Distributed Temperature Sensing (DTS)

Distributed Temperature Sensing

Distributed Temperature Sensing (DTS) utilizes common optical fibers, which often spanning several kilometers, to function as temperature sensors. linear. This approach provides a spatially high temperature profile with high resolution along the entire length of the sensor cable. DTS is based on the Raman or Brillouin scattering to obtain accurate temperature data. It is launched periodically a laser pulse in the fiber, generating lower energy light that is backscattered and returns to the interrogator, where it is continuously analyzed.

Fiber Optic Temperature Monitoring

The fiber optic monitoring system allows continuous and accurate measurement along its entire length, not just at specific points. Thanks to its coverage capacity of up to 70 km, high resolution and durability, it is ideal for critical applications in industries such as oil, gas, energy and mining. Its safe and passive installation avoids electrical risks, as it does not require active components in the field. In addition, it easily integrates with SCADA systems, PLC or cloud platforms, ensuring efficient and safe monitoring in extreme environments.

Distributed Acoustic Sensing (DAS)

leading-edge technology in distributed acoustic sensing

AP Sensing's 2P² DAS technology provides a true acoustic profile linear along the sensing fiber. Our unique technology enables the measurement and precise location of the amplitude, frequency and phase of the incident sound field. System provides linear output over distance, time and intensity acoustics. This signal quality is achieved with an outstanding signal-to-noise ratio in the range of leading measurement system worldwide. The sensing fiber is suitable for deployment in ATEX zones.

  • Non-intrusive and rugged: Fiber optic acts as a passive sensor, does not require energy in the field, ideal for critical or hazardous environments (ATEX zones).

  • Configuration flexibility:Allows you to adjust the system to prioritize detection of different phenomena (vibrations, impacts, flows, etc.).

  • High signal-to-noise ratio performance: Patented technology that offers clean and reliable measurements even in noisy environments.

  • Low maintenance cost:Once installed, the system requires minimal maintenance compared to traditional electronic sensors.

  • Real-time acoustic monitoring: Detects vibrations, noises and events along the optical fiber in real time.

  • Long distance coverage: Can reach up to 100 km with a single system and without the need for additional equipment distributed in the field.

  • High spatial resolution and sensitivity: detects very small events with precise location along the entire length of the fiber.

  • Use of standard fiber optics: No special cables required; you can take advantage of existing fiber optic infrastructure.
