Abstract
The invention discloses a vibration measurer, relating to the technical field of the application of a sensor. The vibration measurer comprises a circular magnet base and a vibration sensor connected with the magnet base through a nylon double-screw bolt, wherein an insulating gasket is arranged between the magnet base and the vibration sensor; the vibration sensor is sleeved inside an insulating housing; a filler is arranged between the insulating housing and the vibration sensor; the insulating gasket is a polytetrafluoroethylene gasket; the insulating housing is a nylon housing; and the insulating filler refers to an insulation paste. Compared with the prior art, as the vibrator sensor is insulated from the surrounding, an IGBT (Insulated Gate Bipolar Transistor ) inside a controller may not be damaged due to the grounding of the housing of the vibration measurer or low grounding resistance.
Description
Technical field
The present invention relates to the sensor application technical field, especially a kind of sensor that in oscillating aging equipment, is used to detect vibration.
Background technology
In oscillating aging oscillation pickup be used for detecting shaken part resonant frequency and convert electric signal to, controller carries out speed governing according to the electric signal passed back to the direct current generator on the vibrator, at the subresonance frequency part is implemented oscillating aging and handles; The technical scheme of existing a kind of oscillation pickup is: magnetic support and the vibration transducer that is connected with said magnetic support through metallic stud that a circle is arranged; An electrode of this vibration transducer is connected with the metal shell of vibration transducer, and another electrode is connected with internal circuit.
In use there is following deficiency in this technical scheme: an electrode of vibration transducer is a conductor that is communicated with through metallic stud and magnetic support; The oscillation pickup of this structure just can cause the inner insulated gate bipolar transistor (IGBT) of controller that is connected with this oscillation pickup to damage when the earthing of casing or stake resistance are too small.
Summary of the invention
Technical matters to be solved by this invention provides a kind of when the earthing of casing or stake resistance are too small, the oscillation pickup that the inner insulated gate bipolar transistor (IGBT) of controller can not damage.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of oscillation pickup; Include the magnetic support and the vibration transducer that is connected with said magnetic support through the nylon double-screw bolt of a circle; Be provided with insulation spacer between said magnetic support and the said vibration transducer; Said vibration transducer is sleeved in the insulation crust, is provided with filling material between said insulation crust and the said vibration transducer.
In the above-mentioned clamp technology scheme, technical scheme can also be more specifically: said insulation spacer is a teflon gasket; Said insulation crust be nylon outer shell; Said insulation filler is an insulating gel.
Owing to adopted technique scheme; The present invention compared with prior art; The beneficial effect that has is: because vibration transducer and insulation on every side, the inner insulated gate bipolar transistor (IGBT) of controller can not damage because the oscillation pickup earthing of casing or stake resistance are too small.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is made further detailed description:
Oscillation pickup as shown in Figure 1; The magnetic support of being processed by permanent magnetic material 1 is arranged; Vibration transducer 4 is contained in magnetic support 1 top, and vibration transducer 4 is connected with magnetic support 1 through nylon double-screw bolt 3, between magnetic support 1 and the vibration transducer 4 teflon insulation pad 2 is housed; The head of vibration transducer 4 stretches out cable 7, and these cable 7 parts are identical with prior art; The magnetic support 1 outer nylon tube shell 6 that is with, the height of shell 6 is greater than the height sum of magnetic support 1 with vibration transducer 4; Be filled with insulating gel 6 between vibration transducer 4 and the shell 6.Though an electrode of vibration transducer 4 is connected with metal shell, vibration transducer 4 with insulate on every side, the inner insulated gate bipolar transistor (IGBT) of controller can not damage because the oscillation pickup earthing of casing or stake resistance are too small.
