In this short but vital extract from the Aillio Bullet Masterclass, we deep dive into the technology that makes the Bullet roaster one of the most precise home/prosumer machines available: its innovative sensors!Understanding these sensors is key to unlocking consistent, professional-grade roast profiles.We break down the three main sensors, explaining exactly what they measure and how to use them for more consistent results:1. Bean Temperature (BT) ProbeThe classic probe, measuring temperature *in between* the beans. Useful for comparing against traditional roasters.2. Infrared Bean Temperature Sensor (IBTS)This game-changer measures the surface temperature of the bean (or the drum during pre-heat) for ultra-fast, precise, and volume-independent readings. Learn why the IBTS is the sensor you should be relying on.3. Pressure Sensor (FlowSense)Available on the R2 and R2 Pro models, FlowSense ensures a perfectly steady airflow by automatically compensating for chaff buildup. This makes your roast profiles more repeatable and reliable than ever.------------------------------------------------------MASTER THE AILLIO BULLETWant to master every function, technical detail, and maintenance step of your Aillio Bullet?
