What is a Thermocouple and How Do I Choose One? Posted On : Dec-22-2011 | seen (208) times | Article Word Count : 402 |
Thermocouples are an extremely effective tool at measuring temperatures. However Cheap Eric Dickerson Jersey , there is a variety of different types suited for different needs and environments and so it can be confusing to know which is required. Thermocouples are constantly secretly working all around you. But what is a thermocouple and how does it work? In simple terms, a thermocouple is a sensor which measures temperature. It produces a unique voltage at a given temperature which can then be measured and interpreted by a thermocouple thermometer. They are used for a measurement and control, widely used in science and the manufacturing industry.
Thermocouple thermometers are used for temperature measurement in kilns Cheap Greg Gaines Jersey , diesel engines, ovens and industrial processes. Thermocouples work because of the thermoelectric effect, which states that a conductor generates a voltage when it is subjected to a thermal gradient. A thermocouple can be calibrated in a number of different ways Cheap Bobby Evans Jersey , but there are four which are more common than others. These most common calibrations are referred to as calibration J, K, T and E. Each one has a different temperature range and environment that it is useful for.
By making the wire in the thermocouple thicker Cheap David Long Jersey , you can also increase the maximum temperature that it will measure. When choosing a thermocouple, as with most products, it is best to follow a set of guidelines to ensure you purchase one to suit your needs. The first thing that you will want to do when selecting a thermocouple to use is to check the temperate range that it covers. You will also want to take into account the chemical resistance of the thermocouple or the sheath material as well as the abrasion and vibration resistance.
You may also want to make sure that you are aware of what installation requirements the thermocouple has Cheap Darrell Henderson Jersey , as it may be required to be compatible with existing equipment for example. The type of thermocouple is also key. The three main sub-categories are Grounded, Ungrounded and Exposed thermocouples. A Grounded thermocouple has the wires physically attached to the inside of the probe wall which can help with the direct reading of temperatures.
An Ungrounded thermocouple is separate from the probe wall, which offers the benefit of electrical isolation. An Exposed thermocouple protrudes out of the tip or the sheath and is therefore exposed to all of the surrounding environment. Various different thermocouples will offer better or more accurate readings but only in certain conditions. Therefore sometimes it may be required to sacrifice response time or speed of reading due to the requirements of the environment in which you are measuring in.
