Abstract
A non-optical fiber absorbance probe with light source and photoelectric sensor mounted on the probe features that the monochromatic light source and photoelectric converter are mounted at both ends of a tube made of opaque material, and a liquid inlet and an air outlet are arranged at both ends of the tube to form an optical cavity. When the probe enters the solution to be detected, the solution to be detected enters the light absorption cavity from the liquid inlet, monochromatic light emitted by the light source is absorbed by the solution to be detected in the light absorption cavity and then reaches the photoelectric conversion device through the light, and the photoelectric conversion device converts an optical signal into an electric signal to be output, so that the absorbance or turbidity information of the solution to be detected is obtained; in addition, the utility model consists of a monochromatic light source, a photoelectric converter and a light absorption cavity, and has simple structure, simple and convenient manufacture and low cost.
Description
Affiliated technical field
The utility model designs the online non-optical fiber absorbance probe that a kind of direct immersion detected solution is measured its absorbance or turbidity.
Background technology
The used opticator of spectrophotometer generally is made of light source, beam splitting system, cuvette, optoelectronic sensor.Its volume is bigger, and environment for use is had relatively high expectations, and operates comparatively loaded down with trivial detailsly, can't be applied to require original position, online place.Reach this purpose for addressing this problem common use fibre-optical probe, but fibre-optical probe complex manufacturing technology, cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of light source and optoelectronic induction device to enter the device that detected solution is measured solution absorbency or turbidity, this device has the immersion structure, can be used for original position, on-line monitoring thus, have easy and simple to handle, with low cost, making characteristic of simple simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: photometric light source and these two parts of electrooptical device are installed in a two open ends, in the pipeline that light-proof material is made, make a probe that can enter detected solution, probe leaves inlet and exhausr port, the middle extinction chamber that forms, when probe enters detected solution, detected solution enters the extinction chamber from inlet, after the detected solution of the monochromatic light that is sent by light source in the extinction chamber absorbs, see through light and arrive electrooptical device, electrooptical device is converted to electric signal output with light signal, obtains the absorbance or the turbidity information of detected solution thus.
The beneficial effects of the utility model are that the utility model only needs during mensuration probe is immersed detected solution owing to use the immersion design, does not need lucifuge, and is therefore simple to operate, also can satisfy original position, on-line analysis requirement; The utility model is made up of monochromatic source, electrooptical device and extinction chamber three parts in addition, and is simple in structure, therefore simple for production, with low cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a longitudinal profile of the present utility model structural map.
Fig. 2 is the longitudinal diagram of the embodiment of the non-optical fibre light splitting probe of immersion.
1. light tight shells among the figure, 2. electrooptical device, 3. monochromatic source, 4. extinction chamber, 5. inlet, 6. exhausr port, 7. light source power line, 8. signal wire.
Embodiment
As shown in Figure 1, 2; With light source power line (7) and the signal wire (8) on the probe, connect respectively, to pop one's head in and immerse detected solution, solution enters the extinction chamber from inlet (5), after the detected solution of the monochromatic light that is sent by monochromatic source (3) in the extinction chamber absorbs, see through light and arrive electrooptical device (2), electrooptical device is converted to electric signal with light signal and causes A/D converter spare through signal wire (8) output, obtain the absorbance or the turbidity information of detected solution thus, inlet (5) wherein, exhausr port (6) size is suitable, too greatly then can cause surround lighting to enter the extinction chamber, and influence is measured, the too little solution that then can influence enters extinction chamber speed, certain for guaranteeing light path, must guarantee during use that vent port is under liquid level.
Claims (4)
1. an online non-optical fiber absorbance is popped one's head in, and it is characterized in that: light source and optoelectronic induction device are arranged in light tight shell, and there are inlet and exhausr port in the shell two ends, the middle extinction chamber that is full of by solution that forms.
2. online non-optical fiber absorbance probe according to claim 1 is characterized in that: light source and electrooptical device are installed in the incorporate non-fibre-optical probe of the indoor formation of light-proof material light, and whole probe enters detected solution and measures during work.
3. online non-optical fiber absorbance probe according to claim 1, it is characterized in that: light source is over against the face of accepting of electrooptical device, and both are on same central axis.
4, online non-optical fiber absorbance probe according to claim 1, it is characterized in that: probe is connected with miniature photometer.
