What are thermocouples? Why Use Them? How Do They Work?
What is a thermocouple? A thermocouple is a sensor for measuring temperature. sheath materials are also available. View our range This sensor consists of two dissimilar metal wires, of high temperature exotic thermocouple probes. joined at one end, and connected to a thermocouple The tip of the thermocouple probe is available in thermometer or other thermocouple-capable device at three different styles. Grounded, insulated and the other end. When properly configured, thermocouples exposed. With a grounded tip the thermocouple can provide temperature measurements over wide is in contact with the sheath wall. A grounded range of temperatures. junction provides a fast response time but it is most susceptible to electrical earth loops. In insulated Why use a thermocouple instead of a RTD junctions, the thermocouple is separated from or thermistor sensor? the sheath wall by a layer of insulation. The tip of the thermocouple protrudes outside the sheath Thermocouples are known for their low cost, durability wall with an exposed junction. Exposed junction and versatility as temperature sensors, therefore they thermocouples are the fastest responding and best are commonly used on a wide range of applications suited for non-corrosive gas and dry air temperature - from heavy industrial and process industry usage to measurements. laboratory and environmental testing.

A thermocouple probe consists of When two wires composed of dissimilar metals are thermocouple wire housed inside a joined at both ends and one of the ends is heated, metal or ceramic tube. The wall of there is continuous current which flows in the the tube is referred to as the sheath thermoelectric circuit. If this circuit is broken at the of the probe.

What are thermocouples? Why Use Them? How Do They Work?
Different combinations of metals Thermocouples are available with different transfer from the outside, through the probe wall combinations of metals, known as types or to the thermocouple junction. In an insulated probe, the calibrations. The most common are the “Base Metal” thermocouple junction is detached from the probe wall. thermocouples known as Types K, J, T, E and N. Response time is slower than the grounded style, but the There are also high temperature calibrations - also insulation provides electrical isolation. known as Noble Metal thermocouples - Types R, S, C, Pressure Manufacture D and B.
Common Thermouple Temperature ranges
Each type has a different temperature range, tolerance and environmental considerations. Although the thermocouple type dictates the temperature range, the maximum range may also be limited by The thermocouple in the exposed junction style protrudes the diameter of the thermocouple wire. That is, a very out of the tip of the sheath and is exposed to thin thermocouple may not reach the full temperature range. K Type Thermocouples are known as general the surrounding environment. This type offers the fastest purpose thermocouples due to their low cost and wide response time, but is limited in use to noncorrosive and temperature measurement range. non-pressurized applications. See the illustration above for a full discussion of junction types. The sheath insulation is sealed where the junction extends to prevent penetration of moisture or gas which could cause errors.
