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.
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.
