The improvement — integrated DAS, DSS and DTS measurements
DTS, DSS and DAS are based on optical time domain reflectometry (OTDR) measurement techniques in which an incident pulse of light is coupled into an optical fiber and backscattered light sampled. As the incident pulse travels along the fibre, at each sampling interval of fiber, a small amount of light is scattered and recaptured by the fibre waveguide in the return direction.
Local variations of the backscatter waveform provide information on the state of the fibre at successive sampling intervals determined by the roundtrip transit time from launching end to point of interest.
Through continuous analyses of the backscattered signal from successive incident pulses, dynamic profiles of temperature, strain, and acoustics are realized as a continuous 2D function of recording time and distance along the fibre.
can be used to detect hot spots and monitor cryogenic processes. Fibre optic cable can be installed to provide coverage on above ground or buried vessels.
A diverse range of applications including leakage and intrusion detection can be implemented for storage tank integrity monitoring.
Our distributed sensing technologies can be readily combined in a single installation delivering leak and intrusion detection as well as temperature monitoring giving complete coverage along a fluid transfer.
Belt conveyor systems
Temperature and/or acoustic monitoring can alert operators to worn components and potential failures. By utilizing distributed fibre optic sensing material transfer systems for up to tens of kilometres can be monitored from a single location.
