SR540 (or SR800) Coffee Roaster Thermocouple Installation
HTML-код
- Опубликовано: 16 сен 2024
- In this video I show how I installed two thermocouples in the SR540 coffee roaster and connected them to the Artisan Software. This setup also works for the SR800, although you might consider a longer Bean Thermocouple.

Why would someone give this a thumbs down? There is good information here and a bunch of links in the description so why wouldn't they like it? Very strange. Anyway, I liked it and appreciate it.
Thank you very much for your comment and feedback.
Thank you for making such an easy to follow and comprehensive video series on this. I just purcharchased a SR800 and I am going to use this as a guide to set mine up for Artisan.
You are welcome! Everything should work on the SR800, just make sure the bean thermocouple is long enough.
Great and informative video. Thanks for taking the time to put this together!
You are welcome! Thanks for the feedback.
Thanks for doing this! I'm just starting out on an SR540 and the video gives me a quick primer. If you still are on RUclips I'd be interested in hearing whether you're still using it and experiences you've gained.
Cheers
This was incredibly helpful. I have an sr800 and have been interested in doing this mod. Thank you 🙏
I am glad this was helpful. This should work on the SR800, just make sure the bean thermocouple is long enough.
@@coffeeroastingathome8890 which long is enough for Sr800? Thank you!
@@adolfoperez1312 I don't have the SR800, but check that the thermocouple tip is inside the beans when approaching first crack. The exact elevation is not very critical.
Very interesting that the ET tracks the BT so closely. What would be interesting on the SR800 is how closely the ET/BT tracks with the built in thermometer below the bean chamber. This might provide users with additional information for controlling their roast.. If that thermocouple tracks closely with the BT, would be a nice evolution to tap into this thermocouple.
Thanks for posting this video.
anyone wanting to simplify this can use the temp probe on a Weber iGrill BBQ temp sensor and export the data to an excel spreadsheet. Graphs are easily made in the spreadsheet. You can save time/fan speed/power levels and graph airtemp/probe temp vs time.
bravo!
Great job thanks
Thank you too!
Thank you for the videos you posted. All are very interesting! I was wondering how you were able to control the speed and power of the 540 from the Artisan dashboard.
I just realized after watching your other video again that you were not controlling the speed and power with Artisan --you were marking your profile with the sliders after manually changing the speed and power on the SR540. Is that correct?
Hi Chris, yes this is correct. I make the changes manually in the SR540 with the knob, and then move the slider in Artisan to match the SR540 setting. I do this only to keep a record of the setting changes I made during the roasting for future reference, but you have to remember to adjust the sliders every time you make a change in the SR540. It would be nice to be able to control the SR540 directly from the Artisan sliders, but that will require modifications beyond my skills. Thanks for your feedback!
Hi, first off, this video and your other one is fantastic. I wouldn't have been able to set it up without this. I've used your set up on my artisan profile, but the one thing I can't figure out is how to get the step visual of the change of the Air and Burn. I know how to configure and add them to the chart, but mine just shows up as small blips on the bottom of the chart. It's as if the scale is off or something. Thoughts on how to fix the configuration for that?
Thanks for your feedback, I appreciate it and I am glad they were useful. About the visual indication, in the menu Config-Events-Sliders, make sure the Min and Max for the Air and Burner are set to 10/90, and click the "Coarse" checkbox. Offset should be 0.0 and Factor 1.0. I hope this helps, you can also download the configuration file and use that.
I am setting up my sr 800 with thermocouples. I have ordered a 300mm probe for the bean probe. I am having difficulty determining where the end of the probe should be in relation to the green beans. Is it ok if the end is in the bean mass at the start of the roast or should it be above the beans? I also am using the extension tube. I have searched high and low and can't find the answer to this. Your videos have been a great help in setting up the artisan software.
Yes, it is OK if the tip of the thermocouple is in the bean mass at the start of the roast, an inch or two away from the bottom. The exact position is not too critical, as long as it is repeatable between roasts.
@@coffeeroastingathome8890 Thanks , this coffee roasting is more complicated than I thought it was going to be. It's fun though!
great video. so for BT you would suggest to get a thermocouple that's longer so it would stay touching the bean mass but no to the point where it would touch the bottom where the heat is coming in right?
Thank you! Yes, that's right. I made another video with an extension tube and a longer thermocouple inside the bean mass, you can check it at: ruclips.net/video/xo9IdakyIqw/видео.html
Thank you for making this video. I am wondering if you plan to use the extension tube on your SR540 since they seem to provide a more even roast and more intimate with the air flow. If so, could you still use both therocouples?
Yes, I have been using the extension tube with a longer bean thermocouple probe (and the same environment thermocouple). I am working on a demo video using the extension tube with the details.
You mention the idea of only using the ET sensor. Have you noticed if it reads much differently than the temp sensor built into the sr540?
The built in temperature sensor measures the inlet air temperature, before it interacts with the beans. The beans exchange heat with the air and also release steam, changing the air temperature in ways that are difficult to correlate closely with the inlet air temperature. The built in temperature sensor reads generally quite a bit higher than the ET sensor, and the temperature changes when changing settings are much more abrupt. Hope this helps!
I have the air and power settings showing on the left side of the Artisan graph like you do, but they do not change when I change the settings on my SR800. What do I need to do to get them to show the proper settings? Thank you
You need to click and drag the slider to match the settings in the SR800 roaster. There is no communication between artisan and the roaster settings, so artisan has no way of automatically knowing what settings you have in the roaster. The sliders are intended to keep a record of what you do (like writing the settings in a piece of paper, but more convenient).
What was the cost of each component?
I just sr 800 roast with probe thermocouple 11(ET)cm and 20cm(BT)? is that ok?
Hello, I don't have an SR800 so I am not sure. As long as the BT is close or within the beans mass when roasting, you should be fine. The exact position is not very critical.
Very nice of you to show how this is done. I am wanting to do this to my sr800 with the Razzo extension tube. If you are so inclined perhaps a video of an actual roast or two. I am a beginner to this and have been lucky that my first roasts were actually good! Again, thank you very much for this excellent video. (You might want to post this on Reddit.com/r/roasting)
Thank you! This setup should work on the SR800, just make sure the Bean Thermocouple is long enough. I did post a video of an actual roast (the link is in the Description of this video), hope you find it useful. I am also now roasting with an SR540 extension tube and may post a video of that in the future. Thank you for the tip on Reddit, I wasn't aware and will check it out.
@txaggieaero Good luck with your setup, sound interesting. I have a Raspberry Pi running PiCorePlayer and Logitech Media Server for streaming high resolution music, works great.
@@coffeeroastingathome8890 did the thermocouple fit well with the extension tube?
@@timothyhawkins9469 I had to replace the bean thermocouple with a longer one for the extension tube. I am putting together a video to show that change and a roast demonstration with the extension tube.
@@coffeeroastingathome8890 did replace with the 20cm? I was looking at that possibility and plan to try the setup soon. Thanks for the reply.
