In HVAC, you mostly find thermistors. 10k Type 2 temperature curves, from my experience, are the most common even though we don't use them where I work.
Really amazing explanation as always Real Pars! I think in the future, it would be awesome if you can make some courses using machines simulator or factory I/O simulation software.
I have one TC with range 0…to 100C. Can i change the range to -40… to 700C ?. It can be sir?, because we purchase same the specfication but wrong the range. Tks!
Hello Nguyễn Huy Liệu, Thank you for your question. As you stated you are measuring between the range 0…to 100C and are going to use an RTD of the range to -40… to 700C. Therefore, you should be able to read the measurement but as we stated in our video resistance of the RTD plays a role here. Your measurement might be off or not accurate for your application. And you might have to do some calibration to your RTD circuit device. Here is a link that might help you understand your RTD calibration requirements. There is a lot of information on the WEB that can assist you if needed. Happy learning! www.ietlabs.com/rtds.html?gclid=EAIaIQobChMIv5f7icWT_gIV0xTUAR0dSgMWEAAYASAAEgLN2fD_BwE
Hi Clement Jr, Thank you for your question! The devices we mentioned in our video are energized once power is applied to them in most cases, depending on your engineering design. And yes, you will have to write logic to interphase with these devices in your PLC to communicate with them, and in some cases, depending on the device and manufacture, you might have to create what we call a protocol handshake to start the communication as a means to energizing them to get ready. Always read the operation manual. Happy learning
