The LTS device is a "addressable" fast response linear heat detection system, capable of detecting heat over the entire length of the fiber optic sensor cable. The alarm levels are programmed and can be adjusted to meet the unique needs of each part defined in the application. System performance allows: · Timely detection for every meter of fiber in the system. Measure and control the status of an entire system cable in less than 10 seconds. Temperature resolution 1ºC/min. Automatic detection of fiber optic cable breaks. Continuous measurement after rest without interruption of system operation by reading both sides of the fiber. Sensa's Distributed Temperature Measurement System, LTS, The LTS240 solution is based on the time-computed optical reflectance (OTDR) principle. A technology that utilizes the inherent characteristics of changes in light patterns and wavelengths that occur as light travels through an optical fiber. These changes are the result of:
- changes in the density and composition of the medium (Rayleigh dispersion)
- loud vibrations (Brillouin dispersion)
- Molecular vibration (Raman dispersion).
Part of the signal scatters back through the fiber to its origin (backscatter). The condition of the fiber optic cable can be determined based on the return light. The backscattered signal is separated by a directional coupler and then optically filtered and exposed to the detector. At this point, the LTS240 processor, built-in software, and adaptive parameters are used to generate batch configurations that show "events" over fiber.
Tube sensor
Fiber optic cable (SensorTube) is specially designed with low thermal mass to provide fast thermal response to ambient temperature changes. SensorTube is powerful, lightweight and flexible and easy to install. The cable is inserted in a 316Ti stainless steel coating. The SensorTube coating provides a shield that does not require additional protection and can be installed on roofs or other structures, such as fire detection systems or to monitor ambient temperatures. The backscattered signal is separated by a directional coupler and then optically filtered and exposed to the detector. At this point, the LTS240 processor,
