ABSTRACT:
An engineering unit converter system for converting an analog measurement into an engineering value. An analog measurement of a physical quantity is transformed into a digital value. The digital value is then split into a high order digit and a lower order digit. The high order digit is used as an address to a memory device for fetching a line segment coefficient and a line segment offset coefficient. The lower order digit is multiplied with the line segment coefficient in a multiplier resulting in a product. The product is added to the line segment coefficient offset resulting in a sum whose value is an engineering unit. One embodiment is directed to converting temperature measurements into engineering units via thermocouples. This embodiment includes: thermocouple devices, resistance thermal devices or positive temperature coefficient thermistors, adders, multipliers, and memory devices (readable and writable memory devices).
