Features

Wide Choice of Digital and Analog Interfaces

The GE50A digitally controlled MFC is available with either analog or digital I/O. The digital control electronics utilize the latest in MKS control algorithms providing fast and repeatable response to set point throughout the device control range. Typical response times are on the order of 500 milliseconds. The GE50A’s analog and digital I/O can easily be used to replace those same I/O types of the 1179A MFCs. All GE50As include Modbus as an available secondary I/O (excludes PROFINET® and EtherCAT®).

Standard 3 inch Footprint

The GE50A utilizes the standard 3-inch footprint most often used by MFCs in the 5 sccm to 50 slm flow rate range enabling its use without the need to modify existing gas line configurations.

All Metal Wetted Surfaces

The design of the GE50A incorporates a minimal use of elastomers. There is only one external elastomer seal and elastomer valve plug. Otherwise, all wetted surfaces are of metal. The GE50A comes standard with Viton® seals along with options for Buna, Neoprene®, EPMD or Kalrez® allowing for the device’s use with gases requiring one of these alternatives

Percent of Setpoint Accuracy

Included digital calibration yields 1% of set point accuracy with N2 calibration gas for 20 to 100% of the full scale flow range.  Set point accuracy enables precise process control vs accuracy stated relative to full scale.  For mass flow rates of 2 to 20% full scale the accuracy is ±0.2% of full scale.

Embedded User Interface

An embedded user interface provides the ability to easily change device range and user gas which reduces inventory requirements. You can also monitor MFC functionality and collect performance data in-situ.

Patented Thermal Sensor

A well proven, patented thermal sensor design provides exceptional zero stability. US Patent No 5461913.
