Sensor data acquisition systems and architectures

M.D. Todd,    University of California San Diego, USA


This chapter describes key topics in the design and operation of conventional data acquisition systems used for structural health monitoring. These systems are discussed by four sub-system modules: (1) the sensor module, which consists of the physical element(s) that interact with the system-under-test to sense the physical process(es) and convert that information into a detectable signal form (e.g., an electrical voltage); (2) the signal conditioning module, which may have any number of functions, which could be further subdivided into analog functions (voltage amplification, some types of filtering, and possibly telemetry) and ...
