  • Patent number: 7539600
    Abstract: A transmitter including: a sensor, which serves for registering a physical parameter (X) and transducing such into an electrical quantity; a signal pre-processor, which serves for converting the electrical quantity into a raw signal (R); a signal processor, which serves for converting the raw signal (R) into a measurement signal (M); an output stage, which serves for issuing an output signal corresponding to the measurement signal (M); and a monitoring unit, which in operation compares the output signal with an auxiliary signal (H) derived from the raw signal (R) and triggers a safety-directed adjustment of the output signal, when a difference between the output signal and the auxiliary signal (H) exceeds a predetermined limit.
    Type: Grant
    Filed: October 2, 2006
    Date of Patent: May 26, 2009
    Assignee: Endress + Hauser GmbH + Co. KG
