Fiber optic temperature measurement device for transformer winding in rail transit-INNO

The fiber optic temperature controller for rail transit is a type of temperature controller specially designed for special fields such as subways, locomotives, aviation, kei na so tale; 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 fiber optic temperature sensor as the temperature sensing element. This temperature sensing element is immune to electromagnetic interference and resistant to high voltage (100KV/fiber to ground lead distance of 0.4m). Fluorescent fiber optic temperature measurement completely cuts off the interference transmitted from the temperature measuring element to the temperature controller 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.
