The instrument performs full scale and Linearity Measurement correction of each gear through the PC interface, and its Measurement performance and functions reach the advanced level.
Features
1. The whole machine adopts an electric lifting device.
2. The host uses a 7-inch wide touch screen, which is easy to operate and displays rich information.
3. Using ARM chip processor, data processing speed is fast, the screen can display viscosity, shear rate, shear stress, speed, temperature, percentile torque, powerful human-machine interaction interface, stable and accurate speed.
4. Equipped with gigabit network port data communication transmission, the transmission is fast and reliable, and supports external U disk data storage.
5. Provide single point, continuous, and timing three data storage methods, and have password-protected temperature and viscosity correction coefficients, allowing users to correct themselves on the premise of having reliable and accurate data.
6. Support stepless speed measurement viscosity, input any speed can directly reflect the full scale under the rotor, convenient for users to select test conditions.
7. Support any exchange of various viscosity units.
8. When the torque is lower than 10% or higher than 90% Measurement range, the instrument will issue an alarm.
9. The RTD temperature probe can monitor and measure the sample temperature in real time, with an accuracy of 0.1 ° C and a temperature Measurement range of 0 ° C -100 ° C.
10. Equipped with DV data program-controlled analysis software, custom measurement programs can be downloaded to the instrument to achieve automation and personalized operation, with data collection, analysis, preservation and historical data comparison functions.
11. The main control board and the subdivision driver board are all made of patch technology, and the circuit design adopts a microcomputer processor, resulting in a reasonable and compact structure.
Principle
The instrument calculates and displays the apparent viscosity of the sample by measuring the shear stress of the rotor when swirling/spinning in the coal-water slurry sample at a specific speed according to the requirements of the national standard GB/T188564-2008. The instrument controls the speed through a microcomputer processor and collects data such as torque and temperature in real time, and combines preset measurement programs for analysis and calculation.
Applications
Coal water slurry viscosity measurement
Standards
GB/T188564-2008
Steps
1. Install the appropriate rotor using an electric lifting device.
2. Set measurement parameters (such as speed, Measurement mode, etc.) through touch screen or DV data program control analysis software.
3. Place the sample in the measurement position and ensure that the RTD temperature probe contacts the sample to monitor the temperature.
4. Start the measurement, the instrument will automatically run and display the viscosity, shear rate, shear stress, speed, temperature, percentile torque and other data in real time.
5. Save data according to the preset storage method (single point, continuous, regular).
6. After the measurement is completed, the data can be exported through the U disk or network, or further analysis can be carried out using supporting software.
Notice
* When measuring the instrument, make sure that the torque value is between 10% and 90% of the Measurement range to avoid triggering the alarm and ensure the measurement accuracy.
* Allows users to correct the temperature and viscosity correction factor by themselves with reliable and accurate data, but the correction operation is password protected.
* Measurement range of material temperature is 5 ℃ to 75 ℃, please ensure that the sample temperature is within this range when using.
* The viscosity measurement range of the instrument is 100~ 170,000 mPa.s, the shear rate adjustment range is Ds = 11/s~ 1801/s, and the speed adjustment range is 1RPM~ 200RPM, please use it within the specification range.
Measurement accuracy of +/- 2% F. S and reproducibility of ≤ +/- 1% (F. S).
