2 140,000 m range Recording of thousands of measurement points, even at distant locations. The safety requirements for industrial assets, such as pipelines, oil and gas tanks, large chemical production plants and infrastructure, are steadily increasing. With the LIOS PRE.VENT DTS (Distributed Temperature Sensing) system, the operator can monitor thousands of temperature measurement points of the asset, optimise operation and detect hazardous situations in the early stages. The temperature is measured with a fibre optic sensor cable connected to the DTS unit.

Induction furnaces, blast furnaces The LIOS PRE.VENT temperature monitoring system, with its fibre optic sensor, can be used in areas in which conventional temperature sensors (e.g. thermocouples such as Pt100) cannot be used due to the specific circumstances (i.e. electromagnetic fields), new areas of applications are opened up. One example is temperature measurement in induction furnaces and blast furnaces. Here, the system is used to measure the thickness of the insulation layers for process optimisation in the furnace. The precise pinpointing of hotspots suggests potential locations of damage in a very early stage. The furnace can therefore be operated much more safely and cost efficient. This allows maintenance and repair work to be controlled and planned. Downtimes are reduced, while the efficiency of the system is significantly increased.

Pipelines and storage tanks LIOS PRE.VENT is a system that allows you to monitor a distance up to 140 km with only one measuring device, with high precision and no gaps.

Potential material and environmental damage can thus be reduced, while the safety, operational life and efficiency of the pipelines and tanks are significantly increased.

4 Pipelines and storage tanks LIOS PRE.VENT is a system that allows you to monitor a distance up to 140 km with only one measuring device, with high precision and no gaps. Leakage (due to temperature differences) as well as sabotage and earth movements (due to mechanical change transferred to the fibre) can be pinpointed to the meter in a very short amount of time. Potential material and environmental damage can thus be reduced, while the safety, operational life and efficiency of the pipelines and tanks are significantly increased. The measured values are updated (depending on the desired temperature resolution) after just a few seconds. You therefore obtain a highly precise temperature profile of the area. System monitoring and process optimisation The LIOS PRE.VENT DTS is a linear temperature sensor that enables you to record and analyse thousands of measuring points simultaneously, send alarms if necessary or control your system. With special low or high-temperature fibres (depending on the application), the entire area of your asset is monitored by fibre optic sensor cables. The highly flexible installation of the sensor cable can be adapted to different geometric shapes, and can therefore be implemented optimally for the specific circumstances on site. The coating of the glass fibre is tailored to the specific requirements on site. A thin-walled but very sturdy stainless steel tube offers suitable protection for industrial applications. Special coatings such as silicon or alloys are also possible by customer request. The DTS unit can record an entire measuring section of several kilometres with a sampling interval of just a few centimetres. Application example for reactor surface monitoring: High-temperature sensor cable in a stainless steel tube and high-temperature magnetic holders laid in a meandering shape.

5 THE standard for highly reliable DTS systems Great reliability is an important quality of OFDR technology as only used by LIOS. In contrast to OTDR technology, there are no integrated pulsed lasers with constant load changes and high peak powers. LIOS OFDR DTS uses the laser in continuous operation, thereby preventing fatigue and wear of the laser and other optical components. Due to this high availability, LIOS DTS systems are especially qualified for use in safetyrelevant industrial applications and infrastructures. Key features of the Raman OFDR DTS measuring technology from LIOS Technology GmbH: High availability with industrial design. MTBF over 30 years in accordance with Telecordia standard GR-468. Signal processing based on patented OFDR technology The fundamental advantages of OFDR technology are based on the continuous operation of the laser with a constant wavelength and constant energy. Pulsed operation was consciously ruled out. Due to the narrow-band detection of the optical backscatter signal, the signal-to-noise ratio is significantly better than that with a measuring device based on OTDR technology. Superior hotspot detection along the entire length of the sensor cable Measurements have consistent local resolution, even at points that are far away. OFDR technology offers consistent local resolution along the entire fibre. This guarantees a temperature measurement that can be clearly located. CONVEYOR BELTS OIL REFINING In contrast to OTDR technology, there are no dispersion effects in the glass fibre causing declining local resolutions. Flexible connection options and direct communication with SCADA and process control systems Support of standardised industrial protocols (e.g. DNP3, MODBUS, IEC , IEC 61850, XML) for connection to the control system of the system operator. Up to 16 internal fibre-optic measurement channels - Integrated fibre switch, up to 16 independent measurement channels are possible per device. - Temperature resolution < 1 C - laser class 1M (DIN EN :2007) 100% maintenance-free due to passive cooling of the housing. No moving parts present, such as ventilators. International authorisations and certificates as well as accreditations Due to the high requirements placed on safety-relevant measuring technology, LIOS provides a thoroughly tested system. This complies with international requirements and quality standards. Our partners include independent testing organisations (e.g. TÜV Rheinland, VdS, EXAM, UL). Over 4,000 DTS systems are installed worldwide LIOS Technology is by far the world market leader for linear temperature sensing technology. Our devices are tested individually and shipped to customers with individual FAT documents. Very thorough SATs are done on site after installation, in order to turn over a flawlessly functioning product to the customer.
