Process Control(5)

The BL983327 is a compact, panel mounted, process controller for measuring conductivity of a process stream. The device features a large LCD with protective cover. Users may choose from automatic or manual dosing modes. When in automatic mode the dry contact relay is activated when a reading is above the set point. The relay can be used to activate a solenoid valve to open and drain a tank (i.e. boiler bleed and feed) or add freshwater until the desired set point is reached. The BL983317 is a closely related product that has the same measurement range but has a relay that is activated when the reading is below the set point. Multicolor LED Indicator LED changes color based on status. Fire Retardant Casing For additional safety the controllers outer case is made of fire resistant plastic. Splash Resistant Cover A clear plastic cover protects the face panel from dirt and liquids.

The BL983324 is a compact, panel mounted, process controller for measuring total dissolved solids (TDS) of a process stream that is within the 0.0 to 49.9 ppm (mg/L) range. The device features a large LCD with protective cover. Users may choose from automatic or manual dosing modes. When in automatic mode the dry contact relay is activated when a reading is above the set point. The relay can be used to supply power to a dosing pump or a solenoid connected to a valve. The BL983324 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation. *The BL983324 uses a 0.5 conversion factor in which 1.0 µS/cm = 0.5 ppm. Multicolor LED Indicator LED changes color based on status. Fire Retardant Casing For additional safety the controllers outer case is made of fire resistant plastic. Splash Resistant Cover A clear plastic cover protects the face panel from dirt and liquids.
