DTSX3000 Distributed Temperature Sensor

What Is Distributed Temperature Sensing?

Distributed temperature sensing (DTS) measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element. Unlike traditional electrical temperature measurement (thermocouples & RTD), the length of the fiber optic cable is the temperature sensor. Distributed temperature sensing can provide thousands of accurate and precise temperature measurements over a long distance. Compared to traditional electrical temperature measurements, distributed temperature sensing represent a cost effective method for obtaining accurate and high resolution temperature measurement.

Introducing Fiber-Optic Temperature Sensor, DTSX

Temperature monitoring throughout large plants without blank areas is difficult due to technical and cost issues and it is hard to comply with corporate HSE policies. DTSX measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element and it is ideal for temperature monitoring over long distances and wide areas. DTSX has been increasingly used in variety of applications such as fire detection, leak detection and preventative maintenance.

 

What Are the Advantages of Using DTS ?

  1. Cost
    When an application requires hundreds or thousands of sensors to be measured, it becomes very expensive to wire each individual sensor back to a data acquisition station. It is much more cost effective and beneficial to acquire accurate and high resolution temperature measurement using fiber optic cable.

  2. Long distance
    It is difficult to measure temperature over a long distance using traditional electrical measurement sensors. Not only can DTS fiber optic cable be deployed over a long distance but it also provides a high resolution profile of the area as well as accurate and precise temperature measurement over that distance.

  3. High electromagnetic noise environment
    DTS is isolated from electromagnetic noise because of its optical characteristics. Unlike traditional electrical measurement sensors (thermocouple & RTD) there is no electrical component within the optical fiber, therefore, it is immune to electromagnetic noise.

What Is DTSX3000 Distributed Temperature Sensor ?

The DTSX3000 can measure up to 50 km long distances. This makes it suitable for measuring the surface temperature distribution of large facilities, such as long-distance power cables, pipelines for transporting liquids and gases, and storage tanks.

Measurement Principle

Operating Principle

Operating principle

Yokogawa DTSX3000 measures temperature and distance over the length of an optical fiber using the Raman scatter principle. A pulse of light (laser pulse) launched into an optical fiber is scattered by fiber glass molecules as it propagates down the fiber and exchanges energy with lattice vibrations. As the light pulse scatters down the fiber optic cable, it produces stokes signal (longer wavelength) and anti-stokes (shorter wavelength) signal, of which both signals shifted from the launch of the light source. The intensity ratio of the two signals components depends on the temperature at the position where the Raman scatter is produced. This temperature can thus be determined by measuring the respective intensities of the stokes and anti-stokes signals. Furthermore, part of the scattered light, known as the backscatter, is guided back towards the light source. The position of the temperature reading can thus be determined by measuring the time taken for the backscatter to return to the source.

 

Raman Scattering

All light interacts with matter! For example, imagine standing in a pitch black garage with no external light source. Inside this garage is a bright red sports car. Needless to say, you cannot see the sports car or the color of the sports car itself. However, when you turn on the lights to the garage, you can immediately see the light source reflecting the bright red color off the car. The light that is bouncing off the red sports car is only bouncing off the "red" spectrum, therefore, your eyes see the sports car as, well, red.

Raman scattering

This phenomena is also true when you shoot a pulse of light (laser pulse) off of a molecule, in this case, the fiber glass molecule in the optical fiber cable. When the light source enters the optical fiber cable, most of the light bounces (backscatter) back unchanged (no change in wavelength). However, a small amount of that light shifted/changed. That shift/change from the light source is called Raman Scatter. Since Raman Scatter is thermally influenced by temperature, the intensity depends on temperature. Distributed temperature sensing is capturing the shift/change from the propagating light pulse and measuring the intensities between the two signal components (stokes and anti-stokes).

 

Types of Scattering Light

Yokogawa's distributed temperature sensors measure temperature distribution using Raman scattering light, which exhibits particularly good temperature sensitivity among the following types of scattering light.

Types of Scattering Light Features Field of Application

  • Caused by fluctuations in the density inside the medium
  • Same frequency components as those of incident light
  • Optical fiber loss distribution
    (OTDR:Optical Time Domain Reflectometer)

Measurement Method

Single-Ended Measurement Method

  • This method launches optical pulses into only one end of the optical fiber for sensing. Easy to install, it is effective when the measuring target is long range.

Single-ended measurement method

 

Double-Ended Measurement Method

  • This method launches optical pulses into both ends of a looped optical fiber for sensing.
  • This method allows for continued measurement even if on place of the fiber optic cable is broken.

