The Sentinel-FCP extractive carbon control package delivers carbon measurement for optimal control of heat-treating processes. It pairs an extractive lambda probe with the company's dual-loop process controller to optimize combustion. The lambda probe, capable of oxygen sensing from parts-per-million of up to 15% oxygen, draws a sample from the furnace and provides an oxygen measure to the controller. The Dual Pro uses this input and the furnace temperature to calculate the furnace atmosphere carbon levels and dew point. The unit can then automatically adjust the trim gas and furnace temperature. The probe is not susceptible to damage caused by vibration and thermal shock, extended probe life and lowering maintenance costs.
