Abstract
The utility model provides a kind of NTC temperature sensors, including shell, thermistor, epoxy resin, silica gel and wire；Thermistor is arranged in shell；Wire one end is connected on thermistor, and shell is stretched out in one end；By silicone filler between thermistor and shell, filled between wire and shell by epoxy resin；Outer casing bottom is provided with through hole, and thermistor end is stretched into through hole, concordant with outer casing bottom outerplanar.Of the present utility model to be beneficial in that, thermistor directly contacts testee, high sensitivity and measurement is accurate.
Description
Technical field
It the utility model is related to a kind of temperature sensor, and in particular to a kind of NTC temperature sensors.
Background technology
Thermistor all embeddings of current NTC temperature sensors inside the housing, therefore heat must first go through shell biography
Pass thermistor, reflection speed is slow, and heat be present thermistor process contact is bad to be caused to survey being passed to by shell
It is larger to measure error.
Utility model content
The utility model provides a kind of fireballing temperature sensor of reflection, and measuring speed is fast and measuring accuracy is high.
The utility model provides following technical scheme：A kind of NTC temperature sensing devices, including shell, thermistor,
Epoxy resin, silica gel and wire；Thermistor is arranged in shell；Wire one end is connected on thermistor, and one end is stretched out outer
Shell；By silicone filler between thermistor and shell, space is filled by epoxy resin in remaining shell；Outer casing bottom is provided with
Through hole, thermistor end are stretched into through hole, concordant with outer casing bottom outerplanar.
Of the present utility model to be beneficial in that, thermistor directly contacts testee, high sensitivity and measurement is accurate.
Brief description of the drawings
Fig. 1 is schematic appearance of the present utility model.
Fig. 2 is sectional view of the present utility model
Embodiment
The utility model is described in detail as further below in conjunction with the accompanying drawings.
As shown in Fig. 1~2, the NTC temperature sensors mainly include shell 1, thermistor 2, epoxy resin 3, silica gel 4 and
Wire 5.Shell 1 is the tubular shell of both ends open, and its one end is temperature measuring head, and thermistor 2, temperature-sensitive electricity are provided with temperature measuring head
Hinder the outerplanar of the concordant outer casing bottom in 2 heads, it is exposed outside, testee can be abutted directly on.Wire 5 is welded on thermistor
On 2 pin, drawn from the other end of shell 1.Silica gel 4 is filled in thermometric head end, for fixing thermistor 2, and temperature-sensitive
Resistance 2 is sealed in shell 1.The poor fluidity of silica gel 4, and high temperature resistant, it is not easy to flow out shell.The embedding of epoxy resin 4 is in shell 1
Its interior complementary space, through hot setting again after the completion of embedding, wire is fixed in shell 1.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Above-mentioned embodiment, in those of ordinary skill in the art's possessed knowledge, the utility model can also not departed from
Made a variety of changes on the premise of objective.
