Functional engineering application
The BLX-LC-1100 Multi-Probe Liquid Level Controller provides reliable, maintenance-free automatic level management for borehole water storage tanks, overhead commercial reservoirs, wastewater sumps, and industrial boilers in Kenya. Operating on the conductive liquid sensing principle, the controller detects liquid presence across three stainless steel electrode probes: Common (Ground), Low (Start/Stop threshold), and High (Stop/Start threshold). A front-panel rotary potentiometer adjusts sensing sensitivity from 5kΩ to 100kΩ, ensuring reliable detection across varied water types from pure mountain runoff to borehole mineral water and treated sewage effluent. To prevent galvanic corrosion and electrochemical scaling of the immersed probes, the sensing circuit energizes the electrodes with an isolated, ultra-low AC voltage (8V AC), ensuring years of trouble-free probe life.
DIN-rail mount conductive liquid level controller relay for 3 stainless probes, featuring adjustable sensitivity (5k-100kΩ), 8A SPDT output, low 8VAC probe voltage, and pump filling/emptying modes.

Common questions on this part
The BLX-LC-1100 provides both Normally Open (NO) and Normally Closed (NC) relay contacts. Connecting the pump contactor through the NC terminal configures filling mode (pump runs when tank is below Low probe and stops at High probe). Connecting through the NO terminal configures emptying mode.
Standard 316 stainless steel electrode rods with ceramic holders (such as the STARNEX STX-PRB-SS316) are suspended at the desired depths in the tank via single-core insulated cable.
Yes. Install two probes above the pump motor intake in the borehole; when the water table falls below the low probe, the controller de-energizes the pump starter to prevent dry running damage.
No. Conductive level controllers require conductive liquids (water, milk, wastewater, chemical solutions). Pure oils and diesel are non-conductive and require float switches or hydrostatic pressure sensors.
Yes. Level controllers and stainless steel probe sets are available off-the-shelf at STARNEX in Nairobi.
