Comparison of Density and Density between EX505 Portable Density Pot and Traditional Pycnometer
1. Method Comparison of the traditional pycnometer (pot) to measure the pulp density or concentration is to use a pycnometer (pot) filled with pulp liquid, and then measure the weight through a spring scale or bench scale, and then according to Ï = M / V, manually calculate the pulp density, If you want to know the pulp concentration, you need to check the density and concentration conversion table to get the pulp concentration value.
The portable electronic concentration pot is filled with a standard stainless steel container equipped with a meter filled with pulp liquid, and the pulp density and concentration are then read directly on the meter LCD.
2. Stability Traditional pycnometers are mostly weighed using spring scales or bench scales. Due to the spring's metal memory and fatigue factors, long-term use will result in significant loss of accuracy and poor stability.
The electronic density pot employs a tension sensor, which is a device that converts a physical signal into a measurable electrical signal output, uses two tensile force transmission parts to transmit force, has a force-sensitive device in its structure, and uses alloy steel for the tension transmission part. There is no deformation factor and it can be used for a long period of time with high stability.
3. Accuracy Most of the spring scales or desktop scales used in traditional pycnometer (pot) method are civilian products, the error is generally more than 2%, and the error caused by the difference of gravity acceleration everywhere cannot be corrected.
The electronic density pot uses a tensile force sensor error of about 3/10000. The superposition circuit part AD converts the error. The total error is between 10,000 and 1/10000, and the error caused by the difference in the acceleration of gravity around each place can pass the first calibration. eliminate.
4. Volume, weight and portability Due to the heavy weight and large size of the desktop scale, it is not easy to carry it to the site. In the traditional measurement, the liquid must be brought back from the field to the laboratory for weighing. If a certain period of time is to be measured, Second, it requires personnel to go back and forth between the field and the laboratory for multiple trips, and the density value obtained each time lags behind, real-time performance is not strong.
The electronic density pot has a weight of about 300 grams and a small volume. It is very easy to carry to the site for measurement, and can quickly obtain the current density value. The results can be immediately reported to the higher level by phone or walkie-talkie. The real-time performance is strong.
5. Reading Tables Traditional measurement, it is easy to produce reading errors and manual calculation errors.
The electronic density pot adopts the liquid crystal display, and the reading is directly and conveniently, and its own backlight can ensure that the light is dim, the reading is still accurate, and there is no reading error and calculation error.

6. Auxiliary function The electronic density pot has a CPU and a memory, so it can be easily superimposed on the auxiliary functions. For example, the site slurry is sampled several times. The electronic density pot can store each density value, and automatically calculate the average value, reducing the use of personnel record data. And computing workload and so on.
7. Price Electronic density pot using high-precision sensors, and has a circuit board and CPU, so the cost is higher, in accordance with the accuracy of classification, sales price of 5500 yuan to 9,500 yuan, can consult Beijing Inecoside Technology Co., Ltd.,.
