BL-983315-1 TDS Mini Controller 0.00 to 199.9 mg/L
BL-983315-1
The BL-983315 is a compact, panel mounted, process controller for measuring total dissolved solids (TDS) of a process stream that is within the 0.0 to 199.9 ppm (mg/L) 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 supply power to a dosing pump or a solenoid connected to a valve. The BL-983315 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation.
The BL-983315 uses a 0.5 conversion factor in which 1.0 μS/cm = 0.5 ppm.

Adjustable Dry Contact Dosing Relay
The BL-983315 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.
Multi-colour LED Indicator
Multi-colour 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.
Labelled Termination Connections
Quick-connect terminal blocks are clearly labelled 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" (13mm) NPT Male Threaded Amperometric Probe for Mounting In-line*
The BL-983315 mini controller uses the HI-7634-00 conductivity probe that is available with different cable lengths.
*HI-7634-00 is not included and must be ordered separately.
