Introduction
When the non-pressurized internal pump option is included, the rear-panel zero
outlet port is internally connected to a passive scrubber which functions identically
to those previously described. In operation, the zero outlet is plumbed either
to the analyzer sample intake port or to the zero air intake port, so that analyzer
suction provides flow through the scrubber.
Options
More detailed information found in “Advanced Theory of Operation” on page 22.
Input Configurations
There are six different input plumbing configurations available. The units
may be equipped with or without an internal pump. Units without internal
pumps can be supplied with one or two gas supply inlet ports (carrier and
dilution). Models with pumps are available with gas stream bypasses for either
the dilution or carrier stream or both. (Units without internal pumps do not
require gas stream bypasses.) Those with internal pumps have a single inlet port
supplying the pump, the outlet of which is split into carrier and dilution streams.
The gas stream bypasses on these units are also downstream from the pump,
permitting the user to connect external scrubbers, driers, separate gas supplies,
etc. in either or both streams. All models are available with nominal maximum
flow capacities from 1 to 20 liters per minute.
Rack Mount Options
The standard Dynacalibrator is packaged in a free-standing case with carrying
handles, for bench use. The units may also be packaged for mounting in a
standard 19" equipment rack.
Special Customer Options
Special options, identified by the “S” at the end of the model number, are not
covered in this basic manual. If your Dynacalibrator is equipped with a special
option, the required additional information will be found on the Special Option
Sheets in the back of this manual. The Special Option Sheets carry the serial
number of the Dynacalibrator to which they apply.
Electronic Flow Control
Many of the flow components can be replaced by a mass flow controller for
simplified operation. (Figure 1b)
