Tuning Fork Density Meter Excellent Over Voltage Protection Structure
Working Principle of Tuning Fork Density Meter
The sensor works based on the vibration principle of the component part, which is the tuning fork part immersed in the liquid under test. The tuning fork part vibrates through an internal piezoelectric device fixed to the bottom end of the fork body. The oscillation frequency is measured by a secondary piezoelectric device fixed at the other end of the fork, and the signal is amplified by a circuit at the top. The liquid density is closely related to the vibration frequency of the liquid under measurement. When the density of the liquid under measurement changes, the vibration frequency of the liquid under measurement also changes. Through the equation, the density of the liquid under test can be accurately calculated
Design feature of Tuning Fork Density Meter
◎Suitable for measuring the density of tanks, pipes, and flowing or stationary media. Suitable for measuring high temperature, low temperature, high viscosity medium containing impurities.
◎ A microprocessor-based electronic conversion device that integrates signal processing, computation and diagnostic functions.
◎ Continuous on-line measurement of liquid density and temperature, high precision, more safe and reliable, can be directly used for production process control.
◎ It can directly communicate with PC through RS485 interface, and users can directly perform online contact configuration, fault diagnosis and data recording.
◎ While measuring density and temperature, you can calculate the basic density, concentration percentage, mass percentage, volume percentage and other parameters.
◎excellent overpressure protection structure, superior temperature stability, all welded sealing, solid and reliable design.
◎it is easy to install and use, and the data can be displayed by inserting liquid.
◎Simplify maintenance without regular cleaning
◎Calibration no need standard reference source, laboratory calibration,without process interruption
◎Intrinsically safe type can be used in hazardous sites, and sanitary type can be installed in food production sites
