Tuning Fork Density Meter

Standard export package

Fork density meter principle:
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.

Fork density meter parameter:

1 Density range :0-3 g / CM3 (3 /2.5/ 2 /1.5/ 1)

2 Output:4-20 mA  4-wire ( 2-wire system can not be used)

3 Accuracy:0.001 g / cc, with a resolution of 0.0001 g / cc

4 Insertion depth :(flange distance to the end of the fork, minimum 125 mm, up to 2 meters)

5 Display: Up density value, the density value can be switched to kg / cubic meter or g / cc by unit keys. Down display a temperature value (measured medium temperature ) temperature is original PT1000

6 Accessory:   temperature of 4-20 mA output signal

7 The internal circuit board with automatic filtering function, other vibrations like pipe vibrations can eliminate away from the side of circuit and software,which ensure accuracy.

Fork density meter strengths:

1.Application for high precision density measuring, mainly used in power plant.

2.Can not be affected by temperature, pressure and flow rate, there are few factor that can affecting measuring accuracy.

Fork density meter features:

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.

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.
