Washdown Wall-Mount Temperature Switches
 |
With Unthreaded Stainless Steel Probe |
To protect these switches from splashing water, corrosive liquid, and dust, the housing meets NEMA 4X for washdown conditions. Switches turn heating equipment on or off at a specified temperature. All have a probe on a cable for remote temperature readings. Set actuation points with the adjustment dial.
SPDT—SPDT (Single pole, double throw) switches can be set to turn circuits from off to on (normally open) or from on to off (normally closed). 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. 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 washdown environments. To withstand splashing water, corrosive liquid, and dust, these switches have a housing that meets NEMA 4X. The threaded probe installs directly into tanks, pipelines, and other process components. Use the adjustment dial to set actuation points.
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).

SPDT—Controllers that are SPDT (single pole, double throw) can turn one circuit from off to on (normally open) or on to off (normally closed).
SPST-NO—Controllers that are SPST-NO (single pole, single throw) can turn one circuit from off to on (normally open).
Remote Reset—Remote-reset controllers are best for hard-to-reach locations. To operate, you’ll need to wire the remote reset input terminals, and the sensor must be below the set temperature.
