Summary of the invention
The technical problem to be solved in the present invention there is provided and a kind ofly can ensure high sensitivity and the exhaust gas temperature sensor of working stability.
Technical scheme of the present invention is as follows:
A kind of exhaust gas temperature sensor, comprise housing, the outside of described housing is step-like structure, described step-like structure is from left to right successively by first step post, second step post, the 3rd step post and the 4th step post form, described second step post is greater than first step post, described first step post is greater than the 3rd step post, described 3rd step post is greater than the 4th step post, one section of external thread is equipped with in the outside of described first step post and the 4th step post, the middle part of described first step post left end is also connected with one section of heat conducting bar, and described heat conducting bar level is stretched out left; Shoulder hole is provided with in described housing, described shoulder hole to the right opening on the right side of the 4th step post, in described shoulder hole, be embedded with four-core aviation plug, the inside of described heat conducting bar is also provided with opening cavity to the right, this cavity be connected at the bottom of the hole of shoulder hole through; Left end in described cavity is filled with heat conductive silica gel, is inserted with PT100 platinum resistance thermometer sensor, in described heat conductive silica gel, and described PT100 platinum resistance thermometer sensor, stretches out heat conductive silica gel to the right and is connected and fixed with four-core aviation plug.
Adopt above structure, housing adopts step-like structure to alleviate case weight, one section of external thread is provided with in the outside of first step post and the 4th step post, can be spirally connected in installation site and associated components stationary housing, the situation that can effectively prevent housing from getting loose and to come off occurs, and arranges the very high heat conductive silica gel of heat sensitivity and PT100 platinum resistance thermometer sensor, effectively can measure real time temperature in housing, accuracy is high, and performance is better.
For the ease of fixed disassembly housing, as preferably, the outer shape of described second step post is regular hexagon.
For the ease of production and processing, as preferably, described housing and heat conducting bar are integrated machine add-on type.
In order to effectively resist the erosion action of working environment, as preferably, described housing and heat conducting bar are made by stainless steel material.
Beneficial effect: the present invention is provided with external thread and PT100 platinum resistance thermometer sensor, improves thermometric stability on the one hand, improves work efficiency; Also improve thermometric sensitivity, compact conformation on the other hand, reasonable in design, processing is simple, easy accessibility.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the cut-open view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the housing 1 etc. that the present invention is made up of stainless steel material forms, the outside of described housing 1 is step-like structure, described step-like structure is from left to right successively by first step post 21, second step post 22, 3rd step post 23 and the 4th step post 24 form, the outer shape of described second step post 22 is regular hexagon, this second step post 22 is greater than first step post 21, described first step post 21 is greater than the 3rd step post 23, described 3rd step post 23 is greater than the 4th step post 24, one section of external thread is equipped with in the outside of described first step post 21 and the 4th step post 24, the middle part of described first step post 21 left end is also connected with one section of heat conducting bar 3, described heat conducting bar 3 level is stretched out left, this heat conducting bar 3 is also made up of stainless steel material, described housing 1 and heat conducting bar 3 are integrated machine add-on type.
As shown in Figure 2, shoulder hole 11 is provided with in described housing 1, described shoulder hole 11 to the right opening on the right side of the 4th step post 24, four-core aviation plug 12 is embedded with in described shoulder hole 11, the inside of described heat conducting bar 3 is also provided with opening cavity 31 to the right, this cavity 31 be connected at the bottom of the hole of shoulder hole 11 through; Left end in described cavity 31 is filled with heat conductive silica gel 32, in described heat conductive silica gel 32, be inserted with PT100 platinum resistance thermometer sensor, 33, and described PT100 platinum resistance thermometer sensor, 33 stretches out heat conductive silica gel 32 to the right and is connected and fixed with four-core aviation plug 12.
Using method of the present invention is as follows:
As depicted in figs. 1 and 2, when the present invention is in the process used, when heat conducting bar 3 stretches into exhaust airstream, due to heat conductive silica gel 32 and PT100 platinum resistance thermometer sensor, 33 close contact, before changing, temperature sensor is in unsettled state in heat conducting bar 3, thus further increases serviceable life of the present invention; On the other hand before adding heat conductive silica gel 32, temperature sensor and the cavity of heat conducting bar 3 are not directly contact, outside heat suffered by heat conducting bar 3 only has and passes to temperature sensor sensor 2 by air radiation, this needs to spend certain sensitive time, temperature sensor just can measure the true temperature of measured position, and sensitivity is not high; And between heat conductive silica gel 32 of the present invention and the cavity inner wall of heat conducting bar 3, being in the state directly contacted, heat can pass to PT100 platinum resistance thermometer sensor, at short notice through heat conducting bar 3, thus can greatly improve reaction sensitivity of the present invention.
Meanwhile, outside housing 1 left and right two ends step post on be respectively provided with one section of external thread, being spirally connected fixing can prevent the situation getting loose and come off of housing 1 from occurring preferably, also can improve stability and accuracy that four-core aviation plug 12 exports data; Second step post 22 on housing 1, the shape outside it is regular hexagon, when locating bad force dismounting when being spirally connected, can carry out disassembling operations, further increase the stability of dismounting of the present invention and work with aids such as spanners.
These are only embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing instructions of the present invention and accompanying drawing content to do, is directly or indirectly used in the technical field that other are relevant, all in like manner within scope of patent protection of the present invention.
