The density of medium in open tanks and closed tanks is directly determined by the vibration frequency received by the tuning fork of the sensor inserted into the medium. The built-in temperature sensor of the sensor provides temperature compensation for it.
2. Scope of application: The plug-in density meter can perform density detection online in real time. It can be used for process control of products with density as the basic parameter or quality control with solid percentage or concentration percentage as a reference. Typical industries include petrochemical industry, wine industry, food industry,
pharmaceutical industry and mineral processing (such as clay, carbonate, silicate, etc.), which are specifically used in the interface detection and mixing of multi-product pipelines in the above industries The density detection, the end-point monitoring of the reactor, and the interface detection of the separator. The sensor works based on the principle of component vibration, and the component part is the part of the tuning fork immersed in the measured liquid. The tuning fork part induces vibration through an internal piezoelectric device fixed at the bottom end of the fork body. The oscillation frequency is detected by
a secondary piezoelectric device fixed at the other end of the fork body, and then the signal is amplified by the circuit on the top. The density of the liquid is closely related to the vibration frequency when the measured liquid flows. When the density of the measured liquid changes, the vibration frequency when the liquid flows also changes.
