TDS Mini Controller (0.00 to 10.00 ppt) - BL983318

$165.00

The BL983318 is a compact, panel mounted, process controller for measuring total dissolved solids (TDS) 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 above the set point. The relay can be used to activate a solenoid valve to open and drain a tank (i.e. boiler bleed and feed) or add freshwater until the desired set point is reached. The BL983318 uses a 0.5 conversion factor in which 1.00 mS/cm = 0.50 ppt. The BL983318 can measure TDS from 0.00 to 10.00 ppt (g/L)

BL983318

Adjustable Dry Contact Dosing Relay

The BL983318 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 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.

HI7632

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

The BL983318 mini controller uses the HI7632 conductivity probe that is available with different cable lengths.

*HI7632 is not included and must be ordered separately
