Sensor data acquisition systems and architectures

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

Abstract:

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 ...
