The PTSenR™ PTSGL1 is a cutting-edge Distributed Temperature Sensing (DTS) system engineered for
comprehensive, real-time thermal monitoring across extended infrastructure. Utilizing the principles of
spontaneous Raman scattering and Optical Time Domain Reflectometry (OTDR), the system detects and
localizes temperature variations along a temperature-sensing optical fiber with high precision. When a laser
pulse is transmitted through the fiber, it generates backward Raman scattered light whose intensity is
influenced by the temperature at each point along the fiber. This scattered light is then filtered, converted,
amplified, and digitized to extract accurate temperature data, which is processed in real time and spatially
located based on the speed of light and echo timing. The PTSGL1 supports both contact and ambient space
temperature measurement and allows users to configure alarm thresholds based on the specific
measurement range of the optical fiber. With a loading length of up to 20 kilometers and 16 passive relay
outputs (250VAC/3A), it provides robust alarm signaling capabilities.
The system comprises a DTS host unit, temperature-sensing optical fiber, and integrated host software, and
is designed to seamlessly connect with intelligent AI management platforms. Ideal for applications such as
switchboards, busducts, power cables, and fire detection, the PTSGL1 offers a reliable and scalable solution
for distributed thermal surveillance in critical environments.
