Abstract
The present invention discloses an omnidirectional used poisonous flammable gas sensor which comprises sensor main body, water cavity under the main body of sensor and water impervious but vapor permeable isolating film between water in cavity and main body of sensor. The structure of present invention is reasonable, and the said isolating film ensures good use effect and avoids damage to the main body of sensor from water. The service life of the present invention is long.
Description
Technical field:
The present invention relates to a kind of gas sensor.
Background technology:
Existing gas sensor, the bottom electrode of its sensor main body below directly is provided with water, between water and the sensor main body without hindrance every, easily be inverted in the use, during situation such as inclination, water directly contacts with electrode, causes sensor failure.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, not fragile, result of use is good can comprehensive use toxic combustible gas sensor.
Technical solution of the present invention is:
A kind of toxic combustible gas sensor that can comprehensive use comprises sensor main body, it is characterized in that: the sensor main body below is provided with water cavity, is provided with waterproof and barrier film vapor pervious between water in the water cavity and the sensor main body.
Sensor main body comprises upper and lower electrode, is provided with catalyst layer between the upper and lower electrode, and catalyst layer is located at semi-permeable diaphragm central authorities, and the upper and lower faces of catalyst layer is coated with carbon film.Be provided with plastic film in the carbon film periphery, plastic film, semi-permeable diaphragm, top electrode are arranged in the rubber seal, and rubber seal is connected with bottom electrode.Sensor main body is arranged in the end walls of water cavity opening part.
The present invention is rational in infrastructure, is provided with waterproof between water in the water cavity and the sensor main body and barrier film vapor pervious had both guaranteed good result of use, has avoided the water may be to the infringement of sensor main body again.Long service life.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of one embodiment of the invention.
Fig. 2 is the configuration diagram of sensor main body.
Embodiment:
