Works beautifully with Aspar 1TE mini modbus thermocouple amplifier (thermocouple K-type) 🙏 thanks a lot!!!! |
Thank you for sharing this intel from Downrange. I am not sure if we are allowed to post commercial links here. I really like to know your source for purchasing it and if it is available in North America. The one that Google is pointing at is made in Poland. |
Yes, it is a Polish company, I am based in NL (EU), shipping was fast. I ordered from ampero.eu. There is no US distributor listed so might be better to look for a local alternative. Regarding modbus, there are many safety features (fault checking) are out and otherwise included with the Adafruit libraries. I will try to implement fault checking, specifically if temperature raises at least by 12F/ 6.7C in ~20min when kiln demands near max power output. |
If they don't ship to Canada, I'll ask them to ship it to my relatives in France etc. For the subject of" Fault Checking "; you may be opening a pandora's jar ( or is a box ). In fact I wished the MAXIME SYSTEMS would allow us to shut down or control the " Fault subroutines " in their Max31855/56 chips. The infamous " short circuit " error message in high temperatures when is not the result of ground-loop(s) or actually short circuit is actually a system setting ... * misinterpretation * inside the code MAX31855/56 run. And that cannot be reversed but must be suppressed as whole. So, be careful what dragon you are waking up inside these silicones. What's called eFuses in general or One-Time Programmable (OTP) memory or OTP non-volatile memory (NVM) are quite common in industrial equipment markets. They are made to give wider range of consumer facing manufacturing options. But again, I am sure you knew all this. I will definitely look for your updates as I am building a three zone Production Kiln based on your work. Thank you again for sharing. |

hi . i am exploring esp32 systems as they have built in many of the features that kiln controllers need. i dont know where to post the info on this. can someone who is familiar with github please advise.thank you. Ronald.Sent from my Galaxy

Added support for industrial modbus based industrial thermocouple input modules. This has been confirmed to solve problems associated with MAX31856 at temperatures above 900 C. Has been tested and stable up to 1260 C. Input module used Z-4TC.
