K-BGSA : Multi-point gas sensing cable
K-STRA : Multi-point stress sensing cable

Project Management and Engineering :

Kloé's technical know how and engineering capacity allow it to work in the sensor market with major industrial players as in the transportation of raw materials (oil, gas). Among the services offered are :

• Facility Design
• Design of strings of sensors suitable for on-site detection
• Control / query unit specifications
• Supply tailored cabling solutions
• Blowing/pumping deployment solutions
• On-site connection solutions
• On-site installation support
• Software customized to the site topology

Options :

• Industrial monitoring cabinets (cooling option)
• 1X N optical switches: increase the monitoring capabilities of a single query
• Reinforced cables, adapted to extreme environments
• Supplementary data backup units
• Blowing/pumping deployment units of strings of sensors

The software suite installed on the various monitoring systems primarily provides:

• The operation of optoelectronic material responsible for transmitting and receiving optical signals.


• The retrieval of all information recorded by each sensor (transmitted to the optoelectronic query) at each data update


• The analysis and real-time display of this information


• Warning and alarms when any configured events are detected


• The geolocation (automatic, optional) of events reported on the site representations (2D/3D)


• The archiving of all recorded information.

Ergonomics of human-machine interface was studied in order to have real time access to all important events that may occur on site : the graphics are explicit, and the display, customized to each installation, makes finding the events very accessible.

The technology implemented by Kloé in the area of sensors results from know how originating from the telecom optical industry about thirty years ago. This technology is also subject to numerous international regulations (eg, Telcordia standards), ensuring the performance, robustness and longevity of these systems.

This technology is also subject to numerous international regulations (eg, Telcordia standards), ensuring the performance, robustness and longevity of these systems.

To ensure the reliability of these solutions, Kloé has established a procedure for monitoring the manufacture of each optical sensing cable : each string of sensors is thus characterized several times during its preparation, from the manufacturing of sensors in the heart of the fibers to the on-site supply of coil configuration armored optical cables. Each string is also rigorously calibrated to ensure the response of each sensor on the entire range of operation, according to a procedure that has received the COFRAC accreditation; a specification sheet is established for each optical sensing cable, where all the information recorded by each sensor is reported, from manufacturing to on-site installation. These various controls performed at different stages of sensing cable preparation ensure the continued integrity and proper functioning of each sensor.
