HP1000 Lambda sensor control system
For stable, potentially dirty sampling applications
In applications which are by nature stable, then trim control is best maintained using a lambda sensor. While the resolution of this probe over a wide carbon potential range is not acceptable for accurate control, it can be a robust, cost effective solution for an endothermic generator, where the total range is well within the performance capabilities of the sensor. It doesn’t need a reference/burn-off air supply, and will withstand poor quality gas from badly set up gas/air ratios. Our system includes a ball valve for manual isolation of the sample lines for maintenance, and a 40 micron coalescing filter to protect the sensor assembly and sample lines.
Applications:
Modular Endothermic Generator
- Manifold "sample" lines
- Allow for condensation drip
- Manual "shut-off" valves are suggested
- Sintering/Muffle Furnaces
- No need for high-temperature probes
- Fixed sample lines
- Use natural gas as oxygen "getter"
-
Low-Temperature Applications
- Nitrogen-based low temperature, Miscellaneous protective atmospheres
- % Oxygen in residual combustion gases
Featuring:
- AC20 Single-Loop dewpoint or carbon potential atmosphere controller
- Variable output 12 power supply for lambda probe
- Lambda probe manifold block with moisture drainage port
- Coalescing filter
- Isolating ball valve
- Control via solenoid valve or proportioning valve
- 4-20mA output for retransmission of PV if required
- Process "calibration" available at commissioning with our PGA3500.
