Inside sphere type vector vibration transducer

Abstract

The invention relates to an inside sphere type vector vibration transducer, four through holes are arranged on a spherical container of a hollow uninsulated sphere, four peaks of a rectangular pyramid are formed among the four through holes, cylindrical point-touch transducers are respectively fixed in the four through holes, and each point-touch transducer is in the structure that a hexagon headbolt can connect an outside lead wafer and is hung in the point-touch transducer, the top of an impact connecting bar is fixed with the top of a connecting bar supporting spring, the bottom of the impact connecting bar is fixed with a hook ring of the impact connecting bar, and the bottom of the connecting bar supporting spring is fixed with the bottom of the point-touch transducer. A spherical vibrator is placed in a spherical insulated shell, and the vibrator and the hook ring of the impact connecting bar are connected through four vibrator connecting lines in the same length. The sphericalvibrator is provided with proper voltage, the four point-touch transducers can directly acquire obvious digital signals when the vibrator is vibrated, a signal processing circuit is simple, and the system explosion-proof performance is excellent.

Description

technical field [0001] The invention belongs to the field of electrical component sensors, and relates to a vibration sensor manufactured by using the principle of inertial vibration measurement, which is widely used for long-term vibration of instruments and equipment in coal, electric power, petroleum, chemical industry, metallurgy, transportation, construction, military industry and other industries Monitoring and protection, especially for system online automatic detection and alarm system. Background technique [0002] Sensors for measuring vibration can be divided into: vibration displacement sensors, vibration velocity sensors and vibration acceleration sensors. According to different test reference coordinates, vibration sensors can be divided into relative vibration sensors and absolute vibration sensors. The former is used to measure the motion of the vibrating body relative to its vibration reference point, and the latter is used to measure the motion of the vibr...

Problems solved by technology

[0008] By adopting the above structure, the vibration state in the horizontal or vertical state can be measured, but when the vibration occurs, the signal obtained by the traditional inertial electromagnetic detection method is weak, and it is an analog signal, which needs to be processed by a complex amplifier circuit to obtain data
