Description
technical field:
the utility model relates to a kind of quantum type infrared absorption type gas sensor.
background technology:
gas sensor can be used for the qualitative of gas or quantitatively detects.Chemistry or Physical interaction can be there is after gas sensitive contacts with gas, cause the change of its some characterisitic parameter, comprise quality, electrical quantity, optical parametric etc.Gas sensor utilizes these materials as gas sensor, the change of tested gaseous species or concentration is changed into the change of sensor output signal, thus realizes gas detect object.Traditional gas sensor comprises semiconductor gas sensor, catalytic combustion type gas sensor, Electro-chemical Gas Sensor.Semiconductor gas sensor detects gas concentration and kind by semi-conductor electricity change of properties before and after mensurated gas composition contact, but necessary hot operation, poor to gas-selectively; After catalytic combustion type gas sensor utilizes gaseous combustion to produce heat, increased resistance value is to detect gas concentration and kind, and shock resistance is poor, for toxic gas Low Response.
utility model content:
the purpose of this utility model is to provide a kind of quantum type infrared absorption type gas sensor.
above-mentioned object is realized by following technical scheme:
a kind of quantum type infrared absorption type gas sensor, its composition comprises: support, described frame upper is provided with measuring flume, described support bottom is provided with motor, element install bin, amplifier, display, quantum type infrared optical sensor is arranged in described install bin, described motor is connected with rotating disk, described rotating disk is provided with one group of optical filter, the outgoing mirror center of described measuring flume lower end, the center of optical filter and the center of described quantum type infrared optical sensor are point-blank, described display is connected with described amplifier, described amplifier is connected with described quantum type infrared optical sensor, described measuring flume upper end is provided with light source.
beneficial effect:
1. the principle of work of this quantum type infrared absorption type gas sensor is as described below: the vibration of majority of gas molecule and rotation spectrum are all at infrared band.When the frequency of incident IR radiation is identical with the vibration rotation feature frequency of molecule, infrared radiation will absorb by gas molecule, cause the decay of radiation intensity.The infrared light that infrared light supply produces incides measuring flume, and when being irradiated to certain tested gas, different according to gaseous species, have different absorption characteristics by the infrared light of different wave length, gas variable concentrations of the same race is also different to the uptake of infrared light.Therefore, by measuring the intensity of the infrared light arriving light activated element, kind and the concentration of tested gas just can be known according to the wavelength of infrared light supply and the electric signal of light activated element output.
after some material and specific gas contact reaction, its absorption spectrum at ultraviolet visible light wave band can change, and such as methyl red variable color can occur in acid atmosphere.Can in the detection of ultraviolet visible light wave band realization to gas as the coating of measuring flume inwall with this type of material.2. the utility model precision is high, selectivity good, air-sensitive degree wide ranges, can be applicable to the important monitoring means that the industrial sector production procedures such as iron and steel, petrochemical industry, chemical fertilizer, machinery control.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
