Abstract:
A field device (20, 200) includes diagnostic circuitry (36) adapted to measure a characteristic related to a process control and measurement system (10). The measured characteristic is used to provide a diagnostic output indicative of a condition of the process control and measurement system (10). The measured characteristic can be provided to a diagnostic module that operates upon the measured characteristic to predict, or otherwise model, a condition of the process control and measurement system (10).
Abstract:
A process transmitter (100) suitable for coupling to a process loop (120) is disclosed. The process transmitter (100) includes a power regulator (210) adapted to receive a power signal on the process loop (120) and to provide a first signal (215) having a first voltage. Digital components (220) of the process transmitter (100) are electrically coupled to the power regulator (210) to receive power from the first signal (215). A step-up converter (230) is electrically coupled to the power regulator (210) and receives the first signal (215). The step-up converter (230) outputs a second signal (235) having a second voltage larger than the first voltage. Analog components (240) of the process transmitter (100) are electrically coupled to the step-up converter (230) to receive power from the second signal (235).
