Abstract
The utility model discloses a oxygen transducer which comprises a base and a sensory unit, wherein both sides of the base is arranged between a admitting port and an air outlet, both of which is connected with a inductive air chamber, wherein the inductive air chamber is hermetically connected with the inductive air chamber and the sensory unit. On the upper part of the base is provided with a safety cover which plays a role of not only safeguarding the sensory unit but also isolating the sensory unit from contacting with air. A fluid sealant is injected within a hollow cavity between the safety cover and the sensory unit, which isolates the sensory unit from contacting with air. The utility model has the advantages of improving the quick reactive speed and sensitivity of the oxygen transducer, simple structure, low cost for production and having a relatively high service value and spreading value.
Description
Technical field
The utility model relates to a kind of oxygen measurement device, relates to a kind of oxygen sensor specifically.
Background technology
Used oxygen sensor is diversified at present; as United States Patent (USP) NO6; 477; a kind of oxygen sensor shown in 887; this sensor comprises traditional detection oxygen concentration and is translated into the sensing element of electric signal; insulation setting element with a through hole spare; by through hole sensing element is located; one can be by the sealing localization part in gap between glass-sealing agent sealed insulation setting element and the sensing element; sealing location step part is positioned sensing element to insulate in the setting element; be arranged to and each terminals that contact since the outstanding contact force of insulation setting element of sensing element; and outwards export from sensing element; be arranged in the upper surface of insulation setting element and support the terminals insulation supporter of terminals; be disposed in the outer peripheral face of insulation setting element and the hold-down support of fixed insulation setting element; the first terminal fastening hold-down support and cover terminals insulation supporter outer peripheral face outer cover and at the second terminal fastening hold-down support and cover from the protective cover of the outstanding sensing element outer peripheral face of insulation setting element; this oxygen sensor is to come fastening gas outlet by the threaded engagement on hold-down support and the gas outlet; yet this oxygen sensor has the structure of double hyer insulation body; therefore need the additional hold-down support of supporting this insulation setting element; the characteristics of this sensor are that reflection is sensitive; but structure more complicated, cost of manufacture are also than higher.
