The proposed work has the aim to investigate a full analog electrical circuitry to convert the wavelength-encoded signal coming from a pair of Fiber Bragg Grating (FBG) sensors into a single monotonic electrical signal. The latter can be used either to be read from a PLC system (or directly by a switch) if a 4-20 mA signal is needed (e.g. [...]

/ Marrazzo, Vincenzo Romano (Naples U. ; INFN, Naples) ; Fienga, Francesco (Naples U. ; INFN, Naples ; CERN) ; Laezza, Dario (Naples U. ; INFN, Naples) ; Riccio, Michele (Naples U.) ; Irace, Andrea (Naples U.) ; Buontempo, Salvatore (INFN, Naples ; CERN) ; Breglio, Giovanni (Naples U. ; CERN)
In this contribution an innovative, full analog, fiber optic sensors (FOS) interrogator is designed which, being fully compatible with the 4-20 mA standard of the Programmable Logic Controller (PLC), enable the integration of the FOS technology in safety framework, such as the Detector Safety System (DSS) of the LHC Experiments. It is composed by a full analog electrical circuitry, capable to directly transduce the signal coming from the arrayed waveguide grating (AWG), into a monotonic electrical current in the range of 4-20mA.

Full Analog Fiber Optic Monitoring System Based on Arrayed Waveguide Grating
/ Marrazzo, Vincenzo Romano (Naples U. ; INFN, Naples) ; Fienga, Francesco (Naples U. ; INFN, Naples ; CERN) ; Laezza, Dario (Naples U. ; INFN, Naples) ; Riccio, Michele (Naples U.) ; Irace, Andrea (Naples U.) ; Buontempo, Salvatore (INFN, Naples ; CERN) ; Breglio, Giovanni (Naples U. ; CERN)
Fiber Optic Sensors (FOS), whose advantages have made them widely used in many applications, are up to now not so diffusely used for the monitoring of industrial processes, mainly due to two aspects: the expensiveness and complexity of the sensors monitoring systems. For these reasons, these sensor systems are usually substituted with low performance but easier to manage sensors, in agreement with industrial monitoring standards. [...]
