The BL983317 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 below the set point. The relay can be used to activate a dosing pump to add chemical until the desired set point is reached. Chemicals that can be dosed include nutrient solutions.
The BL983327 is a closely related product that has the same measurement range but has a relay that is activated when the reading is above 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.

Adjustable Dry Contact Dosing Relay
The BL983317 features a dosing relay that is activated when the reading is below a user programmable set point.
Programmable Overdose Protection
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.
Relay Control Override
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
Multicolor LED indicator allows an operator to quickly check the status of the controller.
- Green = Meter in measurement mode and reading is above the set point.
- Orange/Yellow = Reading is below the set point and the relay is active.
- Blinking Red = Indicates an alarm condition such as when the maximum dosing time has been exceeded.
Fuse Protected Dosing Contacts
The relay dosing contact is rated for up to a 2A load and is fuse protected.
Labeled Termination Connections
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.
1/2'' NPT Male Threaded Amperometric Probe for Mounting In-line*
The BL983317 mini controller uses the HI7632 conductivity probe that is available with different cable lengths.
*HI7632 is not included and must be ordered separately
Front View
Installation cut-out dimensions are provided as well as outside panel dimensions.
Side View
Adjustable location brackets allow the controller to slide easily and securely into place.
