Features

Compact Footprint

Because of its compact design, the 1579 may be used in space saving gas panel systems. The electrical connections are made with D-Sub connectors for both Analog and Profibus versions, in conformance with all CE regulations. While MFC applications in research and development typically use local analog power supply/readouts, many industrial applications are moving to digital bus-compatible communications and power distribution. The 1579 meets both of these requirements.

Profibus DP Communications

In 1997, MKS Instruments was the first manufacturer to develop a Profibus standard for Mass Flow Controllers with the 1179A. The 1579 follows this standard with respect to both the interface and the communications. Further advances in digital electronics and flow design have allowed the development of a coordinated product line using digital processing with both analog and digital interfaces ranging from a minimum of flow rate of 0.2 sccm in the 1179B to a maximum of 300 slm in the 1579.
