Home Products Mass Flow Controllers Elastomer Sealed 4800 Series

4800 Series Elastomer Sealed Thermal Mass Flow Controllers & Meters

Ultra-fast response for time-critical flow processes.
Models 4850 / 4860

The faster your thermal mass flow controllers and meters respond, the more efficient and productive your processes can be. That’s the key advantage of the 4800 Series controllers and meters: An advanced MEMS-based thermal sensor, combined with a proprietary PID algorithm to optimize control valve response, makes it possible for select 4800 Series controllers to quickly match actual mass flow to any changes in set point. The optional Local Operator Interface (LOI) provides a convenient user interface to view, control, and configure the devices eliminating the need for remote secondary electronics.

4800 Series Data Sheet

Features

  • Flow response time (settling time) <0.75 seconds
  • Innovative MEMS sensor and proprietary PID algorithm
  • Compact size is less than half the size of typical thermal MFCs: 1” x 3” x 4” (25 mm x 76 mm x 101 mm)
  • Optional Local Operator Interface (LOI) simplifies set-up and operation; free LabVIEW VI download for monitoring and zeroing the device
  • Digital capability via RS-232

Benefits

  • Well suited for wide range of common, non-corrosive gases
  • Fast response time ensures rapid steps during process recipe changes
  • Excellent for OEMs: Compact size eases integration into tight machine spaces and speeds installation
  • Optional Local Operator Interface (LOI) is a turnkey solution for local indication, set point control and device configuration; eliminates need for remote secondary electronics
  • Variety of communication options makes it easy to align with user requirements

Applications

  • Heat treating, cutting/welding and other thermal processes
  • Solar/thin film physical vapor deposition (PVD) systems
  • Analytical devices to measure and control reagent, calibration and sample gas flows