Double-ended measurement method

 

Comparison of Measurement Methods

Measurement Method Advantages Disadvantages
Single-Ended Measurement Method
  • Compared to the double-ended measurement, the fiber optic sensor cable can be easily installed.
  • No optical switch is required.
  • Even if the optical fiber is broken, it is possible to continue measurement at points before the broken section.
  • It is impossible to compensate for position-based optical fiber loss fluctuations.
  • The temperature calibration is more complicated than the double-ended measurement.
Double-Ended Measurement Method
  • The optical fiber loss distribution along the optical fiber is automatically canceled out.
  • Yokogawa's method reduces the influence such as darkening.
  • If the optical fiber is broken, the measurement method is automatically switched to the single-ended measurement.
  • The installation of fiber optic sensor cable must be looped.
  • An optical switch is required.
  • The actual maximum distance range for temperatuer measurement is a half that for the single-ended measurement method.

Performance

Representative parameters that indicate the performance of distributed temperature sensors include the spatial resolution and temperature resolution. In spite of the fact that in general, there is a trade-off relationship between these parameters, we have realized high performance based on signal processing technology.

 

Spatial Resolution

  • The spatial resolution is the minimum length that detects changes in temperature (it is also referred to as the response distance).
  • The spatial resolution is defined as the length when a temperature change of 10 to 90 percent of the optical fiber for sensing is detected.
  • The sampling resolution represents the data interval, the definition of which is different from that of the spatial resolution.

Spatial Resolution

 

Temperature Resolution

  • The temperature resolution is defined by the standard deviation (1 σ) of measured values along the fiber optic sensor in a uniform temperature environment (in a thermostat chamber).
  • The temperature resolution is the indicator of variations, which does not indicate temperature accuracy (the use of a reference thermometer in calibration makes it possible to make measurements with a higher temperature accuracy).
  • Raman backscattering light is a very faint signal. By repeating measurements to average measured values, the distributed temperature sensors achieve a higher temperature resolution.

Industries/Applicantions

Power

Yokogawa DTSX3000 can protect the infrastructure of existing power line/cable and reduce cost by monitoring the thermal dynamics of the power transmission and distribution line. By measuring the temperature of the power line, power grid operators can maximize the usable capacity of the power current by avoiding power cable damage and extending the cable life by maintaining optical power current. More importantly, operators can identify hot spots, fire breakout and location of fire along the entire grid. DTSX3000 minimizes the potential power grid network outages and streamlines preventative maintenance process. Because of its immunity to electromagnetic interference, DTSX3000 is ideal for high voltage, high noise environment. DTSX3000 is designed to deploy in the following environments:

  • Underground power cables
  • Subsea power cables
  • Overhead power lines
  • Distribution station
  • Substations

Pipeline

Yokogawa DTSX3000 offers superior pipeline leak detection by using fiber optic solutions that provide a complete temperature profile along the entire length of a pipeline. When a leak occurs anywhere along the pipeline, a localized temperature change is produced at that specific location. The optical fiber cable, due to its close proximity to the pipeline, has adequate thermal contact and can provide accurate temperature readings. By comparing every new temperature profile scan acquired against a reference profile taken under normal conditions, it is possible to detect temperature anomalies which may indicate a possible pipeline failure or external extrusion which might result in or be an actual break. DTSX3000 is designed to deploy in the following applications:

  • Gas pipelines: Ammonia, natural gas, carbon dioxide
  • Liquid pipelines: Crude oil, heated oil, gasoline, PNG, LNG, brine, steam

A leak induced temperature change can be either from a localized cooling or heating. For leaks occurring in pipelines carrying crude oil and other similar products, it is expected that a localized warming will result from a leak as it is often a common practice to transport the crude at a warm temperature to reduce its viscosity.

Leaks in pressurized gas pipelines or those carrying LNG or other cryogenic products, a localized cooling effect will be observed as a result of the Joule Thompson effect, whereby a rapidly expanding gas under pressure lowers the surrounding temperature.

Fire Detection

Early fire detection to critical process and environment is an important component to any safety system. A blazing fire has devastating consequences to important assets, products and most importantly, human lives. Furthermore, the cost of downtime due to fire leads to lost opportunities and costly repairs. Discrete sensor technology often fails due to the surrounding environment conditions such as dust, humidity, heat and corrosion. In addition, it is expensive to maintain a conventional sensor technology due to constant repair. Yokogawa's DTSX3000 is designed to detect fire in critical assets under the most extreme conditions and offers unmatched reliability, performance and cost savings.

DTSX3000 can measure the temperature distribution along an optical fiber with a length of several kilometers are being applied to extraction of unconventional resources. DTSX3000 maximizes oil/gas extraction by providing real time continuous temperature measurement through different injection dynamics. In addition to well optimization, DTSX3000 provides critical data that help monitor and detect wellbore conditions for leaks, water penetration and gas breakthrough. DTSX3000 also provides control capability (measurement of flow, pressure, temperature, valve position, etc.) on top of fiber optic temperature measurement. More importantly, compared to conventional wellbore monitoring technology, DTSX3000 is more robust, cost effective and accurate.
