Simulate PT-1000 temperature sensor

Hi,

Can anybody give me an idea how to simulate a PT-1000 sensor?

A PT-1000 sensor is a resistive temperature sensor, with 1000 ohms at 0 degrees Celsius.

I want my arduino to output a "resistive output" and don't realize how. I guess I should use a PWM output, but what hardware is needed?

Thanks for any tips and ideas...

You can't do that directly, you need a digitally controlled pot.
