MKS® GM100A Digital Mass Flow Controller
Multi-gas, multi-range, metal sealed, digital mass flow controller for rates up to 100 slm
The GM100A digitally-controlled mass flow controller is available with either analog (0 to 5 VDC or 4 to 20 mA) or RS485, Profibus™, EtherCAT®, or DeviceNet™ I/O. The digital control electronics utilize the latest MKS control algorithms for fast and repeatable response to setpoint throughout the device control range. Typical response times are on the order of 500 milliseconds. Digital calibration yields 1% of setpoint accuracy on the calibration gas.
A standard 3-inch footprint enables its use without modifying existing gas line configurations. The GM100A mass flow controller has an electropolished surface finish.
Features & Benefits
- Patented thermal sensor design for exceptional zero stability
- Percent of setpoint accuracy enables precise process control
- Embedded user interface - easily change device range & user gas, monitor & measure performance
