Different thermocouple types have been developed over the years due to the search for the perfect temperature sensors for different conditions. Thermocouples are metallic temperature sensors that generate an electrical potential difference when the two junctions are subjected to different temperatures. This potential varies proportionally to the temperature difference between the two conductors.
One of the main reasons why thermocouples have become very popular in the industry is the fact that they produce an electrical output, which is very easy to use in process control. They also measure a very wide range of temperatures. Their accuracy plus the fact that they are affordable make these devices suitable for a variety of industrial applications.
One of the main advantages of using these devices is that they can be used in furnaces and boilers to measure very high temperatures. This is because their junctions are metallic. Sensors that have corrosion resistant junctions can be used to measure temperatures of dangerous chemicals and gasses. These are just some of the characteristics that have made thermocouples the preferred temperature sensors in industries.
Alumel and chromel alloys are used to make type K thermocouples. These are the most popular types of temperature sensors in the industry. The devices can measure temperatures as high as 1350 degrees Celcius, and as low as -200 degrees. While most thermocouples are made of platinum alloys, there are many others that are made of chromium, nickel, aluminum, silicon and manganese alloys.
Thermocouples are normally exposed to very harsh conditions that may corrode the conductors very fast. For this reason, these sensors need to be replaced on a regular basis. This will ensure accurate measurements are always taken for process control functions among other uses. Even if there is no wear and tear, the sensor still needs to be re-calibrated to maintain the integrity of measurements.
Thermocouples are very cheap. Compared to other temperature sensing mechanisms, these devices are more affordable. This makes it possible for companies to replace them on a regular basis without feeling the pinch. When replacing a corroded sensor, it is important to ensure that the specifications of the new device matches those of the corroded one. Alternatively, you can just refer to the manual of a machine before replacing any component.
In manufacturing, processing and assembly industries, type B, N, J, K, T, S, E, M and R thermocouples are the most popular. They are used in different areas because they have different temperature ranges. The two junctions in a thermocouple are made from different alloys or pure metals that have a very high melting point. Some of the most important factors to consider when looking for a temperature sensor include accuracy, tolerance and temperature range.
A lot of research needs to be done in order to determine which thermocouple types are suitable for a particular application. The research should aim to identify the range of temperatures in the process, type of chemicals or gases that are in the process and the desired accuracy. This will make it easy for you to choose a suitable temperature sensor that will operate efficiently when subjected to different temperatures. Normally, engineers and technologists are the ones who determine the best temperature sensors to use in a factory.
