In July 2018, DEAN Technology's JTW-XOM-DSCDTS-B distributed fiber optic linear heat detector received a type test report from China's National Fire Electronic Product Quality Inspection Center.
The product is designed for distributed temperature monitoring and linear heat detection applications using fiber optic sensing technology.
A distributed fiber optic temperature sensing system uses optical fiber as a continuous temperature-sensing medium, allowing temperature conditions to be monitored along an extended route rather than only at individual sensing points.
For fire detection applications, this approach can help identify abnormal temperature rise and determine the location of the affected section along the sensing cable.
Fiber optic sensing also offers advantages for applications involving long linear assets and environments where conventional electrical sensing technologies may face limitations.
The JTW-XOM-DSCDTS-B model covered by the type test report is associated with a 10 km fiber optic linear heat detection application, as identified in DEAN Technology's original product announcement.
Long-distance linear temperature monitoring can be valuable for infrastructure and industrial environments where continuous thermal monitoring is required across extended areas.
Typical distributed fiber optic temperature monitoring applications can include:
Power cables and cable tunnels
Transportation tunnels
Industrial facilities
Oil storage and petrochemical facilities
Conveyor systems
Other long linear assets requiring temperature or fire monitoring
Type testing is an important part of product verification for fire detection equipment.
The type test report received in July 2018 provides documented evidence relating to the JTW-XOM-DSCDTS-B model at that point in the product's development history.
For engineering companies, system integrators, and project owners evaluating fire detection products, product testing and certification documentation can be important considerations alongside technical specifications, system compatibility, installation requirements, and project-specific fire safety standards.
DEAN Technology continues to develop fiber optic sensing technologies for temperature monitoring and fire detection applications across critical infrastructure and industrial environments.
Distributed temperature sensing technology is now used across applications including power infrastructure, tunnels, industrial facilities, oil and gas environments, and other assets where continuous temperature monitoring and early identification of abnormal heat conditions are required. DSC's current product portfolio continues to include a Distributed Optical Fiber Temperature Sensing System, while its solution portfolio includes DTS applications for power, petrochemical and transportation environments.
