And degree.The signal of telecommunication that traditional intelligence gas sensor mainly produces gas sensing property device passes through control unit, using warm and humid
Degree compensation, linear process scheduling algorithm are converted into readable concentration value, then using various serial port protocols, output digit signals, connect
Mouth unit is installed using gold plated pins pluggable mode corresponding with the gas detector main frame that corresponding construction and pin are defined, and is being used
On-site support hot plug, features above is finally to be replaced between gas with various sensor for convenience, allows intelligent gas to pass
Sensor is more convenient with the maintenance and repair of gas detector (transmitter) unit.
However, the stationary appliance used on market, is typically necessary intrinsic safety certification or needs certification of explosion protection, traditional intelligence
Can the design of gas sensor gas sensor air inlet portion structure typically adopt steel wire or waterproof ventilated membrane etc., when being inserted in gas
When on detector (transmitter), a tube structure with explosion-proof sintered meshwork of screwing in addition is needed, as shown in Figure 2.This design
Shortcoming first consist in, explosion-proof sintered meshwork has certain obstruction and adsorption, and sintered meshwork to flammable or toxic gas
With the uncertainty that air-sensitive interelement has distance and space, thus can not truly realize by different intelligent gas
Sensor is demarcated and is saved the demarcation to whole instrument.
Next, if during cylinder use during the position change of generation loosening or relatively intelligent gas sensor, intelligence
The initial demarcation numerical value of sensor and corresponding time can also occur different degrees of change, it is more likely that beyond Standard；
Again, traditional intelligence gas sensor causes it one in batch production process due to the limitation of this structure design
Cause property is very poor, it is impossible to after enough realizations are demarcated to independent intelligent gas sensor batch, be directly used in gas detector (transmitter)
On unit, it is necessary to which whole machine is demarcated, and greatly reduces production efficiency.
In sum, what traditional intelligent gas sensor can't be truly realizes plug and play, sensor list
Solely demarcate, the function of whole machine non-calibrating.

It is preferred that described sensor Stainless Steel Shell adopts face protected against explosion structure.
It is preferred that described sensor body includes gas sensor, control unit and Interface Terminal, described gas sensor
It is fitting to connection with control unit, described Interface Terminal is fixed on described control unit top.
It is preferred that described positioning seat is socketed with Interface Terminal by structure design.
It is preferred that described sensor cavity is built-in with the gas collection sponge of one and the straight surfaces brought into contact of explosion-proof sintered meshwork.
Most preferably, described gas collection sponge is cylinder, and there is vertical cylindrical bottom surface direction described gas collection sponge center
Air inlet.
It is preferred that described sensor cavity outer hoop has an O-ring, the O-ring is close to described sensor cavity.
It is preferred that described positioning seat and sensor cavity are connected by snap.
This kind of explosion-proof sintered meshwork integral and intelligent gas sensor is employed, because it have cured explosion-proof sintered meshwork and air-sensitive
Relative position and plenum space between element, is capable of achieving individually to demarcate explosion-proof sintered meshwork integral and intelligent gas sensor, i.e.,
Can be in different explosion-proof instrument (transmitter) plug and play, it is not necessary to carry out demarcation action again, can be in batch production process, only
Explosion-proof sintered meshwork integral and intelligent gas sensor is demarcated, is not required to that transmitter is also placed in Calibration Box, saved and demarcate
When space, improve production efficiency, and on-site customer Sensor section go wrong, product provider only will need to individually demarcate
Explosion-proof sintered meshwork integral and intelligent gas sensor sends client, and being changed by curstomer's site to use, without the need for product provider
Service technician is shown up again carries out demarcation action, improves service quality and efficiency, reduces service cost.
