The two wires that make up the thermocouple pair are made from a range of different alloys and metals and have been standardised by both international and national bodies.
Why do we use thermoocuple wires?
Thermocouple wires are used in temperature measurement applications due to their unique properties and advantages:
Temperature Measurement: Thermocouples are sensors used to measure temperature. They work based on the principle that when two dissimilar metals are joined together, a voltage is generated that is proportional to the temperature difference between the hot junction (where the two metals meet) and the cold junction (where the wires are connected to the measuring instrument).
Wide Temperature Range: Thermocouples can measure a wide range of temperatures, from cryogenic temperatures to high temperatures exceeding 2000°C, making them suitable for various industrial and scientific applications.
Durability: Thermocouples are robust and can withstand harsh environments, vibrations, and high pressures, making them ideal for use in industrial settings where other temperature sensors might fail.
Fast Response Time: Thermocouples have a quick response time, providing real-time temperature readings, which is crucial in processes where temperature changes rapidly.
Cost-Effective: Thermocouples are relatively inexpensive compared to other temperature sensors, making them a cost-effective choice for many temperature measurement applications.
Flexibility: Thermocouple wires are flexible and can be easily shaped to fit different applications, making them versatile for various industries like manufacturing, food processing, automotive, aerospace, and more.
K-type thermocouple wire is a common type of thermocouple composed of two different metal alloys: nickel/silicon alloy (usually referred to as KN or KNX) and nickel/chromium alloy (usually referred to as KP or KPX).
These two alloys have different thermoelectric properties at different temperatures, which can generate a thermoelectric potential difference for temperature measurement. The working temperature range of K-type thermocouple wires is usually between 0 ° C and 1200 ° C, and it is one of the commonly used temperature sensors in many industrial and laboratory applications.
They have good linear characteristics and relatively high accuracy, and their stability at high temperatures is relatively good, so they are widely used in some high-temperature environments.
The connectors of K-type thermocouple wires often use standard K-type plugs, allowing them to be connected to various temperature measuring devices, control systems, recorders, etc., facilitating temperature measurement and data acquisition. Due to the reliability and applicability of K-type thermocouple wires, they are widely used in various industries such as metallurgy, petrochemicals, energy production, and food processing
What differentiates one thermocouple from another is the metals in its two wires: the positive leg and the negative leg. Because each thermocouple type has a different pairing, they differ in temperature limits, process conditions (inert, oxidizing, reducing atmospheres, heavy vibration), and so on.
