When discussing a 3-core mineral insulated cable (MIC) of the K
type for thermocouples, specifically in the 4.0-8.0 mm range, there
are several key aspects to consider:
Overview of K Type Thermocouples:
K Type Thermocouples: These are made from Chromel (Nickel-Chromium
alloy) and Alumel (Nickel-Aluminum alloy) and are one of the most
common types due to their wide temperature range (-200°C to 1260°C)
and good stability.
Thermocouple Functionality: Thermocouples work by measuring the
voltage generated at the junction of two different metals, which
correlates to temperature.
Features of 3-Core Mineral Insulated Cable:
Construction:
Core: The cable contains three conductors, typically two for the
thermocouple (Chromel and Alumel) and a third for a reference or
compensation wire.
Insulation: The conductors are insulated with mineral insulating
material (often magnesium oxide), which allows for high thermal
conductivity and excellent dielectric properties.
Sheathing: Typically, the cable is sheathed in a metal sheath (such
as stainless steel), providing mechanical protection and resistance
to corrosion and high temperatures.
Diameter:
4.0-8.0 mm: This indicates the outer diameter of the cable. The
choice of diameter affects flexibility, installation ease, and the
thermal response time of the thermocouple.
Temperature Range:
Mineral insulated cables can withstand high temperatures, making
them suitable for industrial applications.
Applications:
Used in harsh environments, such as furnaces, reactors, and other
industrial processes where precise temperature measurement is
crucial.
Advantages:
Durability: Resistant to moisture, corrosion, and extreme
temperatures.
Response Time: Fast response to temperature changes due to the
compact nature of the construction.
Accuracy: High accuracy and stability over a wide temperature
range.
Considerations for Use:
Ensure compatibility with the measurement system and calibration.
Consider the environment where the thermocouple will be used,
including exposure to chemicals or mechanical stress.
Proper handling during installation is necessary to avoid damaging
the cable or its insulation.
We add heat shrink tubing and plastic film to ensure high insulated
resistance. Each coil cable includes marking notes, pass card and
test report.
We have high-quality professional products with advanced production
lines and equipment. All products comply with international quality
standards and are appreciated in global markets. We continuously
improve our production systems and product quality to meet
increasing market demands.
