B8HLD
- Conductive Liquid Level Controller
- Fixed sensitivity
- SPDT Relay output
- 8-pin, Plug-in
The unit is designed to control the maximum and/or minimum levels of conductive liquids. It works typically in the “Pump Down” mode. With both probes uncovered, the relay remains de-energised. When the liquid rises and reaches the upper probe, the relay energises allowing the controlled pump to run and commence emptying the tank/container. When the liquid reaches the bottom probe, the relay de-energises and pump stops.
