1. INSTALLATION
This section describes the installation of the DeltaSens system. It provides an overview of the
DeltaSens elements, wiring scheme and actions required to start up and configure the DeltaSens
interrogator unit.
1.1. DeltaSens system overview
The central element of the DeltaSens system is the interrogator unit. It acquires the optical signal
from the array of sensors, processes it and provides the user with both analog and digital outputs to
analyze it. To configure the interrogator and setup the measurement parameters, the unit needs to
be connected to a computer with the DeltaSens software installed on it.
1.1.1. DeltaSens operating principle
DeltaSens is a stand-alone system that simultaneously interrogates multiple Fabry-Pérot (FP) sensors
connected through an optical fiber network. By using a single read-out to measure multiple
transducers, DeltaSens provides a cost-effective sensing solution without compromising on
performances. The distance between the sensors and the read-out can vary from centimeters up to
several kilometers.
DeltaSens uses interferometry to measure multiple low-finesse Fabry-Pérot sensors, and therefore
provides a reduced cost per sensor while maintaining high sensitivity and acquisition speed. In
combination with Optics11 fiber-top technology, it can support the measurement of a broad range
of physical parameters such as acceleration, pressure or temperature.
