Thermocouple Transducer circuit

thermocouple circuit

Does anybody give me a circuit which is used to measure Thermocouple voltage and it's output is about 10mV/0C?

You can build an amplifier as per this example:

or

They offer several circuits (samples and data sheets) to operate with thermocouples.

thermocouple transducer

use ad595 from analog device.

Thanks for your reply!
AD595/AD594 is very good but it's so expensive

transducer as thermocouple

use sigma delta converters like as ADS1216 from TI to connect THC to micro,(sensor to digital,directly),you can also use other sigma delta ADCs.

thermocouple can transducer

You can try this appnote. Circuit of Fig. 5 should be just fine for you.

Take a look also at this thread: **broken link removed**.
Usualy, thermocouples (TCs) are not very cost-effective temperature sensors, when you need to measure just one temperature (obviously, TCs have lots of other advantages). They can be quite cost-effective, when you need to measure muiltiple temperatures. TCs can be switched with relays, if you need to sense low temperature. Or with solid-state analog switches (e.g. CD4051), if you're working with high temperatures.
