A “2.5mm KN Thermocouple Wire” likely refers to a thermocouple wire with a diameter of 2.5 millimeters and composed of a thermocouple type known as “KN.”
The term “KN” indicates the type of thermocouple. However, it’s unusual to see “KN” as a standard thermocouple type designation. Thermocouples are typically identified by letter combinations such as “K,” “N,” “T,” etc., each representing a specific combination of metals used in the thermocouple pair.
For example:
- Type K thermocouples use chromel (nickel-chromium alloy) and alumel (nickel-aluminum alloy).
- Type N thermocouples use Nicrosil (nickel-chromium-silicon alloy) and Nisil (nickel-silicon alloy).
It’s possible that “KN” could refer to a custom or proprietary thermocouple type, but without further context or information, it’s challenging to determine precisely what it represents.
Regarding the wire diameter, “2.5mm” indicates the thickness of the thermocouple wire, which is 2.5 millimeters. This measurement determines the physical size of the wire and may impact its mechanical properties, flexibility, and resistance to environmental factors.
