Conductivity Mini Controller (0 – 1999 S/cm) 12VDC – BL983313-0
The BL983313 is a compact, panel mounted, process controller for measuring electrolytic conductivity (EC) of a process stream that is within the 0 to 1999 ?S/cm range. 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 dosing pump or a solenoid that controls a valve.
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 BL983313 features a dosing relay that is activated when the reading is above 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 below the set point.
- Orange/Yellow = Reading is above the set point and the relay is activated.
- 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 BL983313 mini controller uses the HI7634 conductivity probe that is available with different cable lengths.
*HI7634 is not included and must be ordered separately
