Each Model 1401 Oxygen Analyzer System consists of a zirconium oxide fuel sensor mounted in a heavy-duty probe with lengths from 12" to 9 feet (305mm to 2743mm).
The cell is protected by a 5 micron Sintered SS filter and unlike ceramic filters it can not be damaged by temperature or mechanical shock. In addition it can be cleaned and reused!
NEMA 12 enclosure houses the electronics the 1401 is designed to provide accurate, continuous oxygen measurements on a long-term basis with a minimum of maintenance. In the event of a component failure, the probe can be easily disassembled in the field, and the fuel cell sensor, heater, and temperature sensor assembly can be quickly and easily replaced. Costly downtime awaiting factory repairs can be avoided.
Each Model 1401 Oxygen analyzer control NEMA 12 enclosure, 4-20mA output. The 2100 probe standard material is 304 S.S. (316 option available).

How It Works:
The Model 2100 probe extends the cell into the gas stream where the flue gas diffuses to it. The cell is maintained at 815°C and the cell emf is sent to the control unit to be processed and converted to % oxygen.

1401 Standard Features:
-
Pre-Tested - Each system is pre-tested and all gas plumbing is check before shipment. Connections for all gasses are made through NPT connections installed in the enclosure.
-
Reliable - Measurements are made on "wet, total sample basis" using the well known Nernst equation. Zirconium oxide fuel cell measurement of oxygen is currently used in installations worldwide.
-
Stable - The oxygen analyzer is insensitive to changes in process gas flow or temperature and is independent of fuel type.
-
On-Line Calibration - The oxygen sensor cell can operate for months without calibration, however a manual operated calibration gas control system is provided to test the system with certified gases.
-
No Sample Lines - No sample lines to clog, leak, dilute or slow system response time.
-
Low Maintenance - All components, including the detector are easily assessable and can be field serviced without removing the probe or the mounting flange. Long term, continuous operation with a minimum amount of operator intervention.
