● Cement

● Paper & Pulp

K-Type Thermocouples

The most commonly used type in numerous industries and sectors. Type-K units are made from a combination of nickel-based wires (typically chromel/alumel), which results in an especially cost-effective thermocouple that tends to be accurate and reliable across a wide range of operating temperatures.

K-type thermocouples are generally used within ranges of -200 to +1260 celsius and are considered temperature accurate to a standard deviation of ±0.75%. This thermocouples have a wide range of potential applications due to being nickel-based, which means their wires are able to operate at a particularly wide range of temperatures and generally exhibit solid resistance to corrosion and oxidation.

Thermocouple wire in type-K specifications will generally include a positive leg made from roughly 90% nickel, 10% chromium, and a negative leg composed of around 95% nickel, 2% aluminium, 2% manganese and 1% silicon.

J-Type Thermocouples

These are another widely used variety, although they will generally have a narrower temperature range (-40 to +750 Celsius) than K-types, and exhibit a shorter overall lifespan if regularly exposed to more excessive heat. The positive leg of a type-J unit is made from iron wire, and the negative leg will be composed of a copper-nickel (constantan) alloy.

It’s one of the least expensive thermocouple varieties, and is considered versatile, being especially well-suited to use in

reducing (non-oxidising) atmospheres and vacuums, and is ideal for taking readings from many older types of equipment as well as inert materials. However, the iron components in J-type units are highly susceptible to oxidation, and should not be used in situations where they’re likely to be at risk of exposure to moisture of any kind.

N-Type Thermocouples

Consist of wires made from nicrosil-nisil alloys (nickel, chromium and silicon), and display many similar properties to those found in K-type thermocouples, with operating temperatures in the range of -270 to +1300 celsius.

However, they’re slightly more expensive than K varieties, owing to their more recent development in order to overcome certain issues with K-types in specific environments - in particular, the type-N offers better all-round stability in nuclear applications, and exhibits lower susceptibility to oxidation than K varieties under more extreme heat demands.

T-Type Thermocouples

Temperature ranges run between −200 to +350 celsius, and it’s noted for being an especially stable thermocouple configuration, composed of copper-constantan alloy wires. This makes it ideally suited to a variety of cryogenic and other extreme low-temperature applications, including a wide range of laboratory and similar deep-freeze conditions. It functions well in oxidising atmospheres too, and is frequently used for differential measurement due to the fact that only copper wires make direct contact with the probes.
