Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1 to Figure 3, non-contact type magnetic patch floating type linear displacement transducer of the present utility model, comprises fixed support 1 and the housing 2 being connected with fixed support 1, and described housing 2 inside are provided with pcb board 3, and described pcb board 3 centres are provided with magnetic strength chip 4; Described housing 2 tops are provided with slide block 5, described slide block 5 and described housing 2 noncontacts; Described slide block 5 inside are provided with magnet steel 8; Described slide block 5 prolongs housing 2 transverse horizontal motions.Housing 2 two ends seal with end cap 9.
Between described pcb board 3 and housing 2, be packaged with epoxy resin 6, play the effect of insulation, sealing.
Described housing 2 one end are provided with draws wire 7, described in draw wire 7 and be electrically connected with described pcb board 3, draw wire 7 other ends for connecting outer transmitter.
Magnet steel 8 is preferably the SmCo magnet steel that magnetic energy product is large.
Magnetic strength chip 4 is preferably Hall chip.
In the time that needs are measured linear position, slided by corresponding actuating unit band movable slider, SmCo magnet steel in slide block produces change of magnetic field strength, adopt the Hall chip of three axle hall sensing technology, four groups of collection magnetic sheets changes of magnetic field of the direction of the vertical and level of inductive magnetic steel parts simultaneously in chip, and produce an output signal that is proportional to length in conjunction with Hall chip processor, realize its signal output by peripheral hardware programmable device.
The utility model non-contact type magnetic patch floating type linear displacement transducer adopts magnetic strength chip as core parts, and structure collectivity is simplified, and the cost of product is not high, in the occasion of measuring short and small stroke, has stronger advantage.
In sum, above-mentioned embodiment is not restricted embodiment of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
