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
Benefits
Fixed and automatic after-run correction for constant, extremely accurate results
Higher quality through fast and exact dosing
Optional volume correction for mineral oils as per ASTM D1250-04
Detailed logging of protocols (preset counter, volume counter, batch name and number) as well as error messages and changes of operating parameters
Standard models are suitable for connecting and supplying all common flow transmitters, temperature sensors and density sensors
Remote control option to start and abort batch runs
Daily, monthly and annual statistics on the batch run size and quantity
