Understand how float switches trigger circuits and when a relay is required.
Vertical-Mount Compressed-Air Float Switches for Fuels and Oils
 |
Mount these switches through the top of your tank. They actuate with a compressed air valve instead of an electrical signal. The air valve opens when diesel fuel, hydraulic fluid, oil, or water moves the float.

Horizontal-Mount Compressed-Air Float Switches for Fuels and Oils
 |
Install these switches through a tank wall. They actuate with a compressed air valve instead of an electrical signal. Use them with diesel fuel, hydraulic fluid, oil, and water.
Fail-Open Valve—For switches with a fail-open valve starting position, the air valve closes when liquids move the float.
Fail-Closed Valve—For switches with a fail-closed valve starting position, the air valve opens when liquids move the float.
