Product Description
T-Type Thermocouple Wire with PVC Insulation
Product Overview
T-Type thermocouple wire with PVC insulation consists of a copper
positive leg and a constantan (copper-nickel alloy) negative leg,
each individually insulated with PVC. The PVC jacket provides
electrical insulation and protection against moisture, making it
suitable for low to medium temperature sensing in non-corrosive
environments. Widely used in food processing, HVAC systems, and
environmental monitoring where insulated wiring is required.
Standard Designations
- Thermocouple Type: T-Type (Copper-Constantan)
- IEC Standard: IEC 60584-1
- Insulation Standard: PVC meets UL 94 V-0 flammability rating
- Color Coding: Positive (copper) - blue insulation; Negative (constantan) - red insulation (per IEC)
Key Features
- PVC insulation for electrical isolation and moisture resistance
- Operating temperature range compatible with PVC’s thermal limits
- Flexible design for easy installation in tight spaces
- Color-coded conductors for quick identification
- Suitable for dry and moderately humid environments
