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
