Sorry i didnt understand your question.

Oh i see, this is just an old card i had😅 great you noticed! At the end of the video you can see actual 4AI cards i used for a project :)

Hi, veey simple. If you heat up the sensor and resistanse go up = ptc If you heqt up the sensor and resistance go down = ntc

Hi, its very depend, when installed correctly, avoiding mechanical and environment damage, lifetime of a pt100 can be up to 20 years. I have pt100 sensors in my factory that are still working after 15-20 years.

Hi, thanks for the comment. I generaly quit posting videos because its hard to get to many people. If you have any question or need help with any equipment ill be happy to help

Hi, Its excatly as you saied. Every controller can be calibrated. For exsample you can calibrate to get 4mA in 0c, and 20mA in 200c. Ofcourse the controller needs to have an analog output for this. The controller i use in the video dosnt have an analog output. So you dont have any 4-20mA to calibrate. You can only use it for dry contacts and temperature reading

@@btoash So do i need to allways have a special RTD card or dies pt100 work on normal analog input card? Its resistance reading so it must be RTD card right?

@@genantamtam9364 If you use a pt100 card, then yes, you must always use a pt100 card. In my video, i use a 4-20mA analog input card, not pt100 card, because i have a transmitter between the pt100 and the AI card

@@btoash so you mean if i have only a pt100 then i need to connect pt100 directly to a RTD card. But if use a transmitter in the middle (that convert resistance to mA signal) then i need to use normal 4-20ma analong in card?

@@genantamtam9364 you got it right. When you have a 4-20mA card, then you can connect to your plc different kind of rtds (pt100, ntc etc) by using the right transmitter

Hi my friend. first of all, let me clarify for you, there is different transmitters and controllers for different types of temperature sensors. if you like to use pt100, you take a controller that is suitable for pt100. if you like to use NTC, then you take a controller that is suitable for NTC. you cant take a PT100 sensor and connect it to a thermocouple transmitter (for example). there are controllers that have a few inputs for different temperature sensors, but that is also need to be specified in the data sheet of the controller. when you choose to use a controller for PT100 or NTC or what so ever, if you choose the right controller, there is no need for calibration because this is standard well known sensors, and they are already calibrated. in some industry's, like food industry or pharma, then you need to check the calibration of the controller every period of time. in case you find a error, in every controller you can calibrate and "fix" the temperature to the actual reading (every controller should be calibrated using manufacture manual) hope this helps you

@@btoash Thanks

Hi my friend, Actually no, you can use any electrical wire you want. No problem at all

Hi, the 2 wire transmitter is called a "passive" transmitter, this type of transmitters get power supply from the analog input wires (24vdc). When you use an "active" transmitter, you have to give the transmitter an external power supply. Hope its clear now

@@btoash thanks

Thank for the comment my friend. But actually i am working with rtds for 10 years now, and never had a problem measuring resistance with my hands.

Thank you so much for your comment, i really appriciate it!

Thank you! Hope you enjoy

You probably dont give a damn but does anybody know of a trick to log back into an Instagram account? I was stupid forgot my login password. I would love any tips you can offer me.

@Kash Trevor instablaster =)

@Sylas Houston thanks for your reply. I got to the site thru google and I'm waiting for the hacking stuff atm. Looks like it's gonna take a while so I will get back to you later with my results.

@Sylas Houston It worked and I actually got access to my account again. Im so happy:D Thanks so much, you saved my account :D

Thank you my friend!

thank you! there is informetive videos i post every few days. if you like to subsribe :)

@@btoash I subscribed

Thank you for the great comment! Ill check this out

Some training and few exsersices and you can :)

That a way to do it though:D

Glad you get insperation from this :D

Thank you!

Thank you for your comment, realy apriciate it! Ill try to improve to quality in the next video, but some of the videos were filmmed with bad quality from the begining. These are some videos sent to me, its not mine :)

Your very welcome my friend! Take care and God bless! Animal Papa! 🐾🙏

Thank you very much my friend!

Thank you for your comment! I realy appriciate it

Thank you! By the way, im also an electrician ;)

@@btoash Glad to hear that!

Thank you! You two!

Thank you very much!
