I'm using a MAX31855 with the adafruit library to acquire a thermocouple temperature but I wonder how many (reasonably) request is possible to make per second ?
only for thermocouple reading ?
only for internal cold junction reading ?
both for thermocouple and internal reading ?
And what determine that number of request per second ?
I didn't find any information even in datasheet ! (might be bad reading)
Any information appreciated.
I did some googling and found this datasheet which you may or may not have read before. I found a table that listed the temperature conversion time at 70-100 milliseconds. It also lists that time as (Thermocouple, cold junction, fault detection) which I’m guessing means each has a conversion time that falls into the 70 to 100 millisecond range.
Yes, it is at the top of the page 4 of that document !
I need to pay more attention and get myself some good glasses indded !
Thanks a lot.
