The tail end length of ceramic pipe is 2mm.
The length of plastic optical fiber is 2～9m.
Compared with prior art, the beneficial effect of the utility model is, the fluorescent optical fiber temperature sensor that is provided can the fast and accurate measurement object surface temperature; And simple in structure, cost is low, in the work progress; Only need with heat-conducting glue that sensor ceramic head and testee is bonding, easily simple.
Description of drawings
Fig. 1 is the structural representation of a kind of point type fluorescent optical fiber temperature sensor of providing of the utility model embodiment;
Wherein, 1, FC/PC fiber connector; 2, plastic optical fiber; 3, ceramic pipe; 4, glue; 5, fluorescent powder.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model technical scheme is further described.
Embodiment 1
Referring to accompanying drawing 1, it is the structural representation of a kind of point type fluorescent optical fiber temperature sensor of providing of present embodiment, and the structure of this fibre optic temperature sensor is: FC/PC fiber connector 1, plastic optical fiber 2 and ceramic pipe 3 connect successively mutually; The length of plastic optical fiber can be 2 to 9 meters and does not wait, and an end is connected with the FC/PC fiber connector, and the other end is through glue ceramic pipe 3; Ceramic pipe length is 23mm, and external diameter 5mm pours into fluorescent powder 5 in the ceramic pipe, and fluorescent powder is compressed close, vacates 2mm at the ceramic pipe tail end, does not irritate fluorescent powder, pours into glue 4, ceramic pipe is put the glue sealing, and be heating and curing; The external diameter of plastic optical fiber and the internal diameter of ceramic pipe are basic identical, and plastic optical fiber tip length 5mm section is inserted in the ceramic pipe behind the coating glue, and glue is adhesively fixed them.
When the FC/PC connector through sensor one end when it sends a branch of light pulse; Light pulse will transfer to end along plastic optical fiber, and shine on the fluorescent powder, and fluorescent powder absorbs this pulsed light; And can inspire fluorescence; Fluorescence can pass through plastic optical fiber end coupled into optical fibres once more, and passes through this Optical Fiber Transmission to the FC/PC connector, then from the connector outgoing; Because fluorescent powder environment temperature of living in is different, the decay life-span of fluorescence is also different, so, through surveying the decay life-span of fluorescence, just can learn fluorescent powder environment temperature of living in, can know object surface temperature then.
The utility model provides a kind of fibre optic temperature sensor that utilizes fluorescence decay life-span thermometric, and it is simple in structure, and is with low cost, easy to use, and can measure the surface temperature of testee quickly and accurately, has practical value.
