The Engineering Mindset Hi, i’m a fan of your videos, I’ve been watching them to get through school and they’ve really helped me understand things so thank u, but I was wondering whether u could do an explanation on the differences between conventional current and electron flow? Like are they the same thing cause like u said current is the flow of electrons in a circuit and and they flow from the negative terminal but conventional current flows from the positive terminal then soo??
This is a great explanation. None of our engineers (including me) knew how the K-type thermocouples we use at work function. Now I know why I get such different readings when the thermocouple is hooked up to the wavelogger backward.
In hvac school online and they just say here read this after working 12 hours I was struggling at night trying to read like becoming cross-eyed and falling asleep. This video just condensed two weeks of reading into an interesting informative video thank you!!!
I would like a video on pyrometers also. I work with thermocouples and RTD's everyday and being an electrician I understand them but I also work with pyrometers which I dont understand. I was pushed into a facilities eng. job at a ceramics company and find myself lacking in knowledge of extreme heat. They cook stuff at temps I didnt think possible like 3300C. Glad I was pushed. Never loved a job before this one.
alot of his vids helps me with basics knowing and more advanced, working as an marine electrition, ive never studies cause i cant afford it, still live with my parents, but using your pdfs and vids to help myself understand what im working with and how it works, thank you🙌
Great video! Quick question though, if RTDs are medium to high cost why would they be used on a thermocouple which is lower cost? Seems like you could just use the RTD and call it a day
Great video !! it really helps to know about the basics of temperature sensors. Could you give details about the advantages and disadvantages of each temperature sensor?
Hey, I did not understand the difference in working between the metal/conductor atoms and semi-conductor atoms. Why is one a PTC type and the other NTC type? Both ways of working are similar. Both must have increasing resistance to current flow.
I think it has to do with the materials used. I don't have any reference other than what I read on DigiKey, but I think NTCs use metal oxides while PTCs use, I think, ceramic stuff or polymer, can't remember. I'm not a chemist so I couldn't explain why this would affect its behavior
@@abhinandanawasthi3814 you have to touch both the wire and the track to complete the circuit, just like the train. but that will also kill you so don't do it.
Can you please have a video locating the balancing valves, differential pressure sensors, differential temperature probes and how sequencing of chillers and pumps are done. Basically the sequence of operation of the system with an illustration would be very helpful with all the parameters.
@1:57, ok the two different metals react differently to temperatures, but they are tied together, and thus shorted out....so how is there still a voltage difference???
Suppose I want to measure the temperature of air in my compressed air system. Doesn’t need to be super accurate or have high resolution. I’d like to insert something into a copper tee fitting at various places and read the temperature. What would I use without breaking the bank? Thanks
Hi Thank you for the video, great content. Is there a kind of thermal sensor just turning on or off following if we get below a temperature or above a temperature ? I struggle to find this kind of components. I dont want in my application what is the temperature between A and B. But just to know if the temperature is below A or above B. Thank you very much ! Ed
@@garrysekelli6776 According to the Google definition, "a device that converts variations in a physical quantity, such as pressure or brightness, into an electrical signal, or vice versa." Hence, why a better, animated explanation would be helpful.
OMG! This was super helpful, I had a superficial understanding but this helped me go a bit deeper so I now what I am seeing and reading. Thank you so much!
Hi! There is something i'm looking into right now that seems to be generally overlooked: When you have radiant heating sensors should be covered by a "black bulb". I cant find a good explainer video showing the difference between operating a radiant heating system with a regular temperature sensor and a black bulb sensor.
It's a real pain when TCs fail too because they can fail in a way that is very subtle at first so anytime a negative temp trend occurs everyone wants to blame the TC first.
I love the channel. Best channel I have subscribed to. Thank you for starting this. I enjoyed this video in particular but you didn't talk about infrared sensors.
Great video we love temperature sensors, great timing. We use these sensors in our titanium oxidize, we just call it anodizing and in power coat baking oven set ups controlled temp and heated liquids required for best results and it is nice to learn more about them here. Thank you. Lance & Patrick.
Brother can you help me my chiller tube is leakage . now I got water inside the shell how can I remove that water from the shell . Can you explain to me in video .
You need to contact a specialist refrigerant recovery company in. The chiller will be contaminated with moisture and need to be treated, new oil and filter driers. The tubes tested and repaired, you might be able to plug the tubes if not many. Speak to the manufacturer
@Engineercan i tell you what it is loke to have your ide. M noty stolen fkr fools like you to to know a little more about policies that you sighned up for but I didn't know that a person on. Here didn't without asking me
I have a problem I have tried to solve for years. Controlled from a computer, control at least 32 (off/on) switches, isolated, with a possibility of an acknowledge line back to the computer. What circuit will do it?
Top of my head I'd say use a raspberry pi to control an IC chip and piggy back more off that to give you 32 on/off points. Can then use relays off those to control larger circuits
Very good video 👍👍. But another important Temperature sensor used in large scale manufacturing plants is Gauges (Bimetallic strips connected to Pointers)which show accurate measurement without the need for any electrical input or measurement technique. Maybe you can cover a short video on those along with their applications on Thermostats
THANK YOU so much! I am a mechanical engineer and still had not understood so well the differences and working principles of each sensor. . Your 10 min video was so much more efficient than the 6h throughout 2 weeks that my professors spent trying to explain the same topics to the class. . Even so most of us could not understand 100%, but now it is crystal clear
