Default Current transformer with high ratio

I'm looking for a current transformer which can take down 40 A rms down to 1-10mA for further transportation in to +-10 V high impedance input. The input is a National Instruments input module. The purpose is to sample the waveform of the current. Most transformers will give me 1 or 5 A out. I'm interested in mA's.

Any clues how to take in an unsulated current signal into a measurement system?

I would suggest doing an internet search for transducers.

Good idea, never thought about that but this doesn't give much.
