T-Laser Distributed Temperature Sensor

For medium to long range (5-30km) industrial monitoring applications where reliability, safety and seamless system integration are essential, the compact, low-power, user friendly T-Laser Distributed Temperature Sensor (DTS) is the ideal solution.
The T-Laser DTS has been designed with safety in mind and has been tested to the industry’s most rigorous standards. The system can be used in many monitoring fields including:

    • Tunnel fire detection
    • Power cable monitoring
    • Oil well (upstream and downstream)
    • Pipe line monitoring and dam leak detection

T-Laser Technology Principle

The Bandeaver T-Laser Distributed Temperature Sensor (DTS) measures the temperature along the fiber using a technique called Optical Time Domain Reflectometry (OTDR). The DTS rapidly sends laser pulses into the fiber optic and measures the reflected light from the optical fiber sensing cable. By analyzing the scattered light at the Raman frequencies the DTS is able to create a distributed temperature measurement along the entire length of the fiber.

T-Laser Interfaces and System Integration

Bandweaver has operated as a system integrator for more than 10 years and has a full range of services from system design through to installation and commissioning.
We have extensive experience in designing our systems to interface with standard industrial formats and specific customer request.

Bandweaver has designed specific customer user interfaces to consolidate, manage and visualize both DTS data (including 3rd party DTS systems) and integrating other data feeds. Equally, Bandweaver is also comfortable exporting data into 3rd party systems and networks. Examples of some of the interfaces Bandweaver has worked with include:

  • SCADA
  • Modbus / DNP3
  • WITSML
  • Electrical relay outputs
  • OPC / IEC61850 / Generic Object Oriented Substation Events
