Abstract
The utility model relates to a plastic package pressure sensor, comprising a plastic package housing, wherein a gas source connection pipe is arranged on the housing; characterized in that the gas source connection pipe comprises a straight pipe segment, and the outer wall of the outer end of the straight pipe segment is provided with at least one barb. In the utility model, the outer wall of the outer end of the straight pipe segment of the gap source connection pipe is provided with the barb, thereby being simple in structure; the interference connection between a soft pipe and the barb of the outer end of the straight pipe segment ensures good tightness, thereby increasing detection precision; and further the plastic package pressure sensor does not need a pipe clamp, thereby being convenient and fast in mounting and dismounting operation.
Description
Technical field
The utility model relates to a kind of sensor, especially relates to a kind of plastic package pressure transducer.
Background technology
Pressure transducer is a kind of sensor the most commonly used in the industrial practice, it is widely used in relating to numerous industries such as water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, medical treatment, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, pipeline in the various industrial automatic control environment.Plastic package is all having superiority aspect profile, weight, performance, cost and the availability, and it is easy to realize industrial automation, and therefore, the application that detects in low pressure is very extensive.
The source of the gas of existing plastic package pressure transducer is taken over and is generally straight tube or Taper Pipe, and flexible pipe is taken over source of the gas and is connected and fixed by pipe clamp, test and practical application in the attended operation of flexible pipe very inconvenient, and impermeability is bad, has affected the accuracy of detection of product.
The utility model content
The applicant is studied improvement for above-mentioned problem, and a kind of plastic package pressure transducer is provided, and is simple in structure, installs and removes convenient to operationly, and impermeability is good, improves accuracy of detection.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of plastic package pressure transducer comprises the plastic package housing, and source of the gas is taken over and is arranged on the described housing, and described source of the gas is taken over and comprised straight length, and the outer wall of the outer end of described straight length is provided with at least one barb.
Further:
Described housing comprises preformed shell and gland, and described source of the gas is taken over and is arranged on the described gland.
Described housing comprises preformed shell and gland, and described source of the gas is taken over and is arranged on the described preformed shell.
Technique effect of the present utility model is:
The disclosed a kind of plastic package pressure transducer of the utility model, the outer wall of the straight length outer end that source of the gas is taken over is provided with barb, simple in structure, flexible pipe is connected with the interference of the barb of straight length outer end and has guaranteed good impermeability, improve accuracy of detection, in addition, do not need to use pipe clamp, install and remove convenient to operation.
