The BL983320 is a compact, panel mounted, process controller for measuring electrolytic conductivity (EC) of a process stream that is within the 0.0 to 199.9 μS/cm 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 activate a solenoid that switches from one DI (deionized) tank to another or to open a valve that will allow lower EC water to flow into a tank being monitored in order to lower its EC. The BL983320 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation.
LED changes color based on status.
For additional safety the controllers outer case is made of fire resistant plastic.
A clear plastic cover protects the face panel from dirt and liquids.

BL983320's 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 EC water to flow into a tank being monitored in order to lower its EC. The BL983320 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation.
The BL983320 features a dosing relay that is activated when the reading is above a user programmable set point.
For enhanced safety the mini controller can be programmed to deactivate the dosing relay if the set point is not reached within a specified time interval. The overdosing timer is programmable from 5 to 30 minutes or disabled.
With the flick of a switch the mini controller's relay can be disabled (Off), placed in control (Auto), or be activated for manual operation (On) which is useful for priming a dosing pump.
Multicolor LED indicator allows an operator to quickly check the status of the controller.
The relay dosing contact is rated for up to a 2A load and is fuse protected.
Quick-connect terminal blocks are clearly labeled for easy connection to power, conductivity probe and relay that can be used to operate a dosing pump, valve, audible alarm, or light.
The BL983320 mini controller uses the HI7634 conductivity probe that is available with different cable lengths.
