There have been many developments in the temperature sensing industry over the last century and one of them is the development of different thermocouple types. These devices are used to measure temperature. The sensor has two conductors that are made from different materials. When these conductors are placed in two environments with different temperatures, a potential difference is created. This voltage is directly proportional to the difference in temperature.
Thermocouples have become very popular in industry because of a wide range of reasons. For one, they produce an electrical signal, which makes them suitable for use in industrial control processes. Secondly, they have a wide temperature range. This means that they can be used to measure both low and high temperatures. They are also very accurate, thereby making them suitable for industrial feedback control processes.
Since the conductors are metallic, these sensors can be used to measure temperature in areas where temperatures are extremely high. They can also be immersed in dangerous chemicals and gasses to measure their temperature with little effect on the sensor. These properties have made them suitable for a wide range of industrial applications.
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.
The following are types of thermocouples that can be found on the market today; type N, J, E, M, C, T, S, R, B and K. These devices have different applications because their temperature ranges are not the same. This is because their conductors or junctions are made from different alloys or metals. The specifications of a thermocouple must be considered by the buyer when making a purchase.
In order to determine which thermocouple types are suitable for certain applications, you need to do some research. For instance, you should know the maximum and minimum temperatures in a process. You also need to know about the nature of chemicals and gasses that will be in contact with the temperature sensor. If the entire control process is based on temperature changes, you need to consider the tolerance of a sensor before you buy one. In industries, engineers are normally responsible for choosing such devices, so they should always be consulted.
