Mass Flow Controller Box Model 8274 |
 |
This unit allows the
independent monitoring of up to four mass flow controllers in
use. The system continuously and simultaneously adjusts to
maintain the preset point for each gas flow rate. The individual
setpoint and flow rates can be indicated on the digital readout
by positioning the selector switch to the desired controller.
The control box includes dedicated power supplies for each
transducer, an eight position (four read and four set) selector
switch, a 0 to 100% of range digital display (only one channel
can be read at a time), individual override control valve
switches, flow potentiometers for setting flow rate, a power
cord and four individual cables for the controllers. Also
standard are high and low alarm setpoints selected by the user. |
| It is not
necessary to employ all four stations on the initial system.
Positions may be reserved for future expansion of the system.
Each individual channel requires a Model 8272 or 8273 Series
controller transducer, which must be ordered separately. |
