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
Technical Specifications
Temperature Range -200°C to 350°C (continuous); 400°C (short-term)
EMF Output at 100°C 4.277 mV (reference junction at 0°C)
Accuracy Class 1: ±0.5°C or ±0.4% of reading
Available Wire Diameters 0.12mm, 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1.0mm
