Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of measuring instrument, especially a straight insertion type tuning fork density meter. BACKGROUND

[0002] The working principle of the straight insertion type tuning fork density meter is based on the vibration characteristics of the tuning fork. When the tuning fork is immersed in the measured medium, the density of the medium will affect the vibration frequency of the tuning fork. By accurately measuring the change of the vibration frequency of the tuning fork, the density of the medium can be calculated. It has high measurement accuracy and can provide accurate and reliable density data. Moreover, it has fast response speed and can monitor the change of the density in real time. However, when dirt, impurities or corrosion are attached to the surface of the tuning fork, the vibration characteristics of the tuning fork will change, resulting in decreased measurement accuracy, slower response speed, poor stability and increased error.

[0003] After searching, the Chinese patent document (authorized announcement number CN206146784U) discloses a tuning fork type online density meter, which aims to provide a tuning fork type online density meter which is not prone to measurement error after long-term use. The technical solution points are that the tuning fork type online density meter comprises a display screen, a flange plate, a mounting column, a straight insertion type tuning fork body and an arc-shaped groove. After the tuning fork type online density meter is used for a long time, the strain gauge is always in stable contact with the upper end of the straight insertion type tuning fork body due to the fact that the strain gauge is glued to the bottom of the slot, so that the connection between the straight insertion type tuning fork body and the strain gauge is more stable, and the detection of the vibration frequency of the straight insertion type tuning fork body by the strain gauge is more prepared. The setting of the arc-shaped groove effectively reduces the influence of the natural frequency of the straight insertion type tuning fork body on the strain gauge, so that the measurement result of the whole tuning fork type online density meter is more accurate, and the tuning fork type online density meter has the advantage of not being prone to measurement error after long-term use. Although the device can measure density, when dirt, impurities or corrosion are attached to the surface of the tuning fork, the vibration characteristics of the tuning fork will change, resulting in decreased measurement accuracy, slower response speed, poor stability and increased error.
