At Bettersize, our mission is to provide best-in-class particle size measurement units, comprehensive solutions and exceptional customer services. We are dedicated to assist scientists, researchers and engineers around the world to understand material properties, facilitate research, improve production efficiency and beyond.

BT-Online1 Online Particle Size Analyzer is an on-line particle size monitor system for real-time particle size monitoring and control in powder manufacturing industries. Driven by Standard Operation Procedure (SOP), it automatically samples, measures, recovers and processes data directly from the powder delivery pipeline, providing 24-hour particle size detection and control for a variety of dry powder production lines.

1. Real-time Control System
As well as being able to continuously monitor laser particle sizing, the system also has a function for real-time feedback and control. The system will collect real-time size data and perform calculations against the particle size analysis of nanoparticles control limits. It automatically generates the feedback signal to the control center. This closed loop feedback control system will achieve better quality improvement, higher efficiency, reduce wastage and save energy.

2. Automatic Centering Guarantees perfect conditions of the optical system
By moving the laser detector center point to the focus point of the lens before each test, the automatic centering function guarantees perfect conditions of the optical system, therefore providing accurate and repeatable testing results.

3. Accuracy Calibration Maintain accurate datum lifetime
This function maintains operating parameters at consistent conditions, producing consistent and reproducible measurement across the board for all instruments, old and new.

4. Reliable Sampling System
Sample dispersion is achieved by accelerating the powder through a venturi. The "backflush" and tapered pipe design prevents blockage of the sampling tube, and keeps the residual powder clean, ensuring the accuracy and continuity of real-time testing.

5. Versatile Functionality of the System
The system has power interruption protection and over-pressured protection functions. Under these abnormal operating conditions, it will initiate an automatic shutdown sequence to protect the system from harm. The electrical and mechanical system of the BT-online1 has robust interference protections; it is ready for the haphazard nature of a production environment and an electromagnetic interference prone environment.

6. Contamination Prevention Optics System
Using the controlled principle of aerodynamics, we devised the double air-cushion lens protection system. The contamination prevention technology will form an invisible double air shield between the sample stream and the lens, eliminating the optics from contamination from sampling, as well as a dust-prone environment. With this technology, the ultimate goal of a long duration of sustainable operation, providing real-time, continuous online particle size analysis monitoring and control can be realized. Accuracy and continuous monitoring of the production data can be achieved.
