    Hazardous Location Threaded Temperature Switches

    Image of Product. Front orientation. Temperature Switches. Hazardous Location Threaded Temperature 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.
    1 Actuation Point—Switches with one actuation point have 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).
    2 Actuation Points—Switches with two actuation points have 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).

    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.
    1 Actuation Point—Switches with one actuation point have 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.
    2 Actuation Points—Switches with two actuation points have 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).

    Adjustable-Power Temperature Controllers for Plug-In Heaters

    Image of Product. Front orientation. Contains Inset. Temperature Controllers. Adjustable-Power Temperature Controllers for Plug-In Heaters.
    Regulate the amount of power flowing to your heater with the turn of a dial. Instead of a temperature sensor or input, these controllers work like a dimmer on a light switch. To incorporate them, first plug in the temperature controller, then plug your heater into the socket on the bottom of the controller. These controllers are NEMA rated for use in hazardous, corrosive, dusty, and washdown environments.
