Implication in the present invention.
Embodiment：
Below with reference to Fig. 1 to Fig. 4, a kind of fluid temperature sensor of the present utility model is described according to embodiment and
Explanation.
A kind of fluid temperature sensor includes：Electrical part (6), packaging part (7) and shell (5).
Electrical part (6) is identical with more than 2 nominal resistances by different pcb board (61), signal transmission wire (62)
Thermistor (63) compose in parallel.Wherein thermistor (63) in parallel and the wire at connection thermistor (63) both ends in parallel
(62), it is welded on pcb board (61), welds between the temperature sensor (63A) of good thermistor (63) and pcb board (61), leave
The gap for being available for flow of fluid more than 0.5mm.
Packaging part (7) is existing good fluidity, there is the good solidification under normal temperature or specified conditions again, can be by electricity after solidification
Device (6) tightly wraps up, and exempts from epoxy resin or silicon rubber fluid affected.
Shell (5) made of metal or nonmetallic materials, inner side have the accommodating cavity for being easy to encapsulate electrical part (6),
The side wall of accommodating cavity, which is provided with, prevents electrical part (6) from loading after accommodating cavity the back-off (51) deviate from, and outside, which is provided with, is easy to wire
(62) pass through, " 7 fonts intersection " cableties (53) of fixed wire (62), formed on the leg in interior outside, worn provided with wire (62)
Later the wire casing (52) of sensor (99) installation is not influenceed.
The fluid temperature sensor (99), it is to be arranged on electrical part (6) in the accommodating cavity of shell (5), with encapsulation
After part (7) is filling, coordinate between the temperature sensor (63A) and shell (5) and packaging part (7) of thermistor (63) in gap.Due to
