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 µS/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.

This compact, panel mounted, process controller is ideal for measuring total dissolved solids (TDS) of a process stream. This controller 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 BL983315 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation.

BL983315

Adjustable Dry Contact Dosing Relay

The BL983315 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.
BL983315

Fuse Protected Dosing Contacts

The relay dosing contact is rated for up to a 2A load and is fuse protected.

BL983315 uses a 0.5 conversion factor in which 1.0 µS/cm = 0.5 ppm.

  • Model available with 4-20 mA galvanic isolated output with external dosing disable contact
  • Large Clear LCD
  • Fire Retardant Casing
  • Splash-Resistant Cover

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.

HI7634

1/2″ NPT Male Threaded Amperometric Probe for Mounting In-line*

The BL983315 mini controller uses the HI7634 conductivity probe that is available with different cable lengths.

*HI7634 is not included and must be ordered separately
