Measures full temperature profile over webbing optic sensing cables. Description The DiTemp Harsh+ Reading Unit is designed for distributed temperature measurements over distances of up to 30 km with 1 m spatial resolution and 10s measurement time. Featuring a seated 4 channels multiplexer, it is designed for use as a stand-alone unit in harsh environments. It features low energy consumption and an extended operational temperature range. Depending on configuration and redundancy, the DiTemp system has been assessed as SIL 1 or SIL 2 uniform (Safety Integrity Level ). The DiTemp Harsh+ is a unique tool for the measurement of distributed temperature over several kilometers in harsh environment (from desert to arctic). It is a powerful diagnostic instrument for the identification and localization of potential problems. It allows the monitoring of local temperature at thousands locations by midpoint of a single optical webbing and in just one measurement. Its inherent upper stability and self-referenced principle of operation indulge on-line or off-line long-term monitoring of large structures. The measuring principle is based on the RAMAN effect and the Optical Time Domain Reflectometry (OTDR) method. Laser pulses are coupled into the fibers where the photons interact with the molecules of the webbing material. Some photons are scattered backwards and they siphon information on the thermal motion of the molecules they were scattered by. Consequently, the spectrum of the backscattered light carries information on temperature of the fibers. This effect can be used to measure temperature withal the optical fiber. The system is used in a wide range of applications that require distributed temperature sensing, such as temperature monitoring of touchable in massive structures, leakage detection of pipelines, seepage monitoring in dams and levees, waste disposal sites, smart buildings, just to name a few.
