N Type Thermocouple Inconel600 Shealth

This combination of an N-type thermocouple with an Inconel 600 sheath makes it ideal for applications requiring precise temperature measurement in high-temperature, corrosive, or demanding industrial environments, such as in furnaces, chemical processing, or power generation systems.

Products Description

A Sheath-type N-type Thermocouple with an Inconel 600 sheath is a specialized temperature-sensing device designed for reliable operation in demanding environments.

Here's a detailed overview:

Core Component: N-type Thermocouple

- Working Principle: Operates on the Seebeck effect, where two dissimilar metal conductors (typically Nicrosil/Nisil alloys) form a closed loop. A measurable electromotive force (EMF) is generated when there is a temperature difference between the measuring junction (hot end) and the reference junction (cold end), allowing temperature calculation via the EMF value.
- Key Advantages:
- Excellent oxidation resistance up to 1300°C, making it suitable for high-temperature applications.
- Superior long-term stability and repeatability under thermal cycling, ensuring consistent measurements over time.
- Good resistance to nuclear radiation and low-temperature environments.
- More linear thermoelectric performance than K-type thermocouples in the 400–1300°C range, though nonlinearity increases in the -200–400°C range.
- Note: The alloy materials are relatively hard, which may complicate machining processes.

Inconel 600 Sheath

- Material Characteristics: A nickel-chromium alloy (approx. 76% Ni, 16% Cr, 8% Fe) renowned for its high-temperature strength and corrosion resistance. It maintains structural integrity at temperatures up to 1093°C and resists corrosion from most common acids, alkalis, and ultrapure water.
- Function: Acts as a protective barrier for the internal thermoelements, shielding them from mechanical damage, chemical erosion, and harsh environmental conditions (e.g., high humidity, dust, or aggressive gases). This protection ensures the thermocouple's accuracy and extends its service life, even in industrial or high-temperature settings.

This combination of an N-type thermocouple with an Inconel 600 sheath makes it ideal for applications requiring precise temperature measurement in high-temperature, corrosive, or demanding industrial environments, such as in furnaces, chemical processing, or power generation systems.
