One of the great benefits of the
Apex Mass Flow Controller, Apex Mass Flowmeters and Apex Vacuum Pressure
Controllers is how we can for a low cost provide communications and
control systems through RS 232 connections and a computer.
Recently, one of our customers took
his vacuum tube furnace application to demonstrate how the Apex Products
could be used to control the vacuum and gas flow through his system.
Picture below shows the two Apex
MFC's. They then connect to the BB9 Junction Box. This BB9 Junction Box
can be seen connecting to the computer in Fig 3. The Apex Remote Display
displays pressure from the Apex Vacuum Pressure Controller in Fig 2. Up
to 9 Apex Devices (Mass Flow Controllers, Mass Flow Meters or Vacuum
Pressure Controllers) can be added to this system. Up to 26 can be added
to one addressable RS 232 connection on one computer.
