Abstract
The invention relates to the electrical element technology field and especially relates to a gas pressure sensor. The gas pressure sensor comprises a shell, a sylphon, an inductance coil, a magnetic core and a conversion circuit. The shell is divided into two portions which are an upper portion and a lower portion. The sylphon is arranged in the lower portion of the shell. The inductance coil and the magnetic core are arranged in the upper portion of the shell. The magnetic core is connected with the sylphon. The inductance coil is connected with the conversion circuit. The gas pressure sensor has a wide measuring scope. Precision is high. Input and output linearities are good. There are no magnetic saturation and ferromagnetic resonance phenomena. Operation is safe and reliable. The sensor has complete functions. Usage is convenient. The sensor can be served as a sensing component of the electronic system used for measuring and protection. The size is small and weight is light. A price performance ratio is high. There is no noise pollution. Anti-interference performance and a superior environmental protection characteristic are possessed.
Description
Technical field
The present invention relates to a kind of sensor, relate in particular to a kind of gas pressure sensor.
Background technology
In electric system; electromagnetic transformer is mostly adopted in the measurement of voltage and enforcement relay protection; the problem that this mutual inductor exists is that volume is large, Heavy Weight; measurement range is narrower; the ferroresonance phenomenon occurs easily; increase measuring error and the misoperation that causes protective relaying device, also potential safety hazard can occur when serious.At present, development along with electric system, the continuous increase of power capacity and electronic system are to networking, robotization and digitizing future development, and the required input signal of secondary device significantly reduces, and therefore this traditional sensor is difficult to satisfy technical requirement.
Summary of the invention
The technical problem to be solved in the present invention is: in electric system; electromagnetic transformer is mostly adopted in the measurement of voltage and enforcement relay protection; the problem that this mutual inductor exists is that volume is large, Heavy Weight; measurement range is narrower; the ferroresonance phenomenon occurs easily; increase measuring error and the misoperation that causes protective relaying device, also potential safety hazard can occur when serious, a kind of gas pressure 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 gas pressure sensor comprises housing, bellows, telefault, magnetic core and change-over circuit, described housing is divided into up and down two parts, be provided with bellows in the lower part of housing, be provided with telefault and magnetic core in the upper part of housing, described magnetic core is connected with bellows, and described telefault connects change-over circuit.
According to another embodiment of the invention, comprise that further described telefault is positioned at the sidewall of part on the housing.
The invention has the beneficial effects as follows: this gas pressure sensor measurement range is wide, and precision is high, and input, output linearity degree are good; Without magnetic saturation and ferroresonance phenomenon, it is safe and reliable to operation; Multiple functional, easy to use, can be used as the measurement of electronic system and the sensing element of protection usefulness; Volume is little, and is lightweight, and performance and price is higher; Noise-less pollution, anti-interference, have superior environmental protection characteristic.
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, housing, 2, bellows, 3, telefault, 4, magnetic core, 5, change-over circuit.
Embodiment
This gas pressure sensor comprises housing 1, bellows 2, telefault 3, magnetic core 4 and change-over circuit 5, described housing 1 is divided into up and down two parts, be provided with bellows 2 in the lower part of housing 1, be provided with telefault 3 and magnetic core 4 in the upper part of housing 1, described magnetic core 4 is connected with bellows 2, and described telefault 3 connects change-over circuit 5.
This gas pressure sensor is that direct feeling is measured, and output and the measured a kind of physical quantity element that becomes to determine relation, wherein bellows 2 is exactly sensitive element, come round with atmospheric pressure in its outside, inner impression is by measuring pressure, atmospheric variation causes that the bellows first half moves, and namely exports corresponding displacement.The input of change-over circuit 5 is exactly the output of sensitive element, can convert input to circuit parameter.
This gas pressure sensor measurement range is wide, and precision is high, and input, output linearity degree are good; Without magnetic saturation and ferroresonance phenomenon, it is safe and reliable to operation; Multiple functional, easy to use, can be used as the measurement of electronic system and the sensing element of protection usefulness; Volume is little, and is lightweight, and performance and price is higher; Noise-less pollution, anti-interference, have superior environmental protection characteristic.
