460-15-100-SLD

SymCom 460-15-100-SLD is a seal-leak detector to sense seal failures on submersible pumps. Littelfuse microcontroller-based relay monitors the shaft seal of a 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. Output relay logic can be reversed by removing an external jumper. SymCom unit will automatically reset when a fault is cleared. In submersible pump applications, early indication of seal failure is critical to allow maintenance of the pump before additional damage occurs. SymCom seal leak and leak/temp relays provide protection against seal leaks and over-temperature by monitoring sensors within the pumps and providing early warning or disabling the pumps.
