#71263 - RE: thank you
Responding to: ???'s previous message
Dear Raghu:
Thank you very much.


Just ensure that you use a sensor that has a very fast response - these are sensors that abosrb very little heat from the object being sensed to make the measurement.


You are absolutely right, this is extremely important. For example LM35 has a response time of 3 minutes! in still air and even in best conditions(stirred oil bath) TO-92 package has a response time of about 10 Seconds and TO-46 package has response time of about 4 seconds ; using this part with sampling rate of even 1 Hz is a joke! :-)


A word of caution on using multiple sensors: You are entering a domain of thermal profiling and if your idea is to reach a SINGLE temperature for logging - you ARE increasing your computational load !!

You are absolutely right.

thank you very much indeed
