Resistance Temperature Detectors (RTDs) are more reliable and  accurate than thermocouples. They have a sensing element which often  contains a grid of conductive film or a coil of wire. Materials to be used as sensing elements and wire materials for RTDs to select the suitable detector  The materials to […]

  In order to select the suitable detector, what materials should be used as sensing elements and wire materials for RTDs? When talking about RTDs there are three main types, Thin-film  elements, Wire-wound elements, and Coiled elements. Thin film elements  are made of very thin material, often platinum, on a […]

  Abstract  A brief description of the experiment. The abstract should not exceed four or five sentences. Introduction In your own words, explain the reason for performing the experiment and give a concise summary of the theory involved, including any mathematical detail relevant to later discussion in the report.  Conclusions  […]

topic 1: Describe three aggregate functions and provide a business example where you would want to use each function. topic 2: Explain the importance of Reports to an organization. Who typically reads the reports, and what use is made of reports? Who is responsible for delivering the content of reports? […]

ABC Incorporated is a small start-up company. The company decided to dedicate a small portion of its marketing budget and a small team of employees to build a presence on the Internet. The purpose of the website will be to offer customers information about the company and to reach new […]

   You work for Angstrom incorporated; they have a thermal control  system that has encountered a failure of a mercury-filled bulb sensing  element. There is a need to get the system up and running, but modern  regulations restrict the use of mercury sensors. Your task is to  research and persuade […]

What might be some examples of situations why we might select one mode over another?  What are some of the factors that we should consider when selecting a control mode?

  The on-off control method is the least expensive  closed loop system to use due to its simplicity. The on-off control  method does however tend to cause more wear on its equipment due to the  excessive amount of on-off cycles. It is also the hardest control system  to maintain a […]

  RTDs are more accurate and reliable than thermocouples. You should  also understand that RTD's sensing element is a resistor that changes  resistance with temperature and it is connected to the control circuitry  through a wire. Answer the following: In order to select the suitable detector, what materials should be […]

  In this week of Industrial Automated Systems we discuss process  controls that utilize variables and controlled set-points. The following  topics are part of this system: On-Off Control mode is as the name implies in that the process  control is automated to turn a system on and off. This is […]

  Abstract  A brief description of the experiment. The abstract should not exceed four or five sentences. Introduction In your own words, explain the reason for performing the experiment and give a concise summary of the theory involved, including any mathematical detail relevant to later discussion in the report.  Conclusions  […]

Describe the difference between an INNER JOIN, a RIGHT JOIN, and a LEFT JOIN. Provide a business example where you would want to use each type of join.

 Depending on the controlled variable and how fast or slow it changes,  every control system must have a controller that provides a signal to  the final control element. Keep in mind that the controller is the  decision maker that sends a signal to a final control element based on  two […]

  What is the importance of using P&ID for process engineering?    I currently work at Georgia Pacific in wood products, we make OSB. I  have worked as an electrician on shift for several years which meant  that there were several times that I would have to troubleshoot and  identify […]

 What are some of the effects that power quality might play in the  selection of different devices?  For example, power supplies may be  subject to transients, harmonics, variations in voltage and (sometimes)  frequency and so forth.  Also, what about temperature variations,  vibration, dust, and other environmental challenges. How could we […]

  Thyristors are semiconductors that are, essentially control systems  for switching and controlling power. The ones used most are  Silicon-Controlled Rectifiers (SCRs), Diode AC Switches (Diacs), Triode  AC Switches (Triacs), and Uni-Junction Transistors (UJTs). Here's a  breakdown of each one and how they function: Silicon-Controlled Rectifiers (SCRs): Three-terminal semiconductors  used […]

  Abstract  A brief description of the experiment. The abstract should not exceed four or five sentences. Introduction In your own words, explain the reason for performing the experiment and give a concise summary of the theory involved, including any mathematical detail relevant to later discussion in the report.  Conclusions  […]

What is Structured Query Language (SQL)? Describe the syntax of a query. What is the purpose of the WHERE clause in a query? Can you write a query without using the WHERE clause? Explain.

Janet is revising the website for her office at work. She wants to add a contact and feedback form to the contact page of the website. She thinks the form will bring invaluable feedback and afford users an additional method to contact the office. What are some challenges Janet might […]

  Thyristors are semiconductor devices that are used as switches to control higher-level voltages and current. Unlike variable control, thyristors have two states: fully open or fully closed. In your original post, answer the following: Discuss  the operation of different thyristors such as SCRs, Diacs, Triacs,  UJTs, etc., with an […]
