I have 5 DS18B20 sensors running all accurate with no problems.

Thanks for your help everyone

They should be okay, can even work with 3.3 Volt from the pi. For the Guy with 10 or more OneWire-Sensors, first try for me is to go down with the PullUp-Resistor, this should replaced with 2k2 or even 1k Ohms.
