Multiple sensor system

An extension unit applied to a multiple displacement sensor system comprising an amp unit row in which one or more amp units constituting an amp isolated type of displacement sensor are adjacently provided, and a transmission line connected to each amp unit constituting the amp unit row and transmitting measurement data generated in each amp unit in one direction,

• connected to and provide adjacent to the amp unit positioned at an end on the downstream of the transmission line in the amp unit row similar to the amp unit, and
• comprising a storing part for storing one or more process programs in which measurement algorithm is sectionalized together with their identification information and execution addresses by measurement stage in which execution sequence is predetermined,
• an input part for inputting the identification information and the execution sequence of the process programs to be executed by measurement stage,
• a table creating part for creating a measurement process table comprising the execution sequence input by the input part and the execution addresses read by the storing part, and
• a measurement stage based program executing part for reading and executing one or more process programs by measurement stage based on the measurement process table.
