VA-3000 Series0 pages

VA-3000 Series / VS-3000 Series 06
Wide Variety of Standard Features and Functions as well as Optional Features.
Allow the VA-3000 to be Configured to Meet the Requirements of Any Application.
Standard functions configured prior to shipment include:
Atmospheric Pressure Correction:
Select 0-1VDC or 4-20 mA for each of two channels per module
VA-3000 Series
Other Optional Features:
Output:
Multi-Component Gas Analyzer
The pressure compensation function corrects the output signal from the NDIR
and MPA O2 modules for changes in sensitivity caused by changes in the
atmospheric pressure since the instrument was last calibrated with a cylinder
calibration gas. Galvanic, PMA and Zirconia O2 modules and the CLD module
do not have pressure compensation. This option is useful if you desire the best
possible accuracy over a period of time when you will not calibrate the
instrument with cylinder gas.
Communication Ports:
One of two RS-232 may be changed to RS-485
Automatic Calibration:
Activate this function to allow the instrument to reset the zero and span
calibrations when the instrument is manually or remotely put in the calibrate
mode.
Select Automatic Range Change:
Allows the user to set a point where the analyzer will automatically change
from the measurement range it is currently on to the next highest or lowest
range available in the analyzer module depending on whether the measured
concentration is increasing or decreasing.
Select Negative Display:
Negative measurement value means you will never see any value on the
screen less than 0.000.
Select O2 Correction:
If an O2 module is installed in the instrument case with other modules such as
CO and NOx and if this function is activated, the measured values for CO and
NOx will be corrected for dilution based on the measured O2 concentration in
accordance with US EPA procedures. The instrument will have analog and
digital (if communication options are installed) outputs for both the raw CO and
NOx values as measured and the corrected values.
Select the Concentration HOLD Function:
If this function is activated, when the instrument is put into the zero or span
calibration mode, the concentration values indicated at the analog outputs and
any digital outputs (if additional communications options are installed) will be
held at the concentration value last measured before the instrument mode was
changed.
Set Alarms for the Gas Concentration:
There are two alarm points that can be set for each analyzer module. These
can be set to alarm at a Low (zero) and a High value, or at a High and a Higher
value. The alarm will show on the instrument front panel screen and will
transmit information via the RS-232 port and if the optional PIO board is
installed, contact closures are also available.
Select Memory of Calibration and Alarm History:
The processor in the instrument stores the zero and span calibration
coefficients for each module installed in the case for 15 days. This information
can be displayed on the front panel to indicate if there is a significant trend in
calibration shift that would indicate that there might be a problem with the
analyzer module. The processor also stores the last 30 analyzer alarms that
occurred for each module installed in the case. This information can be
displayed on the front panel.
Rack-Mounted Sample Gas Conditioning Systems
VS-3000 Series
Flow Rate Display:
A miniature mass flow meter is installed to monitor the flow rate of gas through
the instrument. The flow rate is displayed on the front panel and if the flow rate
deviates from a preset value an alarm will be displayed on the front panel and,
if the VA-PIO-01 board or other communication options are installed, will be
transmitted external to the instrument.
Stainless Steel Tubing with Swaglok Fittings
Stainless Steel Tubing and Swaglok Fittings can be provided as an option
when the instrument is initially delivered. This option cannot be easily added
at a later date. This option is not available for the CLD or O2 analyzer modules
at this time.
Separate Gas Inlet Fittings per Module:
In the standard instrument, gas flows to the three modules sequentially in
series. As an option HORIBA can make separate gas inlet connections for each
module with a common exhaust; however, the software is designed so that all
three modules will be in the zero calibration mode simultaneously and this
cannot be changed. The span calibration may be done separately.
Gas Connections on the Front Panel:
The gas connections can be moved from the rear of the case to the front panel
but if this is done then only two analyzer modules will fit into the standard
VA-3000 case.
HORIBA continues contributing
to the preservation of the global
environment through analysis
and measuring technology.
