But to make that measurement you need an amplifier circuit designed for the thermocouple being used. Linear Technology LTC 1049 Low Power Zero-Drift Operational Amplifier with Internal Capacitors ...

A sudden need for such often results in just buying a either dedicated measurement unit, or some cheap eBay thermocouple board and just rolling with a few hacks. [Jana Marie Hemsing] had a need ...

Because two dissimilar metal wires create different electric potentials over a temperature gradient, a voltage that can be measured is induced in the circuit. Different thermocouple types have ...
