fork density meter

Description fork density meter

Tuning fork density meter is the introduction of foreign advanced frequency tracking technology and the production of high-precision, high applicability vibration principle density meter, product design using plug-in installation, widely used in pipelines, open tank containers and closed tank containers In the medium density testing.
Tuning fork density meter sensor is composed of two piezoelectric crystals, one piezoelectric vibration, the other piezoelectric crystal vibration detection, tuning fork sensor built-in temperature sensor, the piezoelectric crystal vibration temperature compensation.

Features fork density meter

1. Adopting Germany piezoelectric ceramic piece, crossing gold process for ceramic piece to increase the inoxidizability of ceramic piece, thus increasing the service life of densitometer.
2. Fork vibration original piece adopts Japan's high performance original piece, in which installed 24 AD converter, and the accurate recognition for frequency is 0.01HZ, to ensure the  sensitivity and accuracy of density.
3.Fork density calibration adopts national density standard solution, to ensure the source and accurate of density. 
4.The current circuit is independent of fork vibration circuit, there is isolating anti-interference inner, reducing the influence to instrument from disturb. 
5. There is set density three point quick calibration, range adjust, current calibration etc function, to meet on-site working demands.  

6.Using high precision measuring density, is mainly used in power plant. 
7.Can not be affected by temperature, pressure and flow rate , the factor affecting measuring error Is less. 

Principle fork density meter

Fork sensors ---------- one pair  fork ceramic sheets
A piezoelectric ceramic is responsible for generating vibrations
A piezoelectric ceramic is responsible for collecting vibration
The fork is always vibrate in the resonant frequency of vibration
Fork in different densities ,the resonance frequencies was different,.according to the relationship between the different vibration and density to calculate the density
The resonance frequency of the tuning fork is between 1600-2400
The higher the frequency the smaller density.
