hello, i am using t type thermocouples for the measurement. am looking for a instrumentation amplifier for the same. i found ad595 is suit for the this type of thermocouples. but the temperature limit for this one is 0-50 degree celsius. for my application the temperature is 20-100 degree celsius. then i found ad849x for j and k type thermocouples..can i use this for t type?,,also is there any special amplifier for t type for the range of 20-100 degree celsius..
T-type and K-type thermocouples require very similar cold-junction compensation voltages. For this reason, I recommend that you use either the AD8495 or AD8497, depending on the ambient temperature…
Yes, you can use a multiplexer for your application. You can check this thread for more information.
I hope it helps!
Because you are using multiple thermocouples, you also have multiple reference junctions. You can transform these junctions into a single junction by using an isothermal block as in the…
