PURPOSE:To make the constitution of an equipment small and light and to attain satisfactory measurement where the influence of an external noise is saved by communicating information between respective signal processing units through each optical coupler and an optical fiber. CONSTITUTION:Measuring equipments 7a to 7c are respectively connected to the respective signal processing units 6a to 6c. A measuring unit is composed by setting a unit composed of the first signal processing unit 6a, first and second optical couplers 5a, 5b and a first measuring equipment 7a to be a first measuring part 1 and similarly composing second and third measuring parts 2, 3 of respective signal processing units 6b, 6c, optical couplers 5c to 5f and measuring equipments 7b to 7c. Then, information on various quantities measured by the respective measuring equipments 7a to 7c are signal-processed by the respective signal processing units 6a to 6c and communicated between the signal processing units through the optical fiber 4. |
