Product Description
Ultrasonic on-line particle size monitor technical specification:

Basic function

Online, real-time simultaneous measurement of slurry particle size, size distribution, and pulp density



Measurement method

Multi-frequency ultrasonic attenuation

Measurement range

Size measurement: the largest particle is not more than 1mm,P80 is for the 295 to 25 micron distribution

Density measurement: percentage density of pulp weight is 4~60%.

Reading refresh time

The minimum interval is less than 1 second

Measurement data output

Each channel provides a density analysis value, following the user habits, scaled by weight or volume percentage

)Calibration method

Particle size and density analysis results(density analysis: dry weighting method; particle size analysis:sieving method) for calibration samples in laboratory are calibrated with attenuation parameters measured by instruments

Correction method

Programmable cycle of automatic standard water measurement provides accurate zero tracking for ultrasonic attenuation measurement, which can make the instrument automatically correct electronic single drift and measurement drift caused by ultrasonic transducer surface deposition; pulp temperature measurement can be used for temperature correction. The above measures ensure high accuracy and long-term stability of density and particle size measurement.

Data connection

Connect the DCS control system through the following ways:

4--20m A electrical isolation simulation current loop(each flow channels 4 ways,12 bit resolution, can be used to transmit density measurement values and three size fraction),connects to the DCS control system through a coated twisted pair instrument cable; the longest is up to 1000 meters. Along with 4-20m a simulation current loop signal for each flow channel, provides a pair of switch signals (one out, one in) as the simple contact signal between the DCS system and the particle size monitor ,the signal can be used as an effective instruction for showing the flow channel measurement data.

RS-485 serial links---particle size, alarm. It supports Modbus RTU protocol point to point connection.

Situated in Dandong, one of the most beautiful border cities in China, Dongfang Measurement & Control Technology Co., Ltd. has become one specialized mine automation company that is largest in China and holds the highest market share as well as an inline industrial detecting instrument research, development and production base with the highest technological content in Asia, one leading enterprise in the Digitalized Mine No. 863 Program during the Twelfth Five-year Plan Period of China as well as one unit specially undertaking the development of important scientific instrument and equipment in the country.
