The DTS distributed fiber optic temperature sensor independently developed by FJINNO is currently the new generation of linear fiber optic temperature detectors internationally. It has the advantages of inherent explosion-proof, strong electromagnetic interference resistance, lightning protection, high measurement accuracy, light weight, and small size. In particular, distributed fiber optic temperature sensors are a type of continuous distributed temperature fire detector that can measure temperature at any point along the fiber optic line without measurement blind spots. Fiber optic is both a transmission medium and a sensing element, without the need for additional temperature measurement sensors. It is easy to install, highly reliable, and performs better than traditional linear temperature detectors, making it suitable for chemical tank fire monitoring applications.

Product characteristics of distributed fiber optic temperature measurement system for storage tanks

1. Fiber optic cables are sensors with no fusion points in between, ensuring high reliability: Fiber optic cables themselves are temperature sensors, playing both the role of temperature detectors and signal transmission, integrating “transmission” na “sensing”; Due to the absence of additional sensing components and the lack of fusion points in the middle of the sensing optical cable, it has high reliability.

2. Continuous distributed measurement without measurement blind spots: DTS belongs to continuous distributed measurement, which can obtain the temperature of every point along the sensing optical cable. Currently, the distance interval between adjacent temperature points can reach up to 0.25m, with rich temperature information and no measurement blind spots; And based on continuous temperature analysis, a regional temperature difference alarm method can be implemented.

3. Small post operation and maintenance workload: DTS’ sensing optical cable draws inspiration from outdoor communication optical cable design, and the lifespan of communication optical cables can reach up to 30 years; The core components of the DTS measurement host, such as light sources and spectrometers, are all communication grade devices with a designed lifespan of 100000 hours (over 10 years). The host also has a built-in temperature calibration unit and fault self checking module, ensuring stable and reliable temperature measurement.
