The temperature sensor has advantages of being scientific in design, being simple in structure, being high in measurement precision, being good in moistureproof, corrosion-proof, and mycete-proof performances, and being good in waterproof and dust-proof effect.
Description
Technical field
The utility model relates to a kind of temperature sensor, specifically, has related to a kind of temperature sensor of good airproof performance.
Background technology
Existing PT100 type temperature sensor, profile is thick, being of rude workmanship,, there is very large gap in simple set temperature sensor chip in housing between chip and housing, between connector lug and temperature sense probe and housing, there is gap, therefore, this temperature sensor sealing, three anti-effects and water proof and dust proof weak effect, in vibration environment owing to having gap between chip and housing, chip easily produces significantly vibrations, and then defective chip.The measurement range of existing PT100 type temperature sensor generally at 0 degree to 120 degree, can not meet low-temperature measurement requirement, in reply, during varying environment, due to temperature sensor self structure, be subject to unavoidably outside environmental impact, cause measuring inaccurate.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thereby a kind of design science, the temperature sensor that simple in structure, measuring accuracy is high, NBC protective performance is good are provided, and this temperature sensor has solved that traditional sensors sealing is poor, chip holds flimsy problem effectively.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of temperature sensor, it comprises housing, be arranged on the temperature sensor chip in described housing, the temperature sense probe being connected with this temperature sensor chip input end and the connector lug being connected with this temperature sensor chip output terminal, in described housing, be provided with fluid sealant packed layer, described fluid sealant packed layer wraps up described temperature sensor chip, described temperature sense probe and described connector lug are all arranged on described housing, between described temperature sense probe and described housing and be equipped with water proof rubber circle between described connector lug and described housing.
Based on above-mentioned, described temperature sensor chip is platinum resistance temperature sensor chip.
Based on above-mentioned, described housing is 304 Stainless Steel Shell.
Based on above-mentioned, described housing profile is column, and described temperature sense probe and described connector lug are separately positioned on the two ends of this housing.
The relative prior art of the utility model has substantive distinguishing features and progress, specifically, the utility model is different from traditional temperature sensor, in described housing, be provided with fluid sealant packed layer, described fluid sealant packed layer wraps up described temperature sensor chip, make to fill full fluid sealant between housing and described temperature sensor, increase by three anti-property and water proof and dust proof effects of whole temperature sensor; Adopt platinum resistance temperature sensor chip to make the measurement range of this temperature sensor wider; Meanwhile, set temperature inductive probe waterproof necklace and connector lug waterproof necklace, make three anti-property of whole temperature sensor good, water proof and dust proof is effective; It has advantages of design science, simple in structure, measuring accuracy is high, NBC protective performance is good and water proof and dust proof is effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of temperature sensor in the utility model embodiment.
Fig. 2 is the A-A cut-open view of Fig. 1.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of temperature sensor, it comprises housing 1, is arranged on the temperature sensor chip 4 in described housing 1, the temperature sense probe 2 being connected with these temperature sensor chip 4 input ends and the connector lug 3 being connected with these temperature sensor chip 4 output terminals, in described housing 1, be filled with the sealant 5 being formed by fluid sealant, described temperature sense probe 2 and described connector lug 3 are separately positioned on described housing 1, between described temperature sense probe 2 and described housing 1 and be equipped with water proof rubber circle between described connector lug 3 and described housing 1.
Described temperature sensor chip is platinum resistance temperature sensor chip, utilizes platinum resistance temperature sensor chip to increase the measurement range of this temperature sensor, makes this temperature sensor can be used in low temperature environment.
The sealant 5 that the interior filling of described housing 1 consists of fluid sealant; for the protection of temperature sensor chip 4; make three anti-property and the water proof and dust proof of whole temperature sensor effective; improve the working environment of this temperature sensor; increase the service life, three in the present embodiment prevents comprising protection against the tide, anticorrosion and mould proof.
Described housing 1 is 304 Stainless Steel Shell, adopts 304 Stainless Steel Shell, fills the sealant 5 consisting of fluid sealant in 304 Stainless Steel Shell, makes whole arrangement of temperature sensor compact, good looking appearance, and three anti-property and water proof and dust proof are effective.
For rational in infrastructure, described housing 1 profile is column, and described temperature sense probe 2 is arranged on described 304 Stainless Steel Shell upper ends, and described connector lug 3 is arranged on described 304 Stainless Steel Shell lower ends, in other embodiment, the position of set temperature inductive probe and connector lug as required.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
