SLA5800 Series digital mass flow controllers and meters deliver precise, repeatable gas flow measurement and control across a wide range of industrial and life sciences applications. Combining high accuracy, exceptional long-term stability and flexible configuration options, the SLA5800 supports reliable process performance in demanding operating conditions.
With a broad range of flow rates, pressure ratings and digital communication options, the SLA5800 provides a versatile platform for applications ranging from bioprocessing and analytical instrumentation to chemical processing and fuel cell testing. Its modular design, multi-gas capability and advanced diagnostics help simplify system integration, reduce maintenance and maximize uptime.
Optimize your bioprocessing application with SLA Biotech Options Packages designed specifically to improve bioprocessing performance.
Features & Benefits
- High Accuracy and Repeatability: Flow accuracy up to ±0.6% of set point and ±0.2% repeatability provide precise, consistent gas delivery for critical processes.
- Exceptional Long-Term Zero Stability: Zero drift of less than 0.2% of full scale per year helps maintain process consistency while reducing recalibration requirements and total cost of ownership.
- Wide Flow and Pressure Range: Flow rates from 0.003 to 2500 slpm and pressure ratings up to 1500 psi (optional 4500 psi) accommodate a broad range of operating requirements.
- Programmable Multi-Gas/Multi-Range Capability: Store up to six gas calibrations in a single device, simplifying gas changes, reducing inventory and increasing application flexibility.
- Flexible Communication Options: Native EtherNet/IP™, PROFINET, EtherCAT®, DeviceNet™, PROFIBUS, RS485 and analog communication options for easy integration with new and existing control systems.
- Advanced Diagnostics and Alarms: Built-in diagnostics, configurable alarms and an independent service port simplify troubleshooting and support maximum system uptime.
- Easy Configuration and Servicing: An embedded web-based interface on EtherNet/IP™ and PROFINET configurations simplifies setup, monitoring and troubleshooting. Brooks Expert Support Tool (BEST) software provides additional servicing capabilities, including valve tuning and calibration with a license key.
