نحوه استفاده از سیستم اندازه گیری دمای فیبر نوری توزیع شده برای نظارت بر دمای مخازن ذخیره روغن

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, مقاومت تداخل الکترومغناطیسی قوی, حفاظت در برابر صاعقه, دقت اندازه گیری بالا, وزن سبک, و سایز کوچک. 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 حسگرها, playing both the role of temperature detectors and signal transmission, integrating “انتقال” و “حس کردن”; Due to the absence of additional sensing components and the lack of fusion points in the middle of the sensing optical cable, قابلیت اطمینان بالایی دارد.

2. اندازه گیری مستمر توزیع شده بدون اندازه گیری نقاط کور: DTS belongs to continuous distributed measurement, which can obtain the temperature of every point along the sensing optical cable. در حال حاضر, 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 سال; 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 ساعت (تمام 10 سال). The host also has a built-in temperature calibration unit and fault self checking module, ensuring stable and reliable temperature measurement.
