Localization along the fiber optic with meter accuracy. Configuration of Zones with associated alarms and relays activation Fiber optic configuration and calibration according to installation parameters Data management, system interfacing Communication interface with third party’ systems (SCADA, ....)

Applications

The DITEST-AIM solution is designed to offer turnkey solutions for pipeline integrity monitoring, ground movement detection and roads & railways infrastructure monitoring.

	Pipeline flow assurance monitoring including detection and localization of leakage or blockage, abnormal temperature change or seabed migration.
	Surveillance of dykes and water embankment for the early detection of seepage and overflow.
	Long distance temperature monitoring for undergroung and subsea transmission power cables and overheadlines

DITEST-LTM - system Components

DITEST Interogator

DITEST-STA Distributed temperature and strain distributed sensing

Performance

Monitoring distance : > 40 km per sensing channel
(2 std channels for each interogator)
Spatial resolution : ~1 m (*)
Temperature resolution : < 0.5°C (*)
Optical loss budget : >10 dB (*)

(*) Temperature resolution, spatial resolution, distance range and acquisition time are inter-related. Please contact us with specific project requirements for more information about performance.

Temperature detection - fiber optic cable

Long range Distributed temperature Optical Fiber Cable
The LTM OFC can accommodate up to 8 fibers. It is a robust cable suitable for direct burial as it integrates rodent protection. The cable includes the optical fibers used for temperature monitoring as well as spare fibers for data communication between the instruments and the control room.

Project Engineering

In each project, Omnisens in collaboration with its solution providers offers project management, specific design specifications with respect to project requirements, complete documentation and implementation plan, installation drawings, training, commissioning and deployment capabilities.

Additional System components

Depending on the project requirements, cabinet, uninterrupted power supplies, batteries, patch panels,
SO-N-2 optical switch modules, data server, can be provided as additional system components.

DRM / DRR / DRRM

Distance range extension (DRR) and Remote Measurement (DRM) modules
The DRR/DRM/DRRM DITEST modules are designed to extend the monitoring capabilities of the DITEST-STA measuring unit, enabling more than 250 km of monitoring distance without compromising on the measurement performances.

The DRR/DRM/DRRM DITEST modules can integrate multiple channel capabilities and are remotely controlled by the DITEST-STA unit via the integration of a dedicated DRM channel to the measuring unit.
