-12V supply power to 0-10V for PCI 6259

[ACHETNA]

Hellow everyone,

I want to acquire a signal from a -12Vdc power supply through my NI PCIe 6259 acquisition card. So, I need to convert it to 0-10V (analog) to make it adaptable to the range of analog inputs on my acquisition card. I have built the circuit below to perform this operation. What do you think of this circuit? Can someone suggest a circuit that is better than mine?

Note: I designed the circuit to convert -13V to 0-10V, not -12V to leave a little margin to avoid damaging the acquisition card in case of exceeding this value.

Thank you very much.
