SPM Series Single Channel Seal Failure Alarm
The SPM Series Single Channel Seal Failure Alarm 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.
