The Yokogawa DTSX1 Fiber Optic Heat Detector protects your equipment against abnormal heat events while being more affordable than other heat detection solutions.
Application
Data centers, both large and small, use busbars or bus ducts for efficient and scalable power distribution. Busbars minimize voltage drops and energy losses over longer distances compared to traditional wiring, making them ideal for delivering consistent power. Their modular design allows for easy scaling as the data center grows, simplifying the addition of new equipment.

Challenges
Busbars simplify power distribution, making it more cost-effective and flexible. They come in various configurations, such as vertical risers or bars within distribution panels. However, a loose bolt or clamp, or a failed welded joint, can increase electrical resistance, causing overheating at that spot. This can further elevate resistance, potentially leading to burnout or even fire.
Overheating in busbars poses serious risks to data center safety. To prevent overheating at any of the bus connections, regular inspections of the busbar and its connections are necessary. However, because busbars are often housed inside plastic or metal bus ducts and covers and are located in hard-to-reach areas, visual inspections can be challenging. Additionally, since busbars carry high currents and voltages, manual inspections pose significant safety hazards. Therefore, alternative monitoring methods are needed to ensure operational safety and efficiency.
Solution
The Yokogawa DTSX1 Fiber Optic Heat Detector is an all-in-one, self-contained fiber optic temperature solution. It protects your equipment and devices against abnormal heat events while being more affordable and convenient than other heat detection solutions.

Fiber-optic cables are installed alongside busbars or on top of bus ducts to detect hotspots, fires, and temperature anomalies. The DTSX also allows individual configuration of alarms and displays to suit specific applications, enabling rapid detection and localization of abnormalities. This helps prevent heat-induced electrical failures and large fire incidents, ensuring continuous operations in data centers and other facilities while protecting critical assets and infrastructure.
Key Benefits
- Cost effective 24/7 heat detection monitoring system with custom individual alarm configuration.
- User friendly with Maintenance-Free fiber optic sensor, reducing downtime.
- Detect problems before major catastrophic events occur.

Chemical
Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
