Constructed with two different materials, K-type thermocouples are sensors that are used to measure temperature.
Two wires are welded together to form a tip, also known as a junction – and this is where the temperature is measured.
If a temperature change is detected at the junction, a milli-voltage is created, which is then calculated by a temperature controller to give you an accurate reading.
They’re a vital piece of equipment in many industries, but what benefits do they have to offer?
Here’s everything you need to know.
They have a broad temperature range
K-type thermocouples can withstand some of the highest temperatures, from 0◦C to 1260◦C.
This higher range makes these temperature sensors much more useful for demanding applications as opposed to their J-type rivals.
They might be more expensive, but if you’re looking for a thermocouple that can tolerate and performs well in extreme temperatures, consider the K-type your go-to.
They have fast response times
Another thing that sets K-type thermocouples apart from others on the market is their super speedy response times.
This makes them ideal for fast-paced environments, like the medical industry for example, which rely on equipment to give a prompt, but accurate reading so that they can treat their patients as appropriately and quickly as possible.
K-type thermocouples are capable of responding to temperature changes in as little as 0.6 seconds (or 2.5 seconds for temperature changes in water).
They’re extremely durable
Due to their different metallic makeup, K-type thermocouples also excel in terms of their durability – in particular, their ability to withstand oxidation and acidity.
These temperature sensors are made from a nickel/chromium (chrome) alloy and a nickel/aluminium (alumel) alloy, which is what gives them such excellent protective properties.
This means that they’re ideal for use in oxidative or corrosive environments, and they’re much more reliable than their counterparts.
They’re affordable
Despite being slightly more expensive than J-type thermocouples, for example, K-type temperature sensors are extremely affordable.
They cost more because they are (arguably) more versatile, but through paying slightly more, you can be confident that you’ll have a reliable, accurate temperature sensor.
