Hi Gabriel, here is the first video for this lab: ruclips.net/video/ARuhsRhCS0A/видео.html The software is from the manufacturer of the Tough Sonic LVL-100 Ultrasonic Level Sensor: senix.com/chemical-liquid-level-sensors/toughsonic-chem-10/
Dear Proff. Thank you so much for your detailed and comprehensive explanation! Yet, I kindly have this question please, which has need running in my mind since ever! If we measure the current value on the other wire going out from the Analog module, Will we get 4 to 20 mA or not ? I do highly appreciate your answer
hi pete, can i use this setup on my conductivity controller? i was planning to put a tower lamp 24vdc as an output but i wasnt sure were terminal i will connect it. BTw im using Burkert conductivity controller type 8619 thanks
HI Vignesh, Thanks for the question. The resistor wasn't necessarily needed for this portion of the lab. However, in a later part of the lab, the resistor provides the specific load so that the 4 to 20 mA DC current can flow through the 250 ohm resistor and create a proportional voltage drop of 1 - 5 V DC, otherwise we have no means to change the current signal into a voltage signal.
@@PeteVree i don't get this part. Isn't the whole point of the video to measure 4-20mA current in the circuit? Connecting the multimeter in series would achieve this easily, considering the multimeter can precisely measure mA range. What has voltage amd resistor got to do now with attempted measurement of feedback from the sensor which is in mA?
@Sgt Brown sensor should regulate how much current flows through the circuit. Short is huge amount of current in short time. But sensor that measures a quantity of something should regulate mA.
The measurement I have shown is in Series. Have a look at the video at the following link to see how you can use a Fluke 773 Multimeter to take a non-invasive measurement of the 4-20 mA current: www.fluke.com/en-ca/learn/blog/electrical/how-to-measure-a-4-20ma-loop-signal
The transmitter accounts for the increased resistance by increasing the applied voltage to the circuit to maintain a constant current that reflects the process value.
Your fine teaching skills don't go without appreciation. FYI I have a mild learning disability and your high calibre presentations are going to help me pass my construction electrician IP Red Seal exam. ( Hopefully). I've passed the Alberta provincial journeyman exam recently, but the red seal will be icing on the cake. Thanks for all of the informative links on your website as well. Nice NASA t-shirt by the way Pete.
Yes. Often an Instrumentation Tech. will be carrying a multimeter similar to this one: www.fluke.com/en-ca/product/calibration-tools/ma-loop-calibrators/fluke-789
What is the name of the software used to show the current measurements on the PC?

Thanks a lot, Pete!!!
thanks alot, Pete!!
That is the best Electronic Instrumentation workshop I have eve seen . Thanks for sharing. Toronto is awesome!!!!
Dear Proff. Thank you so much for your detailed and comprehensive explanation!

I do highly appreciate your answer
thanks!! this video helps me alot.!
why is it that everytime i try to do troubleshoot sensors on site i get like 0.08ma reading but 90%RH (0%-100%) on a 4-20mA input
Hlo, why u didn't connect the + mA to Fluke's 400 mA terminal directly..Why you short it with other lead wire?
That jumper has a 250 ohm resistor that I use to demonstrate to the students how to change a 4 to 20 mA signal to a 1-5 Volt DC signal

THANK YOU for sharing your knowledge❤❤❤
please make more educational video ❤😊
Why the resistor needs to be connected?
Sorry for the dumb question.

@@PeteVreeI was confused by that as well.
Is it possible to measure 4-20ma in parallel in ultrasonic transmitter

@@PeteVree thx sir
Hello, can you share the location of the training center ?
We are located in Toronto, Ontario, Canada
I provided more information in response to your email. All the best Mario.
nice and easy. good job.
If you add a resistor wouldn't that change the amps that you read at your meter?
The transmitter accounts for the increased resistance by increasing the applied voltage to the circuit to maintain a constant current that reflects the process value.
Pete Vree thank you Pete, great videos I've learned so much from you much appreciated!
how to test it on the field
Thanks Pete.
There should be free t-shirts after every 50 views. Glad your enjoying the videos.

Good luck! Here in Ontario we just write once and if you get above 70% you get your Red Seal.
Thanks bro it was helpfull
So is it possible to measure any 4-20 mAanalog output signal (such as positioner, transmitter) ?
Yes. Often an Instrumentation Tech. will be carrying a multimeter similar to this one: www.fluke.com/en-ca/product/calibration-tools/ma-loop-calibrators/fluke-789
Why don't you say simple that u connected Ampere meter is connected in series
I did. It just took me 9:37 to say it.
