Abstract
A process control device is disclosed. The process control device comprises a measuring circuit ( ) and a power regulator circuit ( ). The measuring circuit ( ) is coupled to the power regulator ( ), and produces a control signal indicative of a measured value. The power regulator circuit ( ) redirects a portion of the available power from the power regulator circuit ( ) in proportion to the control signal produced by the measuring circuit ( ) such that it does not limit available power to the measuring circuit ( ). The process control device also may comprise a power control circuit ( ) coupled to the measuring circuit ( ). The power control circuit ( ) redirects an amount of available power from the power regulator circuit ( ) in proportion to the control signal. The process control device also comprisies two or more conductors ( ) that are in electrical communication with the power regulator circuit ( ) and the power control circuit ( ). These conductors ( ) deliver the available power to the power regulator circuit ( ) and the power control circuit ( ), as well as receiving a first electric signal from the power regulator circuit ( ) and a second electric signal from the power control circuit (
