The utility model discloses can realize the quick installation of sensor, show improvement temperature measurement speed, measured data is accurate, extensive applicability.
Description
Technical field
The utility model relates to a kind of temperature sensor, is specifically related to a kind of NTC temperature sensor.
Background technology
NTC temperature sensor ubiquity reaction velocity is in the market slow, and install complicated, take up room larger, versatility is poor.
Utility model content
For solving the problem, the utility model provides a kind of NTC temperature sensor, can improve reaction velocity during measuring tempeature, and measurement data is accurate, and volume is little can be arranged on testee by arbitrarily fitting, safe and reliable.
The technical scheme that the utility model provides is: a kind of NTC temperature sensor, comprises metal shell, thermistor, epoxy resin, insulation sleeve and pin; Thermistor is arranged in metal shell, is filled with epoxy resin between thermistor and metal shell; There are two pins at thermistor two ends, and two-layer insulation sleeve is coated on outside pin respectively, have epoxy resin, also have epoxy resin between insulation sleeve and metal shell between two-layer insulation sleeve; It is characterized in that: metal shell is the tubular of both ends open, its xsect outline is that top semicircular-shaped lower portion is straight or overall square.
As further improvement, the material of cylindrical metallic shell is aluminium or copper.
As further improvement, the material of insulation sleeve is Teflon or silica gel.
The utility model has following beneficial effect: temperature tests the speed and significantly improves, and measurement data is accurate, and install easily, applicability is wide.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the utility model NTC temperature sensor.
Fig. 2 is the schematic side view of the utility model NTC temperature sensor.
Fig. 3 is the cross-sectional schematic of the utility model NTC temperature sensor.
Embodiment
As shown in Fig. 1 ~ 3, a kind of NTC temperature sensor of the present utility model, comprises metal shell 1, thermistor 2, epoxy resin 3, insulation sleeve 4 and pin 5; Wherein metal shell 1 is the tubular elements of the both ends open be made up of aluminium or copper or the good metal material of other heat conduction, and its xsect outline is that top semicircular-shaped lower portion is straight or overall for square; Thermistor 2 is arranged in metal shell 1, is filled with epoxy resin 3 between thermistor 2 and metal shell 1; There are two pins 5 at thermistor 2 two ends, and two-layer insulation sleeve 4 is coated on outside pin 5 respectively, have epoxy resin 3, also have epoxy resin 3 between insulation sleeve 4 and metal shell 1 between two-layer insulation sleeve 4; Insulation sleeve 4 is made up of the material that the insulating property such as Teflon or silica gel are good.
