So simple, detailed, bewitching explanation with no rush. Watched too many PID , but this is the best. Enjoyed it. Congratulations. Respect for labor.

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.

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.

I will always be grateful

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.

How would you know what valve to used at what place

@jtodora

2 жыл бұрын

It all depends upon the application, the type of material that is is being piped, the amount of flow, pressure, etc.

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

@jtodora

Жыл бұрын

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.

What’s does discreet instrument mean

@jtodora

Жыл бұрын

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.

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 KZread video's that demonstrate these concepts. I hope this helped?

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.
