أجهزة استشعار درجة حرارة الألياف الضوئية INNO ,أنظمة مراقبة درجة الحرارة.
The fiber optic temperature controller for rail transit is a type of temperature controller specially designed for special fields such as subways, locomotives, الطيران, إلخ; Due to the impact current interference of traction current on track circuits in these fields, as well as the interference of unbalanced current and poor traction return current, temperature controllers are required to have good electromagnetic compatibility in these aspects.
Our independently developed fluorescent fiber optic temperature sensor is a new principle temperature measurement device. Its principle is that the fiber optic module emits laser, which is transmitted to the end of the temperature sensing probe through the fiber optic. The rare earth material at the end receives light, and the reflected light is transmitted back to the fiber optic module. The fiber optic module decomposes the temperature information in the reflected light.
This product uses our company’s independently developed fluorescent مستشعر درجة حرارة الألياف الضوئية كعنصر استشعار درجة الحرارة. عنصر استشعار درجة الحرارة هذا محصن ضد التداخل الكهرومغناطيسي ومقاوم للجهد العالي (100KV/الألياف إلى الأرض مسافة الرصاص 0.4 متر). Fluorescent fiber optic temperature measurement completely cuts off the interference transmitted from the temperature measuring element to the تحكم في درجة الحرارة from the temperature measurement source. The overall anti-interference ability of the temperature controller is extremely strong, the output contact capacity is large, the functions are complete, the LCD interface is illustrated, the setting is simple, and easy to operate, with reliable EMC and EMI performance.

Characteristics of temperature controllers for rail transit:
1. The protection level is IP54.
2. The output contact capacity is large.
3. Fiber optic temperature measurement is the first in China and at the international leading level.
4. The temperature controller uses the ARM architecture CPU, which has strong data processing capabilities and stable system performance.
5. Large LCD screen with digital and Chinese display.
The design concept of the circuit board for button operation and LED signal indication display of the temperature controller is modular design, with strong and weak electrical separation to avoid spatial crosstalk.
7. The temperature controller contains a clock chip and an external FLASH, which can be customized for high-capacity, time marked historical data storage
