Patent number: 8976498Abstract: A field device for determining and/or monitoring a physical or chemical, process variable in automation technology. The field device comprises: at least one microcontroller; a supply unit of limited capacity as primary voltage supply; and a detection circuit, which signals the microcontroller of a failure of the supply unit so early by means of a detection signal that sufficient time is available to take suitable safety measures, in order to avoid loss of data.
