*DESCRIPTION OF FUNCTION
SFP Series Pump Seal Failure Relays are designed to monitor the shaft seals of submersible pumps. A resistive-measuring probe is
installed in the pump seal cavity. If the seal starts to leak, contaminating fluid enters the seal cavity, which lowers the resistance
between the internal probe & the common connection. When the resistance drops below the user-adjustable sensitivity set-point
of the relay, the output relay energizes & the LED turns ON. The relay output can be used to give an alarm indication of a leaking
seal. These products will automatically reset when the fault condition clears.
