cryogenic environments

Low electrical resistance to minimize signal loss

Compatible with standard T - type connectors
