    hi guys i have one LM335 temperature sensor and i would like to know how to bias it so it will produce 0-5V when the temperature range is -10C to 55C. cheers

    It won't without supporting op amp circuitry. Plenty of info in the data sheet.

    I'd use a double op amp such as a TL082

    Set the reference voltage on the first stage to get 0V out at your low temperature setpoint, then use the second op amp to provide the gain such that it will put out 5V at the upper temperature setpoint.
