Description
Technical field
The utility model relates to a kind of vibration transducer, belongs to the watch-dog technical field.
Background technology
At present the plant equipment in a lot of industry long-time running imbalance often occurs, the mechanical fault such as misaligns, and when serious, also may cause the interruption of whole equipment to stop, and even may produce personal injury.Classic method is exactly the meticulous maintenance of dependence maintainer and work on the spot experience, observes and find.Meticulous maintenance can well improve the serviceable life of engineering goods, but but can not definitely avoid the generation of fault; The omen of all mechanical equipment faults is exactly generally the abnormal vibrations of sports equipment, by the monitoring to vibration, can effectively predict the appearance of fault.In case scent a hidden danger, just can check at any time, prevent the fault extension, elimination accident in advance.Therefore be used to the vibration transducer of surveying mechanical vibration, also just arisen at the historic moment.Voltage or electric charge output form are all adopted in the output of conventional vibration sensor, and voltage and charge signal transmission are easy to be subject to electromagnetic interference (EMI) and distorted signals; In addition, due to the rugged surroundings of industry spot, vibration transducer also often is subject to the infringement of impact shock and corrosion, causes the performance of vibration transducer to be affected.
In view of above-mentioned ubiquitous defect, can design, produce a kind of novel vibration transducer, to make up above-mentioned defect, be the technical barrier that those skilled in the art face.
Summary of the invention
The utility model aims to provide a kind of vibration transducer, and it has overcome the drawback of existing vibration transducer, can resist electromagnetic interference (EMI), anti shock and vibration and corrosion etc.
The technical scheme that the utility model adopts is as follows: described vibration transducer comprises conversion screw, isolation cushion block, sensor main body, signal output cable, and wherein, sensor main body comprises spring and motion components and parts, signal processing circuit, Stainless Steel Shell; Spring and motion components and parts are connected by isolating cushion block with the conversion screw, and signal processing circuit is connected with spring and motion components and parts, signal output cable respectively, and spring and motion components and parts and signal processing circuit are arranged in Stainless Steel Shell.
Preferably, spring and motion components and parts are Fibre Optical Sensor unit or inductance sensor unit.
Preferably, the signal output cable is shielded cable.
The utility model advantage compared to prior art is: 1, anti-electromagnetic interference capability strengthens; 2, anti shock and vibration; 3, anticorrosive.
The accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Symbol description: 10, conversion screw; 20, isolation cushion block; 30, sensor main body; 40, signal output cable; 301, spring and motion components and parts; 302, signal processing circuit; 303, Stainless Steel Shell.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated: as shown in Figure 1, this vibration transducer comprises conversion screw 10, isolation cushion block 20, sensor main body 30, signal output cable 40, wherein, sensor main body 30 comprises spring and motion components and parts 301, signal processing circuit 302, Stainless Steel Shell 303; Spring and motion components and parts 301 are connected by isolation cushion block 20 with conversion screw 10, signal processing circuit 302 is connected with spring and motion components and parts 301, signal output cable 40 respectively, and spring and motion components and parts 301 and signal processing circuit 302 are arranged in Stainless Steel Shell 303.
Isolation cushion block 20, for changing being connected and fixed between screw 10 and sensor main body 30, isolation cushion block 20 is made by special stainless steel material, have higher intensity and anticorrosive, anti shock and vibration and anti-electromagnetic interference capability, avoid undesired signal to import sensor main body 30 by conversion screw 10, affected the normal measurement of sensor and the normal operation of equipment.
Sensor main body 30, comprised housing, internal component and signal processing circuit etc.
Spring and motion components and parts 301, for the sense mechanism magnitude of vibrations, follow mechanical vibration and constantly do and shear the magnetic induction line motion, thereby produce electromotive force, magnitude of vibrations is converted to the size of electromotive force.This is very common in the prior art, can be for example optical fiber, inductance sensor unit, does not repeat them here.
The above is illustrated the utility model with way of example, but the utility model is not limited to above-mentioned specific embodiment, and all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
