Ametek Model CG1100 Oxygen O2 Analyzer Overview
The Ametek Model CG1100 Oxygen O2 Analyzer is easy to Integrate into your host controller and data acquisition system: The CG1100 is equipped with an RS-232 and two RS-485 ports: It comes with configurator software for initial setup of operating parameters and accepts user-provided software for efficient integration with a host controller, or Dycor System 2000 software to record and process data.
Fast Response over a Wide Operating Range: Your system will respond rapidly over an operating range of 0.1 ppm to 100% oxygen.
Integral Mass Flow Meter: Reads sample and calibration gas flow.
Optional System 2000 Software Available: Provides enhanced interface and process monitoring with graphical user interface for Windows 95/98/2000/NT/XP format.
Zirconium Oxide Sensor: Your system will not fail to zero oxygen reading. It is always protected; something not possible with other sensor technologies.
Compact: 8″ x 8″ x 8″ cube houses all electronics, RS-232 port (2) RS-485 ports, I/O port and analog output (4-to-20 mA) isolated.
Optional Vacuum Generator: (Aspirator) – Uses plant air to pull the sample through the sensor eliminating the need for a sample pump.
Ametek Model CG1100 Oxygen O2 Analyzer Applications
- Oven/furnace atmosphere
- Blanket/purge gases
- Welding gases
- Food packaging
- Component aging chambers
- Carbon dioxide purity
- Nitrogen purity
| Sensor Type | Zirconia |
| Operating Range | 0.1 ppm O2 to 100% O2 |
| Accuracy | ± 2% of reading or .05% O2 absolute (0.5 ppm O2 absolute for ppm range), whichever is greater. |
| Response Time | Less than 5 seconds at 150 sccm over one decade. |
| Repeatability | ± 0.5% of reading or 0.1% O2 absolute (0.1 ppm O2 absolute for ppm range), whichever is greater. |
| Maximum Inlet Temperature | 160°F (70°C) |
| Environment | For Indoor Use Only |
| Ambient Temperatures | 0°C to 40°C (32°F to 104°F) |
| IEC Installation Category II | IEC Pollution Degree 2 |
| Maximum Altitude | 2000 meters |
| Relative Humidity | 10% to 90%, non-condensing |
| Sample Flow | 50 to 200 sccm according to user application requirements. The flow rate is factory calibrated at 150 sccm. An integral mass flow meter is used to read sample and calibration gas flow. |
| Maximum Inlet Pressure | 600 to 1795 Torr. Absolute maximum allowable inlet pressure is 1795 Torr (20 PSIA). |
| Minimum Inlet/Outlet Pressure | A higher flow rate will result in faster response and requires higher pressure differential between inlet and outlet pressure. A lower flow rate will result in a slower response and require a lower pressure differential. |
Ametek Model CG1100 Oxygen O2 Analyzer Calibration Gases | |
| Zero Gas | From 0.1 ppm to 10% O2, balance N2. |
| Span Gas | At least one decade above zero gas (10 times greater) recommended. |
| Indicators | LEDs for status of power, communications, and fault conditions. |
| Software | Configurator software to configure and calibrate the analyzer. Runs on a PC with Windows XP or Vista with an RS-232 serial port. Communicates with a single analyzer using either an RS-232 cable or multiple units over an RS-485 network. |
| Communications | Optically isolated RS-232 (one DB- 9F connector) and RS-485 (two DB- 9F connectors). RS-232 selected if RTS signal is set. Multiple units can be networked on an RS-485 network. RS-485 node address is set via externally accessible selector switch. Baud rate is software selectable to 9600 or 19200 baud. |
| I/O | DB-15F connector. Software configurable alarm for oxygen. Two additional outputs for System Fault and Watchdog alarms. Optically isolated analog output, 4-20 MA (optionally 0-5V, 0-10V) for oxygen. |
| Power Requirements | 24VDC ±5%, 2.5A, less than 100 mv noise or ripple. An optional external 24V power supply is available with 100-250 VAC, 47-63 Hz input (AMETEK PN: 25446JE). When using an external power supply, a power connector plug (AMETEK # 19675JE) is required. |
| Enclosure | 8”H x 8”W x 8”D. Powder coat black finish. A clearance of at least 1/4” is required on sides and bottom of unit for air circulation. |
| CE Compliance | EN61326 EMC Directive and EN61010-1 Low Voltage Directive UL Classified and c-UL Classified |
