The MPR E-Scan online concentration analyzer for potassium hydroxide plant brine analyzer is a microcomputer processor driven online brine concentration analyzer. Due to its split design, the CPU and main circuit board of the instrument are separated from the optical part, making the system more resistant to high temperature and vibration, better stability, more accurate testing, and longer effective service life. It can display the concentration value of the product in real time and transmit it to the system for easy system integration and control.
The MPR E-Scan online saltwater analyzer can be applied to monitor and control the concentration of saltwater in potassium hydroxide plants. The following is its related introduction:
working principleBased on critical angle total reflection measurement technology. The light from the LED passes through the prism and undergoes reflection and refraction at the interface between the prism and the saline solution. When the incident angle of the light is greater than the critical angle, the light refracts into the solution, while the light below the critical angle is reflected back to the prism and received by the CCD sensor above the prism. Due to the different refractive indices of saline solutions of different concentrations, the critical angle also changes accordingly. The CCD sensor calculates the concentration value of the saline solution through a microprocessor based on the changes in the brightness and darkness of the received light.
Technical SpecificationsThe measurement range is generally 0.0-350.0g/L, with a resolution of ± 1g/L, a temperature resolution of 0.1 ℃, a working temperature range of -20-150 ℃, a pressure bearing capacity of 2MPa, a protection level of NEMA 4X (IP65), an output signal of 4-20mA, and a concentration measurement accuracy of ± 0.1%.
Instrument FeaturesAdopting a split design, the instrument CPU and main circuit board are separated from the optical part, making the system more resistant to high temperatures and vibrations, improving stability, testing accuracy, and effective service life. At the same time, the analyzer has factory calibration and automatic temperature compensation functions, which can be directly put into use without on-site calibration, improving the convenience of installation and use.
Installation methodThreaded or flange connections can be selected based on the actual pipeline situation, and the sensor can be installed in a suitable position on the saltwater pipeline to ensure that saltwater can flow fully and stably through the sensor measurement area, in order to obtain accurate concentration data. At the same time, an online mechanical brush automatic cleaning device can be equipped to prevent impurities from coating the window inside the pipeline, ensuring measurement accuracy.
Application in Potassium Hydroxide PlantIn the production process of potassium hydroxide, saltwater is an important raw material, and its stable concentration is crucial for subsequent production processes. The MPR E-Scan online saltwater analyzer can be installed at the overflow of the desalination tank or on the saltwater transport pipeline to monitor the saltwater concentration in real time. When the concentration is abnormal, the data can be transmitted to the control system in a timely manner, so that operators can take corresponding measures to ensure that the saltwater concentration is stable within the process requirements, providing a guarantee for the stable production of potassium hydroxide.
