The BB1 is a powerful control box that can support one sensor from the X-series, measuring dissolved oxygen, suspended solids, sludge blankets, pH, ORP, open channel flow or fiber consistency. Weighing less than 3 lbs (1.4 kg), the BB1 is distinguished by a three-button panel used to navigate the intuitive software. The plug & play capabilities of the BB1 ensure an easy installation. Calibration is performed in just a few simple steps. The unit is designed with cutting-edge digital technology and software, making BB1 easily upgradeable in the field and ensuring that the customer has the latest software revisions. The control box comes standard with two 4-20 mA outputs. It also features an expansion slot for two additional mA outputs or digital protocol card for Profibus DP communication. The self-maintenance features of the BB1 further enhance its value in the plant. A built-in heater protects the unit against cold weather conditions.

Relay output in the BB1 can be used for alarm or to provide a pulse for automatic cleaning. Output signals are held constant during cleaning cycle at the value prior to starting of the cleaning cycle.
