Product Overview
Type T thermocouple bare wire consists of uninsulated copper (positive) and constantan (negative) conductors designed for direct temperature sensing in non-corrosive environments. This high-accuracy solution is ideal for laboratory testing, cryogenic applications, and custom sensor assemblies where insulation isn't required.
Standard Designations
- Thermocouple Type: T-type (Copper-Constantan)
- IEC Standard: IEC 60584-1
- ANSI Standard: ANSI MC96.1
- Color Coding: Positive (blue), Negative (red) per IEC standards
Key Features
- Direct thermal contact with measured objects via uninsulated design
- High accuracy across -200°C to 350°C range
- Exceptional stability in cryogenic environments
- Low electrical resistance minimizes signal loss
- Compatible with standard T-type connectors
