Abstract
The utility model provides a pressure sensor. A problem that parameters of an existing pressure sensor can not be adjusted is mainly solved. The pressure sensor comprises a circuit board mounting seat (1) and a spring mounting seat (2). The circuit board mounting seat (1) is internally provided with a circuit board (3) and a Hall integrated circuit (4). The circuit board (3) and the Hall integrated circuit (4) are fixedly connected. The spring mounting seat (2) is internally provided with a compression spring (5), a magnet seat (6) and a magnet (7). The magnet seat (6) is embedded with the magnet (7). The compression spring (5) is at an outer side of the magnet seat (6). The pressure sensor is characterized in that the circuit board mounting seat (1) and the spring mounting seat (2) are in screw-thread fit. According to the pressure sensor, the adjustment of the parameters is realized, and the range of use is greatly improved.
Description
Technical field
The utility model relates to a kind of sensor, is specifically related to a kind of pressure transducer.
Background technology
Pressure transducer is a kind of sensor the most commonly used in the industrial practice, it is widely used in various industrial automatic control environment, relates to numerous industries such as water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, pipeline.
Hall chip pressure transducer is made according to Hall effect, namely utilizes Hall element to convert Hall voltage to by the displacement of the caused flexible member of pressure, thereby realizes the measurement of pressure.
But the force value that existing Hall chip pressure transducer detects is a fixing scope, and value range is non-adjustable, and namely parameter is non-adjustable, so just greatly reduces the scope of use.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of pressure transducer, has mainly solved the nonadjustable problem of existing pressure transducer parameter, and this pressure transducer has realized that parameter is adjustable, has greatly improved the scope of using.
The technical scheme that the utility model adopts is: a kind of pressure transducer, comprise wiring board mount pad (1), spring mounting seat (2), be provided with wiring board (3) and Hall integrated circuit (4) in the wiring board mount pad (1), wiring board (3) is fixedly connected with Hall integrated circuit (4), be provided with Compress Spring (5) in the spring mounting seat (2), magnetic receiver (6), magnet (7), the upper magnet (7) that embeds of magnetic receiver (6), Compress Spring (5) is in the outside of magnetic receiver (6), and wiring board mount pad (1) is threaded engagement with spring mounting seat (2).
Described spring mounting seat (2) screw in the wiring board mount pad (1).
The beneficial effects of the utility model are: owing to take technique scheme, realized that parameter is adjustable, greatly improved the usable range of this pressure transducer.
