The DTSX1 is an all-in-one, self-contained fiber optic temperature solution. It protects your equipment and devices against abnormal heat events while being more affordable and convenient than other heat detection solutions.
The DTSX1 measures temperature and detects heat with a fiber optic cable over a wide area quickly and precisely. Alarm displays and sounds are individually configurable to suit your applications, enabling rapid detection, localization, and identification of abnormalities to prevent heat-induced equipment failure or catastrophic fire events.
The DTSX1 is a compact easy-to-deploy solution with integrated I/O and visual alarm panel integral to the design.
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.
This phenomenon is also true when you shoot a pulse of light (laser pulse) off of a molecule, in this case, the fiberglass 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).
The Raman signal is the signal used for evaluation of temperature. It is sufficiently strong and has a unique temperature dependence. Its wavelength is also shifted substantially (about 40/Nm) from the main Rayleigh peak, thereby allowing the dominant Rayleigh and Brillouin peaks to be filtered out.
The Raman signal is comprised of the so-called “Stokes” and “anti-Stokes” bands. The Stokes band at the higher wavelengths (redshifted) is stable with little temperature sensitivity. The anti-Stokes band at the lower wavelengths (blue shifted) exhibits a temperature sensitivity, where the higher the energy within the band, the higher the temperature and vice versa. A ratio of the energy or area within the Anti-Stokes band to that of the Stokes band can be simply related to the temperature of the fiber optic line at the depth where the signal originated.

DTAP3000 Control Visualization Software
The DTSX3000 Control Visualization Software (DTAP3000) is used to control the DTSX3000 and visualize DTS data on a PC. In addition, the software displays measurement data graphs and generate LAS format. DTAP3000 allows a user to perform control, monitoring and analysis from anywhere on Ethernet network.
DTAP3000D Data Conversion Software
The Data Conversion Software option (DTAP3000D) allows the DTSX3000 to generate data files in WITSML format. When the DTSX3000 is configured for WITSML conversion using DTAP3000D, then the DTSX3000 will generate data files in WITSML format.
The latest software that enables you to build a DAQ system without programming. Designed for maximum compatibility with Yokogawa recorders, data loggers, temperature controllers, and power monitors, GA10 can also acquire data via Modbus communications.
