Thermocouple Types And Their Specific Applications

by Lenore Bolton

Thermocouple types refer to devices used in measuring temperatures and they are of different types. Principally, these devices are composed of two metals of different materials, which are normally joined at one end. When the junction is either cooled or heated, a voltage is produced, which is subsequently used to tell the temperature of materials.

Normally, there are about four variations of these devices, and the difference is brought about by the different combination of calibrations or metals. The standard categories of the most common calibrations are given as J, K, T and finally E, although there are some with higher calibrations of temperature and are given as R, S, C and GB. Generally, each calibration will have its own range of temperatures, but the maximum temperature is hugely dependent on the diameter or thickness of the wire that was used in the thermocouple. What this means is that a thermocouple will not reach its maximum range if it is made of a very thin wire.

These devices for measuring temperatures come in three major varieties, the first of which is the beaded wire thermocouple. It is composed of two wires which are joined together by a welded bead. The fact that the beads are exposed makes it have several limitations in its uses.

It is not suitable for use to measure the temperature of liquids, which could oxidize or corrode the alloy of which it is made. In addition, measurement is compromised by its indirect connection with a metallic surface. In short, this temperature-measuring device is only suitable to measure the temperatures of gases.

The other variation of these kinds of measuring devices is the thermocouple probe, in which there are two wires sheltered inside a metallic tube. The metallic sheath is most commonly made using either stainless steel or iconel. Normally, iconel can support a very high temperature range; however, stainless steel is preferred to iconel because of its wide compatibility with chemicals.

When you are in search of the <A href="http://www.stimfg.com">thermocouple types</A> you will get that which has been, exposed, grounded or ungrounded this grounded, probe type has wires that have been connected inside the probe wall. This type works well in that it allows the heat to be transferred from exterior to this probe . Wall and be directed to the thermocouple. When this thermocouple is not attached directly to the probe it means that the probe is ungrounded. But when it is not attached this is supposed to mean the time for response is slow than that of grounded style on the other hand the ungrounded type of thermocouple can give electric isolation

When choosing the type that is suitable for measurement of specific substances, it is important to consider important factors such as range of temperature of a given device. Checking the chemical resistance of the device or the sheath material used to make it is also important. Finally, it is advisable to consider its level of resistance to abrasion and vibration, and more importantly, the installation requirements.

It is also of significant importance to know just the right type of junction to go by and they normally come in three groups: exposed, grounded and ungrounded. These types of junctions are important in their own ways as some offer excellent response time while others will give good electrical isolation. In short, when it comes to <A href="http://www.stimfg.com">thermocouple types</A>, one need to choose according to what they will use it for.
