hi

if some one have any idea about how i can make a thermocouple amplifier with temperature compensation that required easy calibration procedure

looking forwards to experts here

AD594 ad595 from ADI and some other parts from www.linear.com may help you.(see their AN)

thermocouple temperature compensation

that is true but it is depend on your thermocouple type
if you are using j or k or T type you can use AD594 or Ad595 but you must know that the maximum temprature which you can measure with this ics is about 1250c.

ad594 calibration

a more professional approach is to use sigma delta ADC(16bit or higher) and use a microcontroller to calibrate and linearize ADC output in digital domain.

Such these ADC are available from TI(BurrBrown,ADI,Linear,...),for example AD7715,AD7714,ADS1216,ADS1241.

All termocouple types with any temp range can be defined in firmware.

search on google for more data.

u can use the INA 101 it is instrument Amplifire i worked on it .......... i got good results

Maxim makes MAX6675, which is a complete Type-T thermocouple front end with cold junction compensation, amplifier and ADC.
