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 be used as sensing elements for Resistance  Temperature Detectors (RTDs) include platinum, nickel, copper, and […]

   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 management to pick from the many modern electronic  thermal sensing elements. The sensing system to […]

  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  This section  should reflect your understanding of the experiment. Important points to  include are a […]

  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 dependent on  input variables and does not have a mechanism to account for lag. On-Off […]

  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 used as sensing elements and wire materials for RTDs? How are thermocouples types and temperature […]

  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 consistent process variable because the tolerances are  expanded to avoid starting and stopping of the […]

  Find an example of “back to the drawing board” due to design failure  or the need to improve a design. Summarize the issues you found. Hello, This might be one of the most “back to the drawing board” inventions  there is. Some historians believe there are over 20 inventors of the  incandescent lamps up to the point of Edison’s version. Many of these  inventors […]

  Construct the Multisim circuit shown in Figure 2 (top) using components listed in parts list for J-K flip-flop. Change inputs preset and clear as shown in Figure 2 (bottom) and observe outputs Q and Q’ using digital probes. Write down results using Table 3. J-K flip-flop: 1 – J-K flip-flop 1 – 1 KOhm resistor 2 – SPDT switches (to control preset and clear […]

  Discuss the difference between latches and flip-flops: The biggest difference I took away from latches vs. flip-flops, is  that a latch does NOT have a clock signal, but a flip flop will always  have a clock signal. Another difference between the two is that latches  are “asynchronous” and flip-flops are just synchronous.  (dept-info.labri.fr) This means that for a latch, when an input signal  is […]
