Abstract
The invention relates to the sensor technology field and especially relates to a capacitive sensor. The capacitive sensor comprises a fixing pole plate 1, a shell, a spring sheet, a mass block, a fixing pole plate 2 and an insulator. The mass block is arranged in the shell. The fixing pole plate 1 and the fixing pole plate 2 are arranged on two sides of the shell. The spring sheet is arranged between the mass block and the shell. The structure of the capacitive sensor is simple. Measurement precision is high. A frequency response range is wide and a measuring range is large. A detected body can be detected in a in certain range.
Description
Technical field
The present invention relates to a kind of sensor, relate in particular to a kind of capacitance type sensor.
Background technology
At present, capacitance type sensor can be used for flow, the pressure of liquid, gas and steam, the detection of liquid position and density etc.Existing structure when detected body is distant, just can't detect the existence of detected body in practical operation, only have when object from close to the time, just can be detected, so it is always limited to detect distance.And in the prior art, the complex manufacturing technology of capacitor, volume is large, and installation and use are all very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is: in the prior art, and the complex manufacturing technology of capacitor, volume is large, and installation and use are all very inconvenient, and a kind of capacitance type sensor is provided.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: this capacitance type sensor comprises fixed polar plate one, housing, spring leaf, mass, fixed polar plate two and insulator, be provided with mass in the described housing, be provided with fixed polar plate one and fixed polar plate two between the described housing, be provided with spring leaf between described mass and the housing.
According to another embodiment of the invention, the both sides that further comprise described fixed polar plate one are provided with insulator.
According to another embodiment of the invention, the both sides that further comprise described fixed polar plate two are provided with insulator.
The invention has the beneficial effects as follows: this capacitance type sensor simple in structure, measuring accuracy is higher, and frequency response range is wide, and range is large, and detected body can both be detected within the specific limits.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
Wherein: 1, fixed polar plate one, 2, housing, 3, spring leaf, 4, mass, 5, fixed polar plate two, 6, insulator.
Embodiment
Fig. 1 is structural representation of the present invention, comprise fixed polar plate 1, housing 2, spring leaf 3, mass 4, fixed polar plate 25 and insulator 6 among the figure, be provided with mass 4 in the described housing 2, be provided with fixed polar plate 1 and fixed polar plate 25 between the described housing 2, be provided with spring leaf 3 between described mass 4 and the housing 2.Mass 4 is supported by spring leaf 3 and places in the housing 2 that is full of air, spring leaf 3 makes the natural frequency of system higher more firmly, therefore consist of the duty of inertia-type accelerometer, when the linear acceleration on the measurement vertical direction, housing 2 is fixed on the tested vibrating mass, the vibration of vibrating mass makes the motion of housing relative mass piece, thereby two fixed polar plates 1 that are fixed together of housing 2 and fixed polar plate 25 relative mass pieces 4 when moving to fixed polar plate 25 form electric capacity with mass 4, and fixed polar plate 1 and mass 4 composition electric capacity, one of an increase reduces, and difference is proportional to by measuring acceleration.
The both sides of fixed polar plate 1 are provided with insulator 6.Insulator 6 has protective effect.
The both sides of fixed polar plate 25 are provided with insulator 6.Insulator 6 has protective effect.
This capacitance type sensor simple in structure, measuring accuracy is higher, and frequency response range is wide, and range is large, and detected body can both be detected within the specific limits.
