The quality of asphalt largely depends on the precise dosing of its components. Accurate level and point level measurement is particularly crucial during the weighing process to ensure a consistent mixture. This is where robust sensors come into play, reliably operating even under extreme conditions.
During the weighing and mixing process, sensors are exposed to high temperatures, dust, abrasive materials, and chemical influences. Additionally, confined installation spaces and fluctuating material properties present common challenges. A durable, low-maintenance technology is therefore essential to minimise downtime and ensure a stable process.
Precise Measurement and Dosing in the Mixing Process
While the capacitive RFnivo® sensor provides a robust and adaptable solution for demanding point level measurement in asphalt production, the NivoRadar® – NR 8 ensures continuous and reliable level measurement in viscous bitumen. Even under extreme conditions such as high temperatures, build-up, and condensation, it delivers precise measurement results.
