About Float Switches

Often used in hazardous locations, such as chemical plants, refineries, and grain elevators, these switches have a housing that’s UL listed for environments with flammable gases, combustible dust, and ignitable fibers. It is UL listed for use in Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2 hazardous locations. The housing also meets NEMA 4X for use in washdown environments with splashing water, corrosive liquid, and dust. Install the threaded probe directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature. Set actuation points with the adjustment dial.

Switch with one actuation point has one SPDT (single pole, double throw) relay. The relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Switch with two actuation points has two SPDT (single pole, double throw) relays. Each relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Hazardous Location Wall-Mount Temperature Switches

With Threaded Probe

With Unthreaded Probe

Turn heating equipment on or off in environments with flammable gases, combustible dust, and ignitable fibers, such as chemical plants, refineries, and grain elevators. The switch housing is UL listed for use in Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2 hazardous locations. It also meets NEMA 4X for use in washdown environments with splashing water, corrosive liquid, and dust. Switches have a probe on a cable for remote temperature readings. Set actuation points with the adjustment dial.

Switch with one actuation point has one SPDT (single pole, double throw) relay. The relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed). The probe has 1/2 NPT male threads for installation directly into tanks, pipelines, and other process components. It comes with a bushing that adapts the thread size to 3/4 NPT male.

Switch with two actuation points has two SPDT (single pole, double throw) relays. Each relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

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).
