Description of Tuning Fork Density Meter 4-20mA 4 Wire Piezoelectric Tuning Fork Density Meter
Tuning fork density meter principle description:
Fork sensors ---------- one pair fork ceramic chip
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.

Features of 4-20mA 4 Wire Piezoelectric Tuning Fork Density Meter
1. Adopt Germany piezoelectric ceramic chip, with gold plated process to increase the oxidation resistance of ceramic chips, also can longer service life of density meter.
2. Fork vibration original chip adopt Japanese made high performance original chips, Built-in 24 AD converter, frequency identifying accuracy to be 0.01HZ, to warranty 3.the sensitivity and precision of the meter.3.Fork density calibration adopts national density standard solution, to ensure the source and accurate of density.
3. The current circuit is independent of fork vibration circuit, there is isolating anti-interference inner, reducing the influence to instrument from disturb.
. There is set density three point quick calibration, range adjust, current calibration etc function, to meet on-site working demands.
Application of 4-20mA 4 Wire Piezoelectric Tuning Fork Density Meter
Used in the petrochemical industry, wine industry, food industry, pharmaceutical industry and mineral processing (such as clay, carbonate, silicate, etc.), specifically for interfacial detection in multi-product pipelines in the above industries, mixing density Detection, reactor end monitoring, analyzer interface detection.
