About Float Switches

Install these switches into a threaded connection in your tank wall from outside the tank. They activate process equipment such as pumps or motors when the diesel fuel, hydraulic fluid, or oil level in your tank reaches the float. Choose switches with a metal body for durability in harsh conditions.

Horizontal-Mount Hazardous Location Float Switches for Fuels and Oils

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations. Mount them through a tank wall. All are rated NEMA 4 for protection from washdowns. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

Switches with stainless steel body are more corrosion resistant than switches with brass body.

Hazardous Location Vibration-Monitoring Switches

Get NEMA 4 and IP66 protection from dirt and water. Switch is rated for hazardous locations for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. If vibration or shock exceeds a set activation point, the contacts actuate to either shut down your machine or activate an alarm. Reset the switch with the push of a button. The activation point is adjustable between 0 to 5 gravity units (g) at 0 to 60 Hz.

Speed-Monitoring Switches

Set to a specific speed to detect unwanted machinery slowdown that can cause damage and downtime. Applications include drive trains, power-driven components, and conveyors. Switches are UL listed for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. They have an explosion-proof housing and are also rated NEMA 4X for washdown and corrosion protection.
