BL983315 • BL983319 BL983321 • BL983329 TDS Mini Controllers • Models available with 4-20 mA galvanic isolated output with external dosing disable contact • Large Clear LCD • Fire Retardant Casing • Splash-Resistant Cover These compact, panel mounted, process controllers are for measuring total dissolved solids (TDS) of a process stream. The controllers feature a large LCD with protective cover. Users may choose from automatic or manual dosing modes. BL983315: 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 BL983315 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation. BL983315 uses a 0.5 conversion factor in which 1.0 μS/cm = 0.5 ppm. BL983319: When in automatic mode, the dry contact relay is activated when a reading is below the set point. The relay can be used to supply power to a dosing pump to add fertilizer to a nutrient solution in order to maintain an ideal concentration. BL983319 uses a 0.65 conversion factor in which 100 μS/cm = 65 ppm. BL983321: 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 that switches from one DI (deionized) tank to another or to open a valve that will allow lower TDS water to flow into a tank being monitored in order to lower its TDS. The BL983321 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation. BL983321 uses a 0.5 conversion factor in which 1.00 μS/cm = 0.50 ppm. BL983329: 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. BL983329 uses a 0.5 conversion factor in which 100 μS/cm = 50 ppm.
