In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of photometer sensor device is provided, is wrapped
Containing light source, the first lens group, the second lens group, light scattering room, photodetector and amplification circuit module；The indigo plant that the light source is sent out
Light enters light scattering room after the refraction of the first lens group and the second lens group, and the particle in tested gas enters light scattering room
It afterwards scatters the blue light originally along straightline propagation, forms scattering light, this dispersed optical signal becomes electricity after photodetector
Signal, the electric signal are amplified through amplification circuit module and carry out signal sampling for sampler, the signal obtained according to sampling
Intensity, you can calculate the mass particle concentration for being tested gas.
Preferably, it is mounted on anti-dazzling screen on first lens and the second lens, passes through the first lens and the second lens
Refraction after, the light source into light scattering room forms a half-light area in light scattering room；Particle in tested gas enters light

It shows）, after the refraction by the first lens 2 and the second lens 3, the light source 3 into light scattering room 4 forms one in light scattering room
A half-light area；Particle in tested gas makes the blue light originally along straightline propagation scatter after entering light scattering room 4, is formed and is dissipated
Light is penetrated, these scattering light increase the light intensity in the half-light area of light scattering room 4, and the variation of this light intensity becomes after photodetector 5
For electric signal, this electric signal is amplified through amplification circuit module 6 for sampler（It is not shown）Signal sampling is carried out, according to adopting
The signal strength that sample obtains, you can calculate the mass particle concentration for being tested gas.
The shell of photometer sensor device described in the utility model uses Magnet clamp, stable structure, reliable, knot
It is real.
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：
Photometer sensor device described in the utility model has the advantages that wide range of measurement, high resolution, has simultaneously
It is simple in structure, convenient for adjusting.
The specific application example that the above is only the utility model does not constitute the scope of protection of the utility model any limit
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
