  Hi I'm an HVAC tech I bump into this every other year or so. I find you class vary helpful to remember this now all I need to do is to remember how to use my meter so I don't keep blowing fuses. I did pick up a signal generator for troubleshooting.

  Our engineering department says they've found it easier to just stock lots of fuses, and accept the inevitable! :-) Glad the class can be helpful though. Keep coming back!

  As a retired electrical/process engineer and also college professor in the industrial control curriculum, I tend to watch a lot of videos like this; I am interested in what the presenters do well, and what they do poorly. How well do they address the questions from the students. Sometimes, it is obvious that the presenter has given their 'class' many times and had learned from the experience, refining how they present the information. Most of the time, it seems as if the presenter is still new to the subject, and falls into a lot of holes in trying to convey the concepts adequately. I thought this video started pretty well, but then started to fall part when students started asking questions. For example, when one student asked "what does regulating the current" mean, the presenter repeatedly tried to use the word "regulate" to define itself, which never works. When I taught this subject, I usually dealt with this question by making the points: - Without a Transmitter, we could just adjust one resistor in the loop until the desired current flows, and the Receiver(s) will 'see' the correct value. But if the loop resistance changes for any reason, or if the power supply voltage varies by even a tiny amount, the loop current will change and thus the Receiver will no longer see the correct process value. - To make the current loop reliable, able to cancel out or ignore all the odd variables in the environment or in the loop equipment and wiring, we introduce the Transmitter. - The Transmitter acts as a variable resistor in the loop, and its resistance gets changed automatically by the Transmitter in order to cause the desired current to flow in the loop, such that the Receiver(s) see the appropriate process value. But by itself, this function of the Transmitter is little better than the first rough (no Transmitter) approach. - To really make the current loop work robustly, the Transmitter ALSO incorporates its own Receiver, just like all the other Receiver(s) in the current loop. Since the loop current is exactly the same everywhere in the loop at any given point in time, the Transmitter's integral Receiver sees exactly the same current as all other Receiver(s) in the loop. Now, if the Transmitter means to have, for example, 12mA in the loop to represent a 50% process value, but some environmental change, or loop resistance change, or the power supply voltage changes, this tends to move the current away from the desired 12mA, but since the Transmitter instantly sees the error via its integral Receiver, it can tweak its variable resistance to counteract the error and get the current back to the intended 12mA. This correction happens essentially at the speed of light, so there is no perceptible delay and for all practical purposes, there never was an error in the first place. THIS is what "regulating" the loop current means.

  A pedantic comment follows 🤪. I think Ohms law is generaly presented I=V/R for showing the causality in the relationship of current to voltage and resistance. DC Current in basic terms exists as a result of voltage and resistance. However voltage exists without any current being present... So even if that presentation is algebraicaly correct, i think the original order should be kept when describing ohms law principles i.e.what is causing what and how they are related.

  Alfred, the PD6000 does not do batch control. However, the PD6210-6R2 does. You can watch an example batch control application in our video kzread.info/dash/bejne/fYJqu5iLYKyXf6g.html. We hope this helps.

  RTD is also remote thermal diode, right?

• 
  @predig Жыл бұрын

  In this case RTD stands for "resistance temperature detector". It is essentially a resistor that changes resistance predictably with temperature. It is not a diode. By measuring the resistance, one can calculate the temperature.
