Abstract
The utility model discloses a kind of circulating carbon dioxide detector, is applicable to the test of gas concentration lwevel in airtight grain heap.This device comprises the gauge tap be connected with linear power supply successively by conductor wire, the minitype gas pump circulated for gas, carbon dioxide sensor, sensor assembly with digital display, and the sensor module package of described carbon dioxide sensor and digital display is reserved in both sides into and out of in the air chamber of pore; Described air chamber air admission hole is connected by the gas outlet of wireway with minitype gas pump, the venthole of described air chamber is connected by the air intake opening of wireway with casing to be measured, the air intake opening of described minitype gas pump is connected by the gas outlet of wireway with casing to be measured, forms sealing and circulating loop.The utility model utilizes closed gas-flow loop to improve the homogeneity of distribution of gas in environment to be measured to improve the representativeness of detection; Meanwhile, the backflow make-up gas loss of gas, ensures the accuracy measured, realizes monitoring the on-line continuous of inside.
Description
Technical field
The utility model relates to a kind of proving installation characterizing gas concentration lwevel in airtight grain heap, especially can read faint gas concentration lwevel change fast.
Background technology
At present, the carbon dioxide detector of market circulation, according to its gas collecting model split, is mainly diffusion type and pump suction type.Diffusion type carbon dioxide detector detects by being inserted in environment to be measured by instrument, can realize continuous detecting, but is unfavorable for realizing outside manipulation easily, and its placement position also will produce considerable influence to testing result.Gas sucking-off in environment to be measured realizes detecting by gas pump by pump suction type carbon dioxide detector, have good outside handling, but the gas of its sucking-off can cause the air-loss in testing environment, be unfavorable for realizing continuous detecting.
Summary of the invention
A kind of outside that the purpose of this utility model provides for above-mentioned the deficiencies in the prior art part is just handling good and can realize the circulating carbon dioxide detector of continuous detecting.
The purpose of this utility model can be realized by following technique measures:
Circulating carbon dioxide detector of the present utility model comprises the gauge tap be connected with linear power supply successively by conductor wire, the minitype gas pump circulated for gas, carbon dioxide sensor, sensor assembly with digital display, and described carbon dioxide sensor and the sensor module package with digital display are reserved into and out of in the air chamber of pore in both sides; Described air chamber air admission hole is connected by the gas outlet of wireway with minitype gas pump, the venthole of described air chamber is connected by the air intake opening of wireway with casing to be measured, the air intake opening of described minitype gas pump is connected by the gas outlet of wireway with casing to be measured, forms sealing and circulating loop.
The beneficial effects of the utility model are as follows:
The formation in closed gas-flow loop, contributes to being uniformly distributed of gas in environment to be measured, improves the representativeness of detection.The backflow of gas can supplement the loss caused owing to detecting sucking-off gas, ensure that the accuracy repeatedly measured, also achieves simultaneously and monitor the on-line continuous of inside at environmental externality to be measured.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, circulating carbon dioxide detector of the present utility model comprises the gauge tap 2 be connected with linear power supply 1 successively by conductor wire 8, the minitype gas pump 3 circulated for gas, carbon dioxide sensor, sensor assembly 5 with digital display, and described carbon dioxide sensor and the sensor assembly 5 with digital display are encapsulated in both sides and reserve into and out of in the air chamber 4 of pore; Described air chamber 4 air admission hole is connected by the gas outlet of wireway with minitype gas pump 3, the venthole of described air chamber 4 is connected by the air intake opening of wireway with casing 6 to be measured, the air intake opening of described minitype gas pump 3 is connected with the gas outlet of casing 6 to be measured by wireway 7, forms sealing and circulating loop.
Operation using method of the present utility model is as follows:
Wireway 7 is connected with casing 6 to be measured, connect linear power supply 1, open gauge tap 2, minitype gas pump 3 works and forms gas flow loop, gas in casing 6 to be measured is sucked in the air chamber 4 of encapsulated sensor, detected value is presented on digital indicator by induction by the sensor assembly 5 with digital display, is back in casing 6 to be measured by the gas of suction by wireway 7 simultaneously.The reading of detected value needs certain stabilization time.
