Thermocouples – Naba-Pak^®

• A wide range of sheath materials and thermocouple types cover a temperature range from -200°C to 1300°C+ (-328°F to 2372°F+)
• A wide range of styles and sizes to match your application.
• Weld-able and braze-able, they can be permanently mounted in process fittings and fixtures.
• Available in long lengths, Naba-Pak® thermocouple length can range from a fraction of an inch to a thousand feet or more.
• This type of construction (mineral insulated – compacted high purity MgO), when properly implemented, protects the thermocouple elements for long life and high accuracy under harsh process conditions.
• Inherently pressure resistant. The compacted mineral insulation forms an effective pressure barrier.
• Naba Pak® thermocouples are bendable and resilient. This is useful in many applications, as it is often desirable to extend the thermocouple to separate the connection end from high temperatures and harsh process environments.
• Fast response and tip sensitive for localized temperature measurement that doesn’t lag behind process conditions.
• Other special coatings and services include: Teflon® coating, Oxygen cleaning, etc.

The grounded junction is the most common type; it has a response time that falls between the exposed and isolated types and offers good thermoelement protection.

Isolated junctions have the slowest response time and are often employed when electrical conditions (such as ground loops) interfere with the thermocouple’s proper operation.

Exposed and sealed thermocouples have the fastest response time for a given diameter Naba-Pak®. On the downside, this type offers limited protection to the thermoelements; a reduced tip offers better service life while maintaining a fast response time.
