DiTemp XR MMDiTemp-Reading-Unit_medium
The DiTemp® is a unique tool for the evaluation of distributed temperature over several kilometers. 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 mean of a single optical fiber and in just one shot. Its inherent high stability and self-referenced principle of operation allows 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 fiber material. Some photons are scattered backwards and they carry 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 along the optical fiber.

The spectral analysis is combined with measuring the propagation time of the laser pulses along the fiber (radar principle) as the speed of light in the fiber is known. Scanning the entire length of the fiber by short intervals (e. g. 1m) the temperature profile along the fiber is determined. It is important to know that the measured temperature of each interval is the average temperature of that individual fiber section. Due to the high speed of light, fiber lengths of many kilometers can be scanned within fractions of a second.

The system consists of reading unit, sensing cable and accessories. The optical fibers, which are integrated into robust cables, are the temperature sensitive elements and allow the measurement of temperature profiles at arbitrary times, quasi-continuously with a high spatial and temperature resolution along the cable. This is a requirement for the investigation of thermal processes.

The system is used in a wide range of applications that require distributed temperature sensing, such as temperature monitoring of concrete in massive structures, waste disposal sites, on- and off-shore sites in gas and oil industry, hot spots, cold spots and leakage detection of flow lines and reservoirs, building installations, just to name a few.

DiTemp ATTSDiTemp-ATTS_medium
The DiTemp ATTS contains 2 optical fiber sections of approximately 2m length each that can be heated or cooled in a controlled and reproducible way. The system is set to reproduce a temperature rise or drop of the same magnitude as the one expected in the case of an anomaly, e.g. a leakage.

These two sections of fiber are placed at the beginning and at the end of the real sensing cable to test the detection of a simulated event at both extremities and therefore predict the ability to detect real events over the whole length of the sensing cable. The simulated temperature rise or drop events are typically generated every hour. The DiTemp ATTS records the timing of the simulation start and of the received alert from a dedicated zone in a DiTemp Relay Module controlled by the DiView software. If no alert is received after a predefined timeout, the DiTemp ATTS can generate an alert, indicating that the system might be unavailable.

A signal is also available during the heating or cooling cycle, to allow recording by a plant control system. The DiTemp system will detect real leakages also during a simulated test, since the two events take place in different zones. Alerts from the test zone are typically not transmitted to the plant controller and do not initiate any further action.

The system records all timing results, so that a report can be periodically generated to summarize the availability score and the average and maximum reaction times, providing a periodic evaluation of the SIL level (Safety Integrity Level proven by experience).
