For the gas concentration sensor of measure gas concentrations, described gas concentration sensor is located on described mount pad, and described gas concentration sensor is connected with described gas outlet, and air-flow enters described gas concentration sensor by described vapour lock.
Therein in an embodiment, the uninterrupted of the air-flow by described vapour lock can make the Bas Discharged in described gas concentration sensor.
In an embodiment, described vapour lock is tubule therein, and the aperture of described tubule is 0.9-1.0 millimeter, and the shunt ratio of described vapour lock is less than or equal to 10%.
In an embodiment, described vapour lock is the through hole that is opened in described gas concentration sensor air intake opening therein, and the aperture of described through hole is 0.9-1.0 millimeter, in the shunt ratio 10% of described vapour lock.
In an embodiment, described gas concentration sensor is oxygen concentration sensor therein.
Above-mentioned by-pass flow gas concentration inspect device is by being provided with vapour lock, and the flow of the air-flow that passes through gas concentration sensor making reduces greatly, prevents the flushing gas concentration sensor of the air-flow of large flow.In the time that equipment does not move, vapour lock also can prevent from entering into more oxygen in gas concentration sensor, and to prevent that gas concentration sensor is for a long time under high concentration environment, life-span and measuring accuracy to gas concentration sensor impact.Therefore, above-mentioned by-pass flow gas concentration inspect device has longer serviceable life, and guarantees measure gas concentrations comparatively accurately.
Brief description of the drawings
