Description
Technical field
the utility model relates to a kind of sensor calibration apparatus, is specially a kind of four core sensor calibration apparatus.
Background technology
at present in field of gas detection, to demarcate before gas detection equipment enters gas detect environment, be calibrated by the numerical value of certain density Standard Gases to checkout equipment.When in gaseous environment, the kind of detected gas reaches four kinds, need to install the gas detection equipment with four core sensors, four kinds of sensors will be demarcated before use respectively.When there being inflammable gas in four core sensors, sensor outer housing will be designed to blast resistance construction, and the breathing equipment of blast resistance construction can have an impact to the demarcation of the strong gas of absorption affinity and detection.Calibration mask structure as traditional is from centre position air inlet, and four sensors are uniformly distributed in surrounding, and because air intake opening is not direct alignment sensor, the gas T90 response time making absorption affinity strong does not reach standard.
Summary of the invention
for above-mentioned technical matters, this full mold provides a kind of transducer calibration cover, its feature be air intake opening position can 360 degree freely adjust, air intake opening and sensing station being aligned, the response time of T90 can be improved when demarcating the gas of high adsorption capacity.
the technical scheme that the utility model adopts is: a kind of sensor calibration apparatus, comprise bottom cylindrical face, boss, cylinder-shaped thin wall ring, it is characterized in that: described bottom cylindrical face top connecting cylinder shape thin-walled ring and boss, it is inner that described boss is positioned at cylinder-shaped thin wall ring, and described bottom cylindrical face inside is provided with base bleed hole and air admission hole, and described boss inside is provided with the vent port corresponding with bottom cylindrical face and air admission hole.
described cylinder-shaped thin wall ring is provided with locating slot, and described cylinder-shaped thin wall ring surrounding is provided with multiple sides vent port.
described base bleed hole is two, and vent port corresponding on described boss is also two.
in the utility model, calibration mask structure comprises cylinder-shaped thin wall ring, endoporus groove, central boss and bottom cylindrical face.Described locating slot is positioned at cylinder thin-walled ring upper end, and the angle in order to adjust air intake opening makes it align sensing station, and adjustment angle can 360 degree of rotations.It is uniform that described four side vent ports are positioned at thin-walled ring surrounding, and its sectional position communicates with sensor wrap bottom space and is exhausted.Described air admission hole and two base bleed holes are positioned at central boss end face and pass bottom cylindrical face, and sample gas arrives boss end face and sensor contacts by air admission hole, then is vented by base bleed hole.
the beneficial effect of this full mold is: structure is simple, and proving operation is convenient, and the Demarcate Gas T90 response time realizing absorption affinity strong reaches standard value.
