Thank you to everyone who applied for the AX Control Scholarship.
AX Control, Inc is pleased to announce that Zaven Hamazaspyan is the winner of the 2020 AX Control Inc Academic Scholarship. This year’s scholarship is in the amount of $1,000. We chose the winner based upon the strength of a short essay. This focused on a personal account of an ambition he/she had to establish their own business, or of a small business that had impacted their life.
Due to the quality of the essays received, an additional $500 was awarded to a second student. The recipient of this award is Evan Rene MacLaughlin.
Thank you to all the students that participated in this year’s scholarship process. We received essays from around the country, including from students from Ivy League schools like Harvard, Yale, and Princeton. Applicants also pulled from other competitive schools like NYU, Stanford, Duke, and Johns Hopkins.
This article will focus on the qualities of RTDs vs Thermocouples and their typical applications and principles.
Measuring temperatures in industrial engineering is a key part of monitoring the operation of the various mechanical, electrical, and electronic systems, determining their performance, and evaluating their health.
Likewise, in chemical processes, temperature and heat control may be crucial in achieving the desired end product. Additionally, the same applies to welding, heat treatment processes, industrial ovens used for plastic shrinking, and a wide range of other possible applications. That said, measuring temperatures is neuralgic in a wide range of engineering operations, and doing so with accuracy and precision is equally important.
While there are many types of thermometers that can be used for measuring temperatures including the familiar “mercury” thermometers, the bimetallic, and the vapor pressure thermometers, those that are most commonly and widely used in the industrial environment are the resistance temperature detectors (RTD) and the thermocouple devices. Both of these thermometer types have their respective advantages and drawbacks, and they are both suitable and valuable for a distinctively different set of applications.
Working Principle of Resistance Thermometers (RTD)
The RTD temperature sensor is based on the temperature dependence of the electric resistance of metals. As the temperature increases for metal, so does its electrical resistance. Of course, there’s an intrinsic coefficient of resistance for all materials, and a positive value for this coefficient makes specific materials better than others for the measurement element role. With nickel and platinum, for example, there is near-perfect linearity that is introduced by their respective coefficients, resulting in high accuracy and precision across repeated measurements. Moreover, nickel and platinum are generally chemically stable and extremely resistant to corrosion.
If you read industry publications, you’ve probably already come across the terms digitalization and digitization a couple of times today. But do you know the difference?
It’s easy to confuse the terms. But understanding how they differ will help you gain the most information and understanding of the digital mindset.
What is Digitalization?
According to IGI Global, Digitalization is the “adoption of digital technologies to modify a business model….by exploiting digital network dynamics and the giant digital flow of information.” On the other hand, digitalization leads to the creation of a digital business. According to Gartner, this is “the creation of new business designs by blurring the digital and physical worlds.” More about this in a minute.
What’s the Difference between Digitization and Digitalization?
Digitization is where digitalization begins, in the conversion of analog data into a digital form that can be processed by a computer. Digitalization transforms digitized data through the use of digital technologies like automation, computing, coding, AI, or IoT(to name a few) to change how work gets done. And while digitization can optimize and change the process to create a better workflow, reduce costs, or minimize waste, digitalization creates a core change that affects the entire business model.
