Overheating and smoldering fires in cable trays and service tunnels<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cable trays and service tunnels in industrial plants, data centers, and infrastructure facilities represent a significant fire risk. Overheated cables, loose connections, or insulation damage often cause gradual temperature increases that point\u2011type detectors fail to detect in time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The <a href=\"https:\/\/www.yokogawa.com\/eu\/solutions\/products-and-services\/measurement\/field-instruments-products\/fiber-optic-sensor\/?utm_source=linkedin&amp;utm_medium=social&amp;utm_campaign&amp;utm_content=ap_2d6vfdwaxe\">DTSX\u2122<\/a>1 addresses these challenges by offering:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>continuous temperature measurement <strong>along the entire fiber optic cable<\/strong><\/li>\n\n\n\n<li><strong>meter\u2011by\u2011meter hotspot localization<\/strong><\/li>\n\n\n\n<li>reliable fire detection over <strong>distances of up to 16 km per channel<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This allows critical temperature developments to be identified at a very early stage &#8211; well before a fire breaks out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Fire risks in tunnels, underground parking garages, and transport infrastructure<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Road tunnels, rail tunnels, metro systems, and parking garages subject fire detection systems to extreme conditions such as dirt, humidity, vibration, and long monitoring distances. Traditional sensors often struggle under these conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The<a href=\"https:\/\/www.yokogawa.com\/eu\/solutions\/products-and-services\/measurement\/field-instruments-products\/fiber-optic-sensor\/?utm_source=linkedin&amp;utm_medium=social&amp;utm_campaign&amp;utm_content=ap_2d6vfdwaxe\"> DTSX\u21221<\/a> is specifically designed for such environments:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>certified according to <strong>DIN EN 54\u201122<\/strong> and approved by VdS<\/li>\n\n\n\n<li>robust fiber optic sensing cables with <strong>no electrical components in the field<\/strong><\/li>\n\n\n\n<li><strong>redundant system design options<\/strong> to ensure continued monitoring even if a cable is damaged<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As a result, the DTSX\u21221 is ideally suited for <strong>mission\u2011critical fire protection applications<\/strong> where maximum reliability is essential.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Early detection of thermal abnormalities in conveyor systems and industrial processes<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Conveyor belts, bulk material handling systems, and industrial production lines present a high risk of heat\u2011related incidents. Blocked rollers, bearing failures, or hot transported materials can remain undetected for long periods and often lead to fires or unplanned downtime.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>With the<a href=\"https:\/\/www.yokogawa.com\/eu\/solutions\/products-and-services\/measurement\/field-instruments-products\/fiber-optic-sensor\/?utm_source=linkedin&amp;utm_medium=social&amp;utm_campaign&amp;utm_content=ap_2d6vfdwaxe\"> DTSX\u21221<\/a>, operators benefit from:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>continuous temperature monitoring<\/strong> along the entire conveyor route<\/li>\n\n\n\n<li>freely configurable alarm zones and temperature thresholds<\/li>\n\n\n\n<li>easy integration into fire alarm and control systems via <strong>standard interfaces such as Modbus TCP\/IP<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This makes the DTSX\u21221 not only a fire detection solution, but also a powerful tool for <strong>preventive maintenance and operational safety<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"510\" height=\"287\" src=\"https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTSX-Blog-31.jpg\" alt=\"\" class=\"wp-image-12500\" srcset=\"https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTSX-Blog-31.jpg 510w, https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTSX-Blog-31-300x169.jpg 300w, https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTSX-Blog-31-356x200.jpg 356w\" sizes=\"(max-width: 510px) 100vw, 510px\" \/><\/figure>\n\n\n\n<h2 id=\"h-technology-and-key-benefits-at-a-glance\" class=\"wp-block-heading\"><strong>Technology and Key Benefits at a Glance<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.yokogawa.com\/eu\/solutions\/products-and-services\/measurement\/field-instruments-products\/fiber-optic-sensor\/?utm_source=linkedin&amp;utm_medium=social&amp;utm_campaign&amp;utm_content=ap_2d6vfdwaxe\">DTSX\u21221 <\/a>uses <strong>fiber optic Distributed Temperature Sensing (DTS)<\/strong> technology, where a single fiber optic cable acts as a continuous temperature sensor along its entire length.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key advantages include:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>resettable linear heat detector compliant with <strong>DIN EN 54\u201122<\/strong><\/li>\n\n\n\n<li><strong>VdS\u2011approved<\/strong> (e.g., classes A1N, A2N, BN, CN)<\/li>\n\n\n\n<li>precise localization of temperature events with high spatial resolution<\/li>\n\n\n\n<li>long monitoring distances with minimal maintenance requirements<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This makes the DTSX\u21221 particularly suitable for <strong>large\u2011scale and safety\u2011critical applications<\/strong> where conventional heat detectors are insufficient.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"907\" height=\"300\" src=\"https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTS-Blog3.jpg\" alt=\"\" class=\"wp-image-12507\" srcset=\"https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTS-Blog3.jpg 907w, https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTS-Blog3-300x99.jpg 300w, https:\/\/www.yokogawa.com\/eu\/blog\/app\/uploads\/sites\/8\/2026\/06\/DTS-Blog3-768x254.jpg 768w\" sizes=\"(max-width: 907px) 100vw, 907px\" \/><\/figure>\n\n\n\n<h2 id=\"h-conclusion-greater-safety-through-linear-heat-detection\" class=\"wp-block-heading\"><strong>Conclusion: Greater Safety Through Linear Heat Detection<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Whether in tunnels, cable trays, or industrial conveyor systems, the <strong>DTSX\u21221 from Yokogawa<\/strong> provides a <strong>reliable, certified, and proven solution<\/strong> for demanding fire protection tasks.
