SEN0264 maximum temperature product vs specification
FTJ.Vonk 2024-10-18 16:54:13 234 Views3 Replies In the specification of the SEN0264 product the temperature measuring range is: -70 ~ 270 C.
At the bottom of this page:
https://wiki.dfrobot.com/TS01_IR_Thermal_Sensor_(4-20mA)_SKU_SEN0264#target_7
there is a link to the specification sheet:
https://github.com/Frances9/SEN0264/raw/master/%5BSEN0264-TS01%5D-20180925-V1.0.pdf
The specification sheet mentions a temperature measuring range of: -70 ~380 C.
At both places the range of the output current is 4 - 20 mA.
So, the range has been cut, the highest temperature is reduced from 380 to 270 C.
QUESTION 1: why is the upper limit for the temperature all of a sudden much lower ?
QUESTION 2: what can I do to measure temperature all the way till 380 C ?
It’s possible that the product has undergone revisions or updates that reduced the maximum temperature range to improve accuracy, safety, or reliability. Manufacturers sometimes adjust product capabilities for general users to ensure better performance within certain limits. Alternatively, it could be a documentation error, where one source wasn't updated. To measure temperatures up to 380°C, you could look for alternative versions or check if a specific configuration of the SEN0264 allows for the higher range, or even explore sensors designed specifically for high-temperature environments.

Reaction.Last Thank you for your answer and suggestions. I assume you are answering on behalf of DFRobot.
If the enclosed specification sheet of SEN0264-TS01 version 1 is obsolete, then please send me the correct datasheet. It would be very helpful to know what has been changed in order to map a smaller temperature range to the same current range.
If the temperature exceeds 270C is the current then clipped at 20 mA, or does it still increase till 380 C has been reached ?
Thank you for your help.
