A Guide to J and K Type Thermocouples

A thermocouple is a type of temperature sensor that is used to monitor and gaugetemperature. Think of it as an industry level thermometer. There are many uses for thermocouples and they are very adaptable. A thermocouple is made from two wires which made from different metals to each other and Cartridge Heaters are a UK supplier capable of providing both the J type thermocouple and K type thermocouple.

Each of the J type and K type thermocouples have their own benefits and advantages. Consider the Cartridge Heaters collection. They can meet your exact needs whatever your budget.

Uses of J and K Type Thermocouples

There are many applications for which J and K type thermocouples can be used and in a variety of industries, such as:

  • Aerospace
  • Energy
  • Food
  • Heating &Metal
  • Medical&Pharmaceutical

J Type ThermocoupleBenefits

The J type thermocouple is manufactured from both a positive and a negative leg. The positive leg is made of iron while the negative one is made of copper and nickel. A J type thermocouple can operate in temperatures of up to 750°C.

This thermocouple can be used for heat processes, which include the production of both resin and plastic. You can also use a J type thermocouple for oxidising purposes.

A benefit of this type of thermocouple it that it is durable and therefore has a long-life expectancy. It is also fitted with a strain retention coil to provide additional strength.

The level of resistance this type of industrial thermometer has to corrosion means it is perfect for use in electrical furnaces.

K Type ThermocoupleBenefits

Also supplied by Cartridge Heaters are K type thermocouples, which are produced from Chromel – a combination of chrome and nickel – and Alumel. Alumel is made from nickel, aluminium, manganese and silicon.

K Type is the most commonly used thermocouple thanks to its reliability and accuracy. This variation of thermocouples performs dependably in temperatures up to 1260°C.

If you have a low budget but still require a durable, hard-wearing cartridge heater module, then you should choose the K Type. It can be used in a wide variety of circumstances, has superb levels of corrosion resistance.

Whichever thermocouple you choose to use you can rest assured our range includes components that are capable of withstanding temperatures in excess 1000°C!If you are unsure which thermocouple you need, you can contact Cartridge Heaters to speak to their expert staff.
