Product Overview
N-Type thermocouple bare wire consists of two uninsulated conductors: a positive leg made of Nicrosil (nickel-chromium-silicon alloy) and a negative leg made of Nisil (nickel-silicon-magnesium alloy). Designed for high-temperature sensing in oxidizing environments, it offers excellent stability and accuracy across a wide temperature range. Ideal for industrial furnaces, heat treatment, and aerospace applications where direct thermal contact is required.
Standard Designations
- Thermocouple Type: N-Type (Nicrosil-Nisil)
- IEC Standard: IEC 60584-1
- ANSI Standard: ANSI MC96.1
- Color Coding: Positive (NiCrSi) - orange; Negative (NiSi) - red (per IEC)
Key Features
- Uninsulated design for direct heat transfer
- Wide temperature range with high stability
- Superior oxidation resistance at elevated temperatures
- Low drift rate for long-term measurement accuracy
- Compatible with standard N-Type connectors and extension wires
