    Thank you, sir, for explanation and great labor!
    However I am still confused with some designation, especially in mining field instruments. I mean, I have no idea how to name, for example, bearing temperature sensor or belt misalignment sensor.
    Unfortunately ISA doc doesn't list a plenty of different functional elements.

    • @jtodora
      @jtodora  3 роки тому +1

      There isn't, or a least wasn't any standard. People migrated toward ISA simply because they are attempting to define a standard. You can certainly create your own symbol and nomenclature. Just be sure to create a key on the drawing that shows and defines to the reader what you've done.
      I've seen many user defined symbols over the years, especially in the biotech field. Again...just make sure you include a key on the page to inform the reader what the new symbol is and how to read it.
      Thanks.

    So the undefined signal means that the signal type is unknown ??

    • @jtodora
      @jtodora  2 роки тому +1

      Thanks for watching. An undefined signal is exactly that, a signal that does not have a symbol in the standard ISA library of signals. Therefore, if you have a process that has a signal that is unique and does not have a defined symbol, use the undefined signal and reference what type of signal it is in the key on the drawing. I hope that helps.

    nice explanation and very slow paced that make sure you understand ever little detail
    however one thing i want to ask is
    you said go to black board then documents to find the standard
    so what is blackboard ?

    • @jtodora
      @jtodora  4 роки тому +1

      Hi, You won't have access to Blackboard. This video was used in a face-to-face class I taught at a local community college. The college uses a Learning Management System (LMS) call Blackboard where registered students can find the course materials. The documents that I reference can be found on the Internet with a little searching. I'm not sure where you are located, so make sure that the ISA standards are used in your location otherwise the documents will not be much use to you. Thanks for watching and I'm glad if it helped.

    Can u please explain types of loop in p nd. As u explained in the end of this video like pneumatic control loop n electronic control loop. I want to know total types of control loop in p n id with one example of each. I will be grateful sir for my entire life. Please🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏 sir. I m from India. Please sir

    • @jtodora
      @jtodora  4 роки тому

      Pdms Caesar. Pneumatic and electronic technology are not control loops. They are technologies used for the instruments in a control loop. As an example, pneumatic is equipment and instruments that operate using compressed air or in most cases nitrogen. They are rarely used anymore because they are very slow responding. They're primary use was in area's where there was a spark hazard from electronic control, but even that is not an issue anymore. Electronic control is exactly what it says. The equipment and instruments use electronics. Most of the time they operate on a 4 to 20mA signal or a 0 to 10Vdc signal. They are fast and very reliable. There is also mechanical. If you think of something as simple as a toilet tank. This is a mechanical control system. As the water rises in the tank it lifts a float. The float is attached to a lever that raises with the float. The other end of the lever is attached to a valve actuator that closes the valve. When the toilet is flushed, the level decreases, the float drops, the lever rises and the valve opens to allow water to fill the tank. If you do a web search, you can see examples of all of these technologies. There are also many good UA-cam video's that demonstrate these concepts. I hope this helped?

    What’s does discreet instrument mean

    • @jtodora
      @jtodora  2 роки тому

      Thanks for watching. A discrete instrument is an instrument that is detached from other instruments in the process. As an example, a discrete instrument could be monitoring the pressure in a vessel. The discrete instrument, a pressure transducer/transmitter, sends the pressure reading to a shared control instrument that then displays the pressure. In other words, it is a stand alone instrument that has to send it's data someplace to be read. I hope that helps.

      Sorry, but I can't make people post comments. Also, the study of valves is HUGE. Way too much to post in comment area. Please check out the International Society of Automation (ISA) at isa.org They have lots of information on all types of process control topics. There is a fee to most of their materials; however, they literally wrote the book instrumentation and process control.
