1.3 Features of the Analyzer
The analyzer provides the following capabilities:
• Rapid response
• 5-14 week tape life (dependent on gas concentration), which is up to 2 times greater than
that of traditional tape analyzers. Optical tape counter ensures exact spacing of stains and
keep track of tape consumption
• Low operation and maintenance costs
• Uninterrupted operation with dual redundant AC and DC power supply
• Ethernet communication and USB port with easy to use Windows
TM
based PC software
• Enhanced data logging allows for up to ten months of data storage for complete audit trail
and trouble shooting and report generation.
• Built-in MODBUS communications / RTU capabilities and a large number of outputs and
inputs with sensor auto-calibration on each analysis and dual redundant power supply.
1.4 System Operating Control
The analyzer is controlled by a dedicated data acquisition system which provides supervisory
control, performs all calculations and provides the user interface.
The system includes an onboard computer system which provides full screen display of the
phosgene concentration, key system control parameters and their status.
A hand held key pad is provided for user interface with the analyzer. Operation of the system
with the keypad is described in Section 4. As an alternative, a PC based Graphical User
Interface (GUI) which can be used to view and enter information on a remote basis is
described in Section 5.
