can anyone suggest an amplifier for a pt100 thermocouple 3 leadshttp://www.virtualvillage.com/thermocouple-temperature-probe-pt100-003820-034.html

also please explain how to wire one to an arduino

general advice much appreciated

I am a complete beginner (electronics, arduino, programing)



So a bigger noob asks this question:

Where are the leads for the PT100 and the arduino input pins?

Thank you.


The signal named ADC is what wires to a arduino analog input pin as well as the ground pin and the +5vdc. The PT is the top right component in that drawing. But without knowing the values for the R3 and R4 resistors it may be hard to get the circuit working correctly.
