Abstract
The utility model relates to a gas concentration sensor light absorbing pool, which belongs to the field of gas concentration testing device used sensor. The light absorbing pool comprises a glass tube main body (1), an inlet (2), an outlet (3) and a light reflection layer (4). The glass tube main body is helical, one end of which is the inlet (2), while the other end of which is the outlet (3); the light reflection layer (4) is plated on outside of the glass tube main body (1). By adopting helical glass tube, the utility model prolongs optical path, reduces the light pool volume largely, can use long wavelength light source with the service life more than 50000 hours and can work continuously for a long time stably and reliably; the utility model also achieves the advantages of small volume, simple structure, low using cost, simple maintenance, accurate detection data, easily mastered usage and convenient in light pool washing.
Description
Technical field
Gas concentration sensor absorbing light pond belongs to the gas concentration detection apparatus sensor field, specifically is gas concentration sensor gas absorption parts.
Background technology
The existing gas concentration sensor that is used for detected gas concentration is absorbing hour use short wavelength's light source of optical path length, and this light source life is short, has caused the use cost of existing gas concentration sensor higher, safeguards complicated.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of optical length is provided, can use the long-life light source, the gas concentration sensor absorbing light pond that cost is low.
The technical scheme that its technical matters that solves the utility model adopts is: this gas concentration sensor absorbing light pond, it is characterized in that: comprise glass tube main body, import, outlet, reflection layer, the glass tube main body is a spiral fashion, one end is import, the other end is outlet, and the glass tube main body is coated with reflection layer outward.The effect of gas inlet and outlet is to be convenient to gas and light enters.Spiral fashion glass tube main body has increased light path, can reduce volume greatly simultaneously, and can use long wavelength's light source.The effect of reflection layer is a direct reflection light.
Import, outlet and glass tube main body are tangent line.Be convenient to be connected with miscellaneous part.
Spiral fashion glass tube main body is a circle or a multi-turn.Decide according to design needs length.
Principle of work:
The principle of work and the course of work are as follows: the utility model is formed gas concentration sensor as the critical piece of gas concentration sensor jointly with light source, gas circuit, finishes the function of detected gas concentration.During work, gas enters the glass tube main body by import, flows through spiral fashion glass tube main body by outlet output.Light enters the glass tube main body by import, through repeatedly reflecting in spiral fashion glass tube main body by outlet output.
Compared with prior art, the beneficial effect that the utility model gas concentration sensor absorbing light pond is had is: the glass tube main body adopts spiral fashion, absorbing light pond volume is little, simple in structure, owing to adopt the spiral fashion glass tube both to increase light path, can use long wavelength's light source, can long time continuous working, stable and reliable operation, absorbing light pond volume is shortened greatly, and the life-span that can use light source, use cost was low greater than 50000 hours, safeguard simple, the detection data precision is accurate, uses easily and grasps, and the absorbing light pond is cleaned convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Wherein: 1 glass tube main body, 2 imports, 3 outlets, 4 reflection layers.
Fig. 2 is the most preferred embodiment in the utility model gas concentration sensor absorbing light pond, is described further below in conjunction with 1 pair of the utility model spiral of accompanying drawing glass tube gas absorption light pond:
Embodiment
With reference to accompanying drawing 1: glass tube main body 1 an outside side is provided with import 2, opposite side is provided with glass tube outlet 3.Glass tube main body 1 is shape in the shape of a spiral.Import 2, outlet 3 are tangent line with glass tube main body 1.Import 2 and outlet 3 are positioned at light Chi Liangduankouchu separately.Reflection layer 4 adopts the silver-plated or technology of aluminizing to be plated in the outside of glass tube main body 1, and glass tube main body 1 can be for convenience detach.
The principle of work and the course of work are as follows: the utility model connects as one the composition gas concentration sensor as the critical piece of gas concentration sensor by link and light source, gas circuit, finishes the function of detected gas concentration.During work, gas enters glass tube main body 1 by import 2, flows through spiral fashion glass tube main body 1 by outlet 3 outputs.Light enters glass tube main body 1 by import 2, through repeatedly reflecting in spiral fashion glass tube main body 1 by outlet 3 outputs.
