Embodiment
About the wired acoustic emission device of three axles:
See Fig. 1, Fig. 2 and Fig. 3, the utility model relates to the wired voice sending sensor device of a kind of three axle, comprise the sensor base 2 for being fixed on test specimen, the back side of described sensor base is fixed with calibrate AE sensor, through hole 3 is offered along on the axis direction of described sensor, the data output lead of described calibrate AE sensor, through described through hole, is filled with sealer in described through hole.
Sensor base is fixed on test specimen, heat-shrink tube sealing is carried out again on test specimen, then aperture is offered in the corresponding position on heat-shrink tube, sensor base is exposed by aperture, by fastener (as: cord), aperture is tightened again, so just, can prevent oil from entering into heat-shrink tube inside by aperture, ensure that calibrate AE sensor normally works, that indirectly monitors in warranty test normally carries out.
It should be noted that, the sealer of filling in through hole can be cure silicone rubber.
Described test specimen is generally rock sample.
The lateral surface of described sensor base offers external thread, also comprises nut 1, the internal thread of described nut matches with described external thread.
