Feature Tuning 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.
