Model 8280 Series Dyna Blenders
| Description |
Model 8280
Modular Dyna- Blender System |
The
8280 Series of Dynamic Gas Blending Systems are used to prepare
accurate mixtures of different gases. This system is dynamic
with respect to flow conditions and has no ability to store gas
for demand usage. These control systems function utilizing the
Matheson 8272/8273 Series Controller Transducers. There are two
basic types of units, consisting of a Modular Dyna-Blender or a
Multichannel Dyna-Blender. |
| Modular
Dyna-Blender Model 8280 |
| Matheson's Modular Dyna-Blender,
when used with an existing mass flowmeter or controller,
accurately blends gases in a dynamic flowing system. Several
units can be utilized to make multiple component mixtures. The
unit requires the presence of an existing mass flowmeter or mass
flow controller for mixing operations, or can be used as a stand
alone controller. |
| The basis of the system
is a mass flow controller transducer which either responds to an
external command signal or can be slaved to another mass
flowmeter, mass flow controller or even another 8280 Dyna-Blender.
This unit can also be used in conjunction with other equipment
interfaced through user supplied circuitry via a 4-20mA signal
(optional) or a 0-5 VDC signal for dynamic flow systems. The
Model 8124 Totalizer is also available and can be used to
compile the total amount of gas used over a period of time,
regardless of varying flow rates. |
| The 8280 control box may
be ordered as a stand alone item, or as part of a system (8280
control box, transducer assembly, and cable - see table for
ordering information). |
| Multichannel
Dyna-Blender Model 8284 |
| Matheson's Multichannel
Dyna-Blender accurately controls the flow rates of four
different gases in a dynamic flowing system. Each of the
individual four channels has individual potentiometers and
control switches. The single display is operated by a four
position switch and reads in percent of range. The unit can
control gas mixtures up to four components in composition, with
user supplied manifolds. |
| The gas flow of the
system can be controlled by the individual controller box, an
external 0-5 VDC or 4-20 mA signal (optional) for remote
operation. Each individual channel requires a mass flow
controller transducer which must be ordered separately. |
