HP2000 Self-Heated Gold Probe
There are certain applications where an in situ oxygen probe is impractical. For those applications, Super Systems Inc. recommends the HP2000 self-heated oxygen probe. This system supplies the temperature required to make an oxygen probe function. For some applications such as a multi-tube generator, or a rotary retort furnace, this probe will allow you to extract a continuous sample of the atmosphere stream and pass it by a standard oxygen probe.
Applications:
- Rotary Furnaces
- Sample line extended into furnace beyond quench chute
- Opposite-end from atmosphere introduction
- Adequate filter system
- Conservative addition of enriching gas
- Modular Endothermic Generator
- Manifold “sample” lines
- Allow for conservation 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

Redundant Probe System
SSi’s Model 9120 Redundant Probe System (RPS) includes:
The Model 9120,- A 24 VDC power supply,
- Two – 24 VDC relays are mounted and wired on a piece of DIN rail for easy mounting by the customer,
- The 2-line operator interface, and
- The cable connecting the operator interface to the Model 9120-RPS.
The two (2) SSi Gold Probes shown in the picture MUST BE ordered separately
Function:
The Model 9120-RPS reads the signal from two oxygen probes located in the same furnace automatically switching the output from the Model 9120 RPS to the probe with the highest millivolt output. It sends that probe’s output to the existing carbon controller to control the enriching gas being added to the furnace.
The probe millivolt “deviation band” and the “alarm delay” time is set using the operator interface. When connected per the electrical drawing, the Model 9120-RPS selects the probe with the highest millivolt output and sends that signal to the controller. As time passes and the other probes millivolt output becomes greater (dependent on the deviation band), the Model 9110 RPS will switch the output from one probe to the other and send the “new” higher millivolt signal to the carbon controller.
The ” asterisks (*) ” on the operator interface display indicates which probe’s millivolts is being used by the furnace atmosphere controller. When the Model 9120-RPS switches the output from one probe to the other it indicates a “deviation band” alarm condition, flashing an “A” on the operator interface. The “A” continues to flash until the probe’s output is back within the “deviation band”.
The operator can manually select the probe that he wishes to be used in the carbon calculation. If this feature is used the 9120 RPS will use the operator selected probe, and NOT switch from one probe to the other automatically.
