Thermocouples are a vital component of different types of HVAC systems. They are sensors used for measuring temperature. At a particular temperature, thermocouples produce a unique voltage that can be measured and accordingly interpreted by using a thermocouple thermometer. Thermocouples are widely used in scientific departments as well as in the manufacturing sectors for the purpose of handling various types of control and measurement tasks. Thermocouple thermometers are frequently used for measuring temperature in kilns, ovens, diesel engines as well as in various types of industrial processes. They work because of thermoelectric effect that occurs when a conductor being exposed to thermal gradient generates a voltage. Although it is possible to calibrate a thermocouple device in a wide number of ways, there are four specific methods that are more commonly used than the others. These common calibrations are usually referred to as E, T, K and J. Each of these has a different range of temperature and an environment for which it is used. By increasing the thickness of the wire, it is possible to increase the maximum temperature that a thermocouple can measure. When choosing a thermocouple, it is necessary to follow a few guidelines that will allow you to pick up the model that perfectly suits your requirements. The temperature range covered by a particular model is one of the first things that need to be considered while buying a thermocouple. The other factors that should also be considered include sheath material, chemical resistance, as well as vibration and abrasion resistance. There are three main types of thermocouples that are widely in use nowadays. These include the grounded thermocouple, the ungrounded thermocouple and the exposed thermocouple. In a grounded thermocouple, the wires are physically attached to inside of its probe wall which facilitates in getting direct reading of the temperatures. The ungrounded thermocouple is set in isolation from probe wall, which allows for electrical isolation. The exposed thermocouple protrudes or emanates out of the sheath or the tip and so is exposed to the entire surrounding environment. What model of thermocouple will suit your purpose will depend on where you are attempting to measure temperature. It will also indicate the metal combination and the calibration that’s ideal for you. There are numerous thermocouple manufacturers in Bangalore who can provide you with the best range of thermometer products. They can also advice you about the thermocouple that will perfectly suit your needs and guide you on the various installation parameters that you need to follow. Electron system is one of the oldest thermocouple manufacturers in India, having delivered wide spectrum of products in last 2 decades.
