Distributed fiber optic sensing techniques such as Distributed Temperature Sensing DTS are powerful tools for monitoring long linear or other large assets.
Consequently these techniques fit perfectly with specific requirements of fire detection in tunnels large buildings industrial sites and large equipment.
In fire detection applications fiber optic DTS systems are also referred to as a Fiber-Optic Linear Heat Detection FO-LHD systems in contrast to conventional LHD systems that are based on electrical sensing.
Some common fire detection applications are:
Road and railway tunnels
Railway and metro line stations
Cable trays shafts and ducts
Parking lots
Industrial sites such as refineries or steel plants
Hazardous areas
Floating roof tanks
Mines
Conveyor belts
Nuclear power facilities requiring special fiber
In each of these applications distributed fiber optic sensing offers clear benefit in the ability to cover a wide area from a central monitoring point.
There are numerous additional benefits: the passive fiber-optic cable is lightweight small and easy to install.
In addition these cables are unaffected by electromagnetic interference moisture or dust providing clear advantage in comparison to electronic heat and smoke detectors.
This webinar provides guidance on best practices for the selection and installation of cables for distributed DTS in the fire detection domain.
The webinar is presented by FOSA Technology Committee member Julio Toko.
Julio Toko is the Director of Sales - Americas NKT Photonics.
Toko has been with NKT Photonics for 5.5 years.
He holds an engineering degree in Optical Engineering from University of California Davis with emphasis on Fiber-Optic telecommunication and Sensing.
Toko has 10 years of experience in quasi and fully distributed fiber-optic sensing for acoustic seismic temperature and strain monitoring.
