Below according to the drawings and specific embodiments, the utility model is described in further detail:
As Figure 1-3, a kind of high/low temperature pitman for car engine temperature sensor of the present utility model, including cylindrical metal sheath pipe 1, cylindrical metal sheath pipe 1 is internal is filled with insulant 2, and seal with high temperature sealing material 3 respectively at the internal two of cylindrical metal sheath pipe 1, insulant 2 and high temperature sealing material 3 inside are plugged with some lead-in wire electrodes 4, one end of lead-in wire electrode 4 is plugged in cylindrical metal sheath pipe 1 for connecting temperature element, the other end of lead-in wire electrode 4 extends to and connects for external circuit outside cylindrical metal sheath pipe 1；Lead-in wire electrode 4 two exit adopts glass glaze 3 to carry out partially sealed closing。
Wherein, lead-in wire electrode 4 is with the axis of cylindrical metal sheath pipe 1 for axial symmetry；The quantity of lead-in wire electrode 4 is two, three, four or the six roots of sensation。
Wherein, lead-in wire electrode 4 is metal wire material or the thermocouple alloy wire of super-low resistance；Cylindrical metal sheath pipe 1 is high temperature resistant stainless steel material；Insulant is high purity magnesium oxide。
Time specifically used, one end that the high/low temperature pitman being used for car engine temperature sensor exposes electrode connects temperature element, then with a butt tube closed temperature element closed and be welded on cylindrical metal sheath pipe and do measurement end together, the other end exposing electrode connects temperature sensor termination (such as rosette, connector), namely be may be connected to temperature controller by wire and uses。
But, above-mentioned detailed description of the invention is illustrative of, and is to better make to skilled artisans appreciate that this patent, it is impossible to be not understood as this patent is included the restriction of scope；As long as any equivalent change made according to the disclosed spirit of this patent or modification, each fall within the scope that this patent includes。
