ATC Diversified SPM-120-AAA-10K Single Channel Seal Failure Alarm - 120 VAC, 470-10K Ohms, +/-10% Adjustable

Call for Price

The ATC Diversified SPM Series single channel seal failure module is a specialized control for monitoring the shaft seal of a submersible pump motor. A leak is detected by sensing the position of a resistive float switch installed in the seal cavity. When the resistance drops below the sensitivity rating, the output relay energizes and the LED illuminates. When the fault condition clears, the output relay resets automatically.
