Hi guys,
i have 3 circuits for measurement Voltage, Current and Temperature. I am using the YHDC HV25 for voltage, YHDC HAX25 for current and a PT100 for temperature measurement. I am on the prototyping phase and from the Proteus simulation i see good result on the voltage and current measurement but not at the PT100's. The circuit logic is the same. Anyone has any idea of circuit improvement? I am using AD817 as difference op-amp. Can an instrumentation op-amp give better performance?
Note that i want my outputs to be centered at 2.5V, to drive them to an ADC
1)Voltage 2)Current 3)Temperature
