A sensor apparatus includes a plurality of sensing elements within an integrated sensing package. Each sensing element is directed at sensing the same parameter. Each sensing elements operates under a principle that is unique from the others thereby providing individual parameter measurements that are substantially immune from common mode effects due to generic influences upon the sensing elements and may exhibit different failure modes. Sensing element signals are acquired, validated and fused within the integrated sensing package, preferably with micro-controller based circuitry. A single output from the sensor apparatus is communicated directly to a programmable logic controller, microprocessor or over a network or other bus.
