The fiber optic temperature sensor can be used for high voltage, strong magnetic field, flammable and explosive temperature measurement occasions. For example: high temperature hot spot temperature measurement of electrical equipment such as rail transit dry type transformer, special environment temperature measurement of photovoltaic equipment, high voltage contact of switch cabinet, etc. .
The optical fiber temperature transmitter can be powered by DC24V or AC220V, and the number of channels for temperature measurement can reach up to 16. It can provide standard RS485 communication interface or 4-20mA analog current output, and can transmit temperature information far to the background. Specially for the electric switchgear real-time on-line temperature detection development, the installation nimbly, the channel configuration nimbly may provide up to 4 dry contact point output according to the user's demand, may connect the skyray standard liquid crystal display instrument.
