The 201 Pump Controls series is an 8-pin, plug-in style, seal-leak detector that senses seal failures on submersible pumps. A microcontroller-based relay monitors the shaft seal of the submersible pump motor. A resistive probe is installed in the seal cavity. If water leaks into the pump, the resistance measured by the probe decreases. When the resistance drops below the sensitivity setpoint, the unit will trip, and the relay contacts will change state. The unit will automatically reset when a fault is cleared.
