Embodiment Construction
[0012] Such as figure 1 A vibrating wire detection element shown includes a steel string 2, a support 1, a diaphragm 4 and a permanent magnet 3. One end of the steel string 2 is fixedly connected to the support 1, and the other end is fixedly connected to the diaphragm 4. The middle part of said steel string 2 is provided with permanent magnet 3. The steel string 2 is surrounded by the magnetic field formed by the permanent magnet 3 .
[0013] The vibrating wire detection element of the present invention uses the elastic element to change its natural frequency under the action of force or pressure, and convert the force into a frequency signal output, which is convenient for data transmission, processing and storage, and has small size, light weight, and high resolution. advanced features. Since the output signal is a vibration frequency signal, it is easy to be used directly with digital detection systems such as computers.

The invention discloses a vibration wire type detection element. The detection element comprises a string wire, a bearing, a membrane and a permanent magnet, wherein one end of the string wire is fixedly connected with the bearing, and the other end of the steel wire is fixedly connected with the membrane and the permanent magnet is arranged in the middle of the steel wire. According to the vibration wire type detection element provided by the invention, the data is convenient to transport, process and store in such a way of converting the acting force into frequency signals output because the inherent frequency of an elastic element is changed under the force or pressure effect, therefore, the detection element has the characteristics of being small in volume, light in weight, high in resolution and the like; furthermore, the output signal is a vibrating frequency signals, the detection element is likely to be directly matched with a computer and other digital detection systems.
Description
technical field [0001] The invention relates to the field of detection equipment, in particular to a vibrating wire type detection element. Background technique [0002] In the mechanical field, many physical quantities (such as pressure, flow rate, temperature, etc.) that are difficult to measure directly need to be measured by means of mechanical detection elements. However, the current mechanical detection element has complex structure, large volume, cumbersome operation during measurement, and low resolution. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention provides a vibrating wire detection element, which can completely solve the above-mentioned technical problems. [0004] The technical scheme that solves the above-mentioned technical problem is as follows: [0005] A vibrating wire detection element, including a steel string, a support, a diaphragm and a permanent magnet, on...
