Help me calculate the gain parameters of an amplifier

Hi all,



I am having trouble understanding on how to calculate the gain parameters for an amplifier



So, my card has an input range of 0 to 1 V and I need to measure a temperature range of 500 degrees.



Now, is the gain calculated completely linearly???



So, the gain factor is 1/500 = 0.002 So, 0 maps to 0V and 500 degrees maps to 1V...



I am not sure how these amplifiers work as I have never looked at an electronic circuit diagram in my life! Utter newbie when it comes to this stuff.



Any help would be greatly appreciated.



Thanks, D

The question isn't about the amplifier, but rather about the sensor. Do you have a sensor that produces 0V at 0 degrees and 1V at 500 degrees? Most temperature sensors are not inherently linear, but you can also by some where they have been "linearized"...

What temperature sensor are you using?
