| Specifications |
| 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. |
| 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 |
