The Batch Controller RA33 is specifically designed for recording flow and controlling output signals for valves and pumps, ensuring precise dosing of predefined batch quantities. It features a temperature/density compensation function to correct the measured volume, optimizing filling processes with both automatic and fixed after-run corrections. It can accommodate the correction of mineral oils in accordance with the ASTM D1250-04 standard.
Typical Applications Include:
Accurate Results:
Fixed and automatic after-run corrections ensure constant, highly accurate dosing.
Enhanced Quality:
Enables fast and precise dosing to improve product quality.
Volume Correction:
Optional volume correction for mineral oils as per ASTM D1250-04 enhances measurement accuracy.
Detailed Logging:
Comprehensive logging of protocols, including preset counters, volume counters, batch names, numbers, error messages, and changes to operating parameters.
Standard Compatibility:
Compatible with common flow transmitters, temperature sensors, and density sensors.
Remote Control Options:
Capability to start and abort batch runs remotely.
Statistical Analysis:
Provides daily, monthly, and annual statistics on batch run sizes and quantities.
The Batch Controller RA33 functions as a Batch Controller, specifically designed for filling and dosing applications. It adheres to the ASTM D1250-04 calculation standards for precise volume measurement.
