  • Page 9: General

    General The DT302 has a built-in temperature sensor to compensate for temperature variations. At the factory, each transmitter is submitted to a temperature cycle process, and the characteristics under different pressures and temperatures are recorded in the transmitter memory. At the field, this feature minimizes the temperature variation effect.

    CONFIGURATION One of the many advantages of Fieldbus is that device configuration is independent of the configurator. The DT302 may be configured by a third party terminal or operator console. Any particular configurator is therefore not addressed here. The DT302 contain one input transducer block, one resource, one display transducer block and functions blocks.
