High Precision Distributed Brillouin Optical Fiber Sensing Monitoring System(HDTSS)


Product introduction


High precision distributed Brillouin optical fiber sensing monitoring system, using differential pulse to Brillouin optical time domain analysis
technology, measurement space division

The highest rate of discrimination is up to 2cmIt is the only one with high spatial resolution and long distance measurement of temperature and strain at the same time.

A force – based optical fiber sensing system. The high precision distributed Brillouin fiber optic sensing monitoring system can simultaneously obtain the temperature and strain of each point of fiber.

Information, with high insulation, anti electromagnetic radiation, corrosion resistance and so on, can realize long distance, high precision temperature and strain distributed measurement.

System composition

  • (1) optical fiber cable. According to the actual situation of the measured objects, the optical cable and the measured object are laid out accordingly, and the temperature of the measured object is carried out through the optical fiber cable.

Real time perception of strain.

  • 2. Sensing host. Completion of laser emission, reception, data acquisition, data analysis and processing toform the temperature of each point of the measured object.
  • Change and position information, and carry out local graphical display, analysis and alarm.
  • 3. Comprehensive monitoring and management platform. All kinds of applications for safety early warning of measured objects are completed.
