Abstract

The utility model mainly relates to an intrinsically safe packaging structure of a temperature sensor, which comprises a temperature measuring cable, a long-pipe-shaped sheath with one closed end, a sealing cover and an insulating heat-conducting filler. The temperature measuring cable is placed in the long-pipe-shaped sheath with one closed end; a gap between the temperature measuring cable and the long pipe-shaped sheath is filled with the insulating heat-conducting filler; the sealing cover seals an open end of the long pipe-shaped sheath; and a lead wire of the temperature measuring cable is led out of an open hole of the sealing cover. The structure of the sensor safely and reliably isolates an electrical structure of the sensor with a measured medium, thereby being a new design with extensive practicability and progress.

Description

A kind of temperature sensor encapsulating structure
Technical field
The utility model relates to a kind of temperature sensor encapsulating structure, thereby electrical structure and the measured medium safe and reliable isolation safety that guarantees measured medium of this structure by making the thermometric device, the temperature sensor of this structure are very suitable for uses such as the very high occasion of safety and temperature control requirement such as oil terminal, inflammable thing warehouse, grain depots.
Background technology
Temperature sensor is one of senser element the most commonly used in modern industry and the daily life, and temperature sensor commonly used comprises thermopair, thermistor, analog integrated temperature sensor and digital integrated temperature sensor.
Because the difference of application, also there is very big-difference in the various request for utilizations to temperature sensor in the practical application.A lot of common thermometric occasions, only temperature sensor probe directly need be placed under the test environment and get final product, and some application scenario is if any facilities such as the oil plant storehouse of high fire protection requirement, chemicals warehouses, its electrical insulation properties and ageing resistance to temperature sensor probe all has very high requirement, at this moment must encapsulate temperature sensor comprehensively, it be become meet the version that Environmental security requires.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of temperature sensor encapsulating structure, makes the electric part of temperature sensor and test environment reach safe and reliable isolation.
The utility model is achieved through the following technical solutions: the utility model temperature sensor encapsulating structure comprises elongated tubular sheath, gland bonnet and insulating heat-conductive filler that measuring temp. wire cable, an end seal.The feature of this structure is: described measuring temp. wire cable is the multi-core cable that temperature sensor is installed, and is used for collecting temperature information; The elongated tubular sheath of described end sealing is used to take in and protect measuring temp. wire cable; Described gland bonnet is used in the openend sealing that guarantees under the prerequisite that the measuring temp. wire cable extension line can be drawn the elongated tubular sheath; Described insulating heat-conductive filler is used to fill the space between measuring temp. wire cable and the elongated tubular sheath tube wall.
2, wherein, the temperature sensor on the described measuring temp. wire cable can be an occasionally thermistor of digital integrated temperature sensor, analog integrated temperature sensor, thermoelectricity.
3, wherein, can be one also can be a plurality of to the temperature sensor quantity on the described measuring temp. wire cable.
4, wherein, the elongated tubular protective sleeve material of described end sealing can be that corrosion resistance good metal pipe also can be the good and heat conduction of a corrosion resistance nonmetallic pipe preferably.
5, wherein, the blind end of the elongated tubular protective sleeve of described end sealing can be a permanent closure type structure, also the enclosed construction that can be made up of detachable part.
6, wherein, described gland bonnet with the connected mode of elongated tubular protective sleeve can be threaded, pressing is connected, welding or bonding.
7, wherein, described gland bonnet can be that a part also can be the combination of several parts.
8, wherein, described insulating heat-conductive filler can be oils, lipid or powdery type material.
Advantage of the present utility model is: both made the electric part of temperature sensor and test environment carry out safe and reliable isolation by the insulating heat-conductive filler; by firm corrosion resistant elongated tubular sheath the whole sensor parts have been carried out effective protection again; thereby the security of temperature sensor and life-span are all significantly improved, and are a kind of new designs of practicality and progressive widely that has.

Fig. 2 is the application synoptic diagram of the utility model specific embodiment;
Embodiment
Below in conjunction with an accompanying drawing and a specific embodiment the utility model temperature sensor encapsulating structure is described in further detail.
Consult Fig. 1, the utility model temperature sensor encapsulating structure comprises elongated tubular sheath (104), gland bonnet (being made up of sealed screw (102) and sealing nut (103)) and the insulating packing (105) of measuring temp. wire cable (being made up of multi-core cable (101) and temperature sensor (106)), end sealing.The measuring temp. wire cable that has one or more temperature sensor (106) in this embodiment is placed in the elongated tubular sheath (104) of end sealing, be full of insulating heat-conductive filler (105) between measuring temp. wire cable and the sheath, the openend of elongated tubular sheath uses the gland bonnet of being made up of sealing nut (103) and sealed screw (102) to carry out airtight, thereby prevent packing leaking, prevent that simultaneously introduced contaminants from sneaking in the filler.The output terminal of measuring temp. wire cable is passed by the mesopore place of sealed screw.
In actual the use, as shown in Figure 2, the elongated tubular sheath (204) of this utility model temperature sensor is placed in the measured medium (205), and the extension line (203) of gland bonnet part (202) and measuring temp. wire cable is in outside the tank body (201), does not contact with measured medium.The electric part of temperature sensor just can be isolated fully with measured medium like this, and is effectively protected.
The above is the detailed description and the accompanying drawing of a preferred embodiment of the present utility model, is not that scope of the present utility model limits.For method and apparatus of the present utility model, all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
