How about a bilge pump switch that does not activate when oil is present (green product), can be placed at any predetermined level in your bilge, and is small enough to not overcrowd your bilge? The Water Smart® Bilge Pump Switch, a largely popular item among boaters, touches on all three of those sweet spots. The water smart pump switch uses the same fail safe technology as the advanced Oil Smart Switch. But with one sensor and a time delay of eight (8) seconds, even though oil will not activate the switch. If water is present, the switch will eliminate the water and run for an additional eight (8) seconds pumping anything that might be floating on its surface.

Overview and Options

• Incorporates one level sense point, pump on and pump off, an eight (7-9) second time delay allowing for maximum water elimination as well as the elimination of pump cycling for prolonged pump life
• Solid state circuitry - no relay or moving parts
• Defined trip point-Oil/fuel spills will not activate pump
• Performance is not hampered by accumulated oil and grease
• Extended sensor allows the switch to be mounted high above the contaminated water
• All materials are impervious to substances common to boat bilges

Operation

• Sensing is accomplished by measuring the dielectric constant of the medium at the sensor The circuit works as follows: When the water level reaches the sensor the pump will turn on and continue pumping for eight (8) seconds after the water is no longer detected, this operation allows for maximum water elimination and virtually eliminates pump cycling due to water splashing when boat is moving.

Certifications

• UL 508 Marine Listed "Electrical Industrial Control Equipment" and NFPA 302
