The Model 4092-I Isolated Dual Seal Failure Detector is designed specifically for monitoring the shaft seals of two submersible pumps. All electrical inputs are totally isolated from each other.

The probes are to be installed in the seal cavities of each of the pumps. The sensitivity is field adjustable. When a seal begins to leak, contaminating fluid enters the seal cavity, lowering the resistance between the probe and the common connection. If the resistance drops below the sensitivity set-point, the corresponding relay and the LED indicator are activated. The Model 4092-I will automatically reset when the fault condition is corrected.
