Thin-Film Resistance Temperature Detectors

Current Advances In Process Temperature Measurement: Trends And Technologies

Thin-film resistance temperature detectors are devices that are used in measuring temperature in Chemical process industries. The temperature measurement device is important since it improves the processes in chemical industries. Therefore, it used in critical parts of processing, for instance, it is used in measuring temperatures in the reactors, boilers, heat exchangers and evaporators processing. The market for these technologies continues to revolutionize due to technological advancement. At a personal level, one can use a portable mercury temperature sensor as a device used for noting temperature changes. They help create health awareness for an individual who uses them; thus, they help individuals make healthy decisions and deal with temperature-related issues. After the time, the temperature is the second most measured data. Therefore, the measurement of the temperature goes way back to the 2nd Century. Therefore, people have already known that expansion occurs due to heat while contractions occur due to cold. The technological growth of the devices used in measuring temperatures has experienced rapid growth over time. In the year 1998, the most common temperature device used at the time was mechanical type sensors. The mechanical temperature sensor depends on the expansion and contraction of liquid, solid or gases substance to determine and measure temperature changes. The most common mechanical temperature sensor is the mercury temperature sensor since it uses contraction and expansion of liquid to show changes in temperature. But for the purposes of this discussion will use the thin-film resistance temperature detector technology.

The most measured variable in chemical process control is temperature. Therefore, temperature devices revenue is approximated to be $400 million and 30% going towards chemical process industries in the United States alone (Cushing, 2017). Over the years, the chemical process industries have experienced technological advancement in sensors. Due to accuracy issues, cost, and high maintenance costs, industries have shifted to using resistance temperature detectors (RTDs) instead of the commonly used Thermocouples (T/Cs). The development of the RTD technology will enable users to measure the temperature values accurately. Also, the technology offers more stability. The thin-film RTD technology development has the desire to reduce costs and improve operations (Cushing, 2017). Therefore, the technology will replace the use of T/Cs and also increase the availability of temperature-integrated assemblies. The new technology is designed to solve problems associated with the temperature process in chemical process (Cushing, 2017). The technology will help in decrease wiring costs, reduce hardware and increase efficiency and accuracy, easing future upgrades and also help in simplifying engineering by preventing wiring mistakes.

In the process of RTDs, in order to achieve ultimate accuracy, the user can depend on two available options. First, for sensor matching from the RTD, you can use Callendar-Van Dusen (CVD) data, and the second one can change CVD data to avoid errors in the transmitter (Cushing, 2017). This technology offers high-accuracy RTD and includes:

• Choosing the element results in high-purity platinum, which ensures the highest accuracy and stability.
• Also, it has the ability to reduce self-heating effects.
• RTD is not connected to a specific transmitter. This aspect ensures RTD, transmitter and sensor are flexible.
• Increase time efficiency.
• The technology reduces and eliminates the costs related to VCD calibration.
• The technology offers the best accuracy and reliable point of measurement.

We forecast that by 2019, the technology behind the resistance temperature detectors will gain market attraction and penetrate the market by approximately 30%. Also, the technology would have been modified to improve its accuracy level. Thus, the accuracy level of the technology would be modified up to 99.9%. With already in use in the market, the technology will help in addressing the problems with existing processes of temperature measurement in the chemical process industries. With the growing popularity of the technology in the rise, the chemical process industries will be able to reduce the costs associated with the existing process of measuring temperature. By 2019, most chemical process industries in the business, especially in the United States, will have incorporated the technology into their process system. Also, by 2019 will see the RTDs technology being used in different chemical processes.

Also, the technology will help in decreasing wiring costs, reducing hardware and increasing efficiency and accuracy, easing future upgrades and also help in simplifying engineering by preventing wiring mistakes. We certain this level of uncertainty as relatively certain because the technology is already in uses and because we have seen an increase in demand for advanced technology before.
