What Is Redundancy?

We define redundancy on 2 levels: electronic redundancy and cell redundancy (till oxygen sensor level.)

Electronic redundancy means that the 2 or more measuring/display systems are not linked in any way, except for using the same input (oxygen sensors). This means that the systems are not linked anywhere else, besides where they make contact with the oxygen sensors: so cables shared, no batteries, no displays, no processors…nothing. To make correct electronic redundancy it is important that where the systems join the oxygen sensors, provision must be made that a failure on one system has no influence on the readings of the other system (like using isolating splitters). It is not always possible to achieve this last completely.

Cell redundancy is achieved when there is no link at all between different electronic systems/displays, even including the oxygen sensors (no link means totally no physical connection at all) – example: each sensor having it’s own electronic display system
