The VB5 Sensor from Aqualabo is a high‑precision optical probe designed for sludge blanket level and interface monitoring in water treatment and environmental applications. Using infrared absorptiometry technology, this sensor accurately measures light transmittance through a sludge layer from 0 % to 100 %, enabling reliable control of sedimentation and clarification processes.
This digital probe is suitable for both portable and fixed online installations, and its robust, low‑energy design ensures dependable performance in demanding conditions. With Modbus RS‑485 or SDI‑12 communication, the VB5 integrates easily with dataloggers, SCADA systems, and automated monitoring networks for real‑time data acquisition and process insight.
The VB5 requires no consumables, and only minimal maintenance (keeping optical windows clean) to maintain measurement accuracy. Its compact, rugged build makes it ideal for wastewater treatment plants, clarifiers, sludge tanks, and other civil or industrial settings where precise sludge blanket control is essential.
