Abstract
The utility model discloses a kind of fixed wave length to detect detector, comprising: pedestal, pipe cap, collector lens, temperature sensor, detector chip and refrigerator, the pipe cap and the pedestal are fixed and form accommodating space between the pipe cap and the pedestal, the collector lens is embedded on the pipe cap, the temperature sensor and the refrigerator position are in the accommodating space, and setting is on the base, the detector chip is arranged on the refrigerator, and the accommodating space is filled with fixed concentration gas.Fixed wave length detection detector accuracy is high, at low cost, perfectly solves the problems, such as standard gas；Allow user that can carry out the research of the sorrow of no gas.
Description
Technical field
The utility model relates to gas detection technology fields, and in particular to a kind of fixed wave length detection detector.
Background technique
When carrying out gas detection, gas detection detector is generally used, however in existing technology, to dangerous gas
The detection of body has the following problems: the standard gas producer of hazardous gas is few, and is not easy to buy, even if purchase is also in specific environment
Middle use.
Utility model content
The purpose of this utility model is to provide a kind of fixed wave length detection detector for above-mentioned status, above-mentioned to solve
Problem.
The technical solution adopted in the utility model are as follows: a kind of fixed wave length detection detector, including pedestal, pipe cap, optically focused
Lens, temperature sensor, detector chip and refrigerator, the pipe cap and the pedestal are fixed and the pipe cap and the pedestal
Between form accommodating space, the collector lens is embedded on the pipe cap, and the temperature sensor and the refrigerator are located at
In the accommodating space, and it is arranged on the base, the detector chip is arranged on the refrigerator, and the accommodating is empty
Between be filled with fixed concentration gas.
The effect of the utility model is: fixed wave length detection detector accuracy is high, at low cost, perfectly solves standard gas
The problem of；Allow user that can carry out the research of the sorrow of no gas.
Detailed description of the invention
Fig. 1 show the structural schematic diagram of fixed wave length detection detector provided by the utility model.
Specific embodiment
The fixed wave length detection detector of the utility model is introduced with reference to the accompanying drawing:
As shown in Figure 1, detecting detector for a kind of fixed wave length provided by the utility model comprising pedestal 1, pipe cap 2,
Collector lens 3, temperature sensor 4, detector chip 5 and refrigerator 6, the pipe cap 2 fixed and described pipe cap with the pedestal 1
Accommodating space 7 is formed between 2 and the pedestal 1, the collector lens 3 is embedded on the pipe cap 2, the temperature sensor 4
And the refrigerator 6 is located in the accommodating space 7, and is arranged on the pedestal 1, the detector chip 5 is arranged in institute
It states on refrigerator 6, the accommodating space 7 is filled with fixed concentration gas 8.
The pedestal 1 be equipped with several connecting lines 11, the connecting line 11 respectively with the temperature sensor 4, the spy
It surveys device chip 5 and the refrigerator 6 connects.
Protrusion forms cavity in the middle part of the pipe cap 2, lens through-hole 21 is offered on the pipe cap 2, the collector lens 3 is embedding
It is located in the lens through-hole 21, the edge of the pipe cap 2 and the pedestal 1 are fixed, and the cavity seals shape by the pedestal 1
At the accommodating space 7.
The refrigerator 6 is semiconductor cooler.
The diameter of the photosurface of the detector chip 5 is not less than the diameter of the collector lens 3.
The center line of the collector lens 3 is overlapped with the center line of the detector chip 5.
In this present embodiment, the fixed concentration gas 8 is calibrating gas.
Fixed wave length detection detector accuracy is high, at low cost, perfectly solves the problems, such as standard gas；Allow user can be into
The research of sorrow of the row without gas.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
