Sentinel-FCP^TM Extractive Carbon Controller
The Next Generation in Carbon Control Systems

See a video of the Sentinel-FCP!

(Requires Windows Media Player)

Introducing the Sentinel-FCP from Marathon Sensors Inc. - Marathon's acclaimed Extractive Sentinel Technology applied to carbon control.

Finally a real (not approximate like the other guys) carbon control system that can handle non-conventional furnaces!

Includes Carbon/Dewpoint/O2 Controller

Not just a "probe in a box with a reheat well" kludge

Most extractive solutions require you to control using dewpoint, or a "carbon potential" that doesn't use the furnace temperature (i.e. a rough approximation at best - since when can you calculate carbon potential without the furnace temperature!?).

The Sentinel-FCP is 100% carbon control for furnaces where in-situ probes just don't work and where "probe in a box" solutions just aren't acceptable owing to their high cost, high maintenance and poor accuracy.

Now you can control your shaker, rotary or 2200+ F processes with simple, cost-effective Sentinel Technology.

• 10X faster response than conventional probes

• Up to 100X faster than "probe in a box" reheat wells

• Low sample gas volume provides maximum safety

• No heater controller needed

• No separate heater to break down

• No modifications to your furnace - just connect 1/4" plumbing

• Lowest sensor replacement cost

• Simplest set-up and calibration available

• No hidden "maintenance kit," calibration or service costs

• No costly extras like burn-off, reference air or timers needed
