The BL983319 is a compact, panel mounted, process controller for measuring total dissolved solids (TDS) in a process stream that is within the 0 to 1999 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 below the set point. The relay can be used to supply power to a dosing pump to add fertilizer to a nutrient solution in order to maintain an ideal concentration.*The BL983319 uses a 0.65 conversion factor in which 100 ?S/cm = 65 ppm.?
LED changes color based on status.
For additional safety the controllers outer case is made of fire resistant plastic.
A clear plastic cover protects the face panel from dirt and liquids.
The BL983319 features a dosing relay that is activated when the reading is below a user programmable set point.
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.
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 allows an operator to quickly check the status of the controller.
The relay dosing contact is rated for up to a 2A load and is fuse protected.
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.
The BL983319 mini controller uses the HI7634 conductivity probe that is available with different cable lengths.
