Electronic Automatic Bilge Pump Switch

Unlike ordinary float switches, the Bilge Sentry, utilizes 100 percent electronic circuitry to sense the presence of bilge waters.

The Bilge Sentry has no moving parts to stick, jam, or fail after extended exposure to harsh bilge environments.

Pump activation is controlled through a stainless steel sense probe located in the bilge compartment. A 5-10 second delay prevents unwanted pump cycling which commonly occurs from the sloshing of bilge waters.

Once activated, your bilge pump will run for approximately 30 seconds, then depending on remaining bilge water levels, the Bilge Sentry will either shut down or continue to operate your bilge pump until water levels have fallen below the sense probe.

The Bilge Sentry's unique design allows great installation flexibility. Now it is easily possible to drain water from the absolute lowest point in your boat. The Bilge Sentry will last for years because the control box is completely encapsulated in epoxy. Only the solid stainless steel probe is mounted in the wet corrosive bilge.
