Dencytee Arc Total Cell Density Sensors

The in-line optical density sensor employs a blend of transmission and reflection measurements, ensuring consistent reliability across both low- and high-concentration scenarios. By utilizing a guided correlation model, a linear relationship between off-line and in-line measurements is established, guaranteeing precision throughout the process.

This advancement paves the way for enhanced process efficiency and potential automation in the future. While traditional control strategies remain applicable, this innovation also offers the opportunity to chart a fresh course for heightened productivity.
