The Batch Controller RA33 is designed to record flow and control output signals for valves and pumps to ensure the exact dosing of predefined batch quantities. The measured volume can be corrected with the temperature/density compensation function. The filling process can be optimized with an automatic or fixed after-run correction. Mineral oils can be corrected according to the ASTM D1250-04 standard.
Recording and controlling of slow batch operations with a duration of longer than 10 seconds. Typical applications include:
Food industry
Chemical industry
Pharmaceutical industry
Oil & gas industry
Lợi ích
