Abstract
The utility model discloses an optical fiber sensor for online measuring petroleum product colors. The utility model is composed of a dual wavelength light source (1), an incidence optical fibre (2), an emergence optical fibre (4), and a photoelectric detector (5). The utility model adopts two luminous diodes (1) as the dual wavelength light source; the incidence optical fibre adopts a Y-typed optical fibre merged dual optical fibre bundle which is suitable for a dual light source; the dual wavelength light source (1) and the incidence optical fibre (2) direct couple. The utility model which has the advantages of simple structure, small size, long service life, low power consumption, and easy control is used for online measuring petroleum product colors.
Description
The present invention relates to a kind of Fibre Optical Sensor that is used for on-line measurement petroleum products color.
Fibre Optical Sensor is subjected to extensive concern as novel sensor, but reaches the few of degree of being practical, and is mainly used in military affairs and space industry, and the industry and the product for civilian use are few.The boat coal freezing point analyzer that present German Benk company produces has used a kind of Fibre Optical Sensor, is used to detect the light transmission of boat coal crystal.
Fibre Optical Sensor involved in the present invention mainly is made up of double-wavelength light source, incident optical, outgoing optical fiber and photoelectric detector.At present, used this type of Fibre Optical Sensor on the 7613 type luminosity alarms that Britain Rotork company produces, its structure is seen accompanying drawing 1.Wherein, form double-wavelength light source by the copped wave dish 3 and the drive motor 4 of tungsten lamp 1, condenser 2, band color filter, incident optical 5 and outgoing optical fiber 7 are the single fiber bundle, and 6 is sample cell, and 8 is detecting device.
The problem of its existence at present is: tungsten lamp is short serviceable life.The diverging light of its generation is through condenser optically focused, and mating plate produces monochromatic light after filtration again.Big, the complex structure of the double-wavelength light source volume of Zu Chenging thus, the tungsten lamp utilization factor is low, and is poor with the optical fiber coupling effect.For normal this double-wavelength light source body that uses must improve tungsten lamp power, further influence the tungsten lamp life-span, and increased the control difficulty.Be difficult to satisfy the long-term requirement of running continuously on the whole.
The purpose of this invention is to provide a kind of simple in structure, volume is little, the life-span is long, low in energy consumption, the manageable Fibre Optical Sensor that is used for on-line measurement petroleum products color.
The characteristics of new Fibre Optical Sensor are: the light emitting diode 1 with two different wave lengths is formed double-wavelength light source.For cooperating two light source incident opticals 2 to adopt two fibre bundles of " Y " type optical fiber or merging, light emitting diode 1 directly is coupled with incident optical 2.
The little monochromaticity of light-emitting diodes pipe volume is good, and with its double-wavelength light source of making, volume simple in structure is little.In conjunction with the lumination of light emitting diode good directionality, can with the direct-coupled characteristics of optical fiber, fundamentally simplified the structure of sensor.Lifetime of LED is long, satisfies the requirement of our long-term operation.Light emitting diode (mW) low in energy consumption, be suitable for current drives and drive current little (mA), can carry out high-precision regulating and controlling by enough integrated circuit, cooperate with detecting device and can realize high-precision closed-loop control adjusting, improve the accuracy of detection and the automatization level that Fibre Optical Sensor uses.
The present invention is further illustrated below in conjunction with drawings and Examples.
New optical fibre sensor structure is seen accompanying drawing 2.We can clearly find out the present invention's improvement structurally from figure, constitute double-wavelength light source 1 by two light emitting diodes, form incident optical 2 with two fibre bundles of " Y " type optical fiber or merging, the direct and optical fiber coupling of light emitting diode.Light is delivered to sample cell 3 by incident optical, is delivering to detecting device 5 by outgoing optical fiber 4.This Fibre Optical Sensor is used as the color optics sensor of the online determination of colority instrument of ZZSY-1 type of our unit development at present, measures the color of decompression side line lubricating oil in industry spot.After adopting Fibre Optical Sensor, make optical system and controller avoid the rugged surroundings of industry spot, guaranteed the operate as normal of instrument.Simultaneously because this optical fibre sensor structure is simple, volume is little, the life-span is long, low in energy consumption, easy to control, simplify instrument structure, reduced instrument design difficulty and power consumption, improved the automatization level of instrument, guarantee the accuracy of measuring, reduced the workload that instrument is safeguarded.At present, this instrument comes into operation and had a surplus in 1 year, the Fibre Optical Sensor reliable operation, and instrument measurement is accurate, has obtained user's favorable comment.
