Inductive Telemetric Measurement Systems for Remote Sensing
D. Marioli, Emilio Sardini, Mauro Serpelloni · InTech eBooks · 2010
Inductive telemetric systems offer solutions to specific applications where the measurement data should be acquired in environments that are incompatible with the active electronics or are inaccessible. They also work without batteries, consequently reducing the problem of environmental impact. The general architecture of an inductive telemetric system, the measurement techniques, commonly used, were presented, along with the description of developed telemetric systems applied in harsh or hermetic environments. Two examples of passive inductive telemetric systems were reported, the first one for humidity measurements which presents a distance interval of about 30 mm and the possibility to compensate the distance variation. The second one can measure high temperatures with a maximum limit of about 350 °C, guaranteeing the inviolability of the harsh environment.
