Two Adjustable Sensitivity Ranges
SFF Series Seal Leakage Relays are designed to monitor the shaft seals of submersible pumps for leakage. These products utilize a flange‑enclosure designed to be dead front‑mounted on an inner door and used with back‑mounted sockets. Everything needed for setup, use and troubleshooting is on the top of the unit: LED status indication and low‑profile sensitivity adjustment knob.
