How a sensor supply circuit should be?
The sensor requires a power supply with an output voltage anywhere between   \$\pm\$ 6 volts and  \$\pm\$ 15 volts, and the sensor will draw 10 milliamperes from the supply if it's a \$\pm\$ 6 volt supply. The data sheet doesn't specify the current needed by the sensor at other input voltage levels.

The type of power supply will probably depend on what the supply input needs to be, (AC mains, DC supply, battery, etc.) and if you can define that (edit your question instead of leaving a comment) we'll be able to get you closer to your goal.

You shouldn't have to current limit the supply outputs, and if you need to do something on the supply input that'll depend on what kind of supply it is. 

Here's a link to a nice little dual supply, and here's the first page:
