Fixed-Setpoint Threaded Temperature Switches

Set to actuate at a specific temperature, these switches are easy to setup and prevent changes to the setpoint. They have a threaded probe, so they install directly into tanks, pipelines, and other process components to turn equipment on and off at a set temperature. All switches are NEMA 4 and 13 rated to seal out dirt, oil, and water from washdowns.

Narrow Differential Range Sensitivity—Narrow differential switches reset after a small temperature change in the opposite direction of your switch's actuation. For example, in a rising-actuation switch, they reset after the temperature falls 3° below the setpoint. Use them in systems where temperature changes slowly and where you need precision.

Wide Differential Range Sensitivity—Wide differential switches reset after the temperature significantly decreases (approximately 15%) below the setpoint. Use them in systems that cannot handle frequent power cycling.

Rising Actuation—Rising actuation switches activate when the temperature rises to the setpoint and then reset when the temperature falls below the setpoint. Choose rising actuation SPST-NO switches to power a cooler or trigger an alarm. Choose rising actuation SPST-NC switches to turn off a heater or other equipment when the temperature rises to the setpoint.

Falling Actuation—Falling actuation switches activate when the temperature falls to the setpoint and then reset when the temperature rises above the setpoint. Choose falling actuation SPST-NO switches to power a heater or activate an alarm. Choose falling actuation SPST-NC switches to turn off a cooler or other equipment when the temperature falls to the setpoint.

IP67 Enclosure Rating—IP67 rated switches stand up to temporary submersion.

UL Recognized Component—UL and C-UL listed switches meet U.S. and Canadian safety standards.

Compact Threaded Temperature Switches


NPT Male Threaded	NPT Male × NPT Male Threaded

Since these switches don’t have a housing above the probe, they are often used in tight spaces and low-clearance areas. The threaded probe installs directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature. Use the adjustment screw to set the actuation point. All switches are SPST (single pole, single throw) and control one circuit.

1 Off Switch Starting Position—Switches with 1 Off Switch Starting Position turn the circuit from off to on.

Washdown Autotuning Temperature Controllers

The faceplate on these controllers is sealed to meet NEMA 4X and IP66 for protection in washdown environments with splashing water, corrosive liquid, and dust. The rear case meets IP20, which prevents objects about the size of a finger from coming into contact with a live circuit.

Because they have proportional-integral-derivative (PID) software, these controllers are ideal for turning heating equipment on and off in systems with rapid, unpredictable, and complex temperature changes. They help you achieve precise and stable temperature control with fuzzy logic that learns system behavior and automatically compensates for changes. Use the autotuning function to cycle and identify the ideal PID variables for your system to achieve the most precise control. These controllers read temperature with a highly sensitive thermocouple probe (sold separately) in critical process applications. All fit into instrument panels with DIN cutouts. Use the keypad to adjust the actuation point, reset point, and other settings.

Controllers with Mechanical Relay Heating Output


For 1/32 DIN Panel Cutout Size	For 1/16 DIN Panel Cutout Size

For 1/8 DIN Panel Cutout Size	For 1/4 DIN Panel Cutout Size

Mechanical relay outputs actuate circuits directly.

SPDT—Single pole, double throw (SPDT) relays can be set to turn the circuit from off to on (normally open) or from on to off (normally closed).

SPST-NO—Single pole, single throw (SPST) relays turn one circuit from off to on (normally open).

Automatic Reset—Controllers with automatic reset switch off and on again automatically as the temperature fluctuates.

Manual Reset—Controllers with automatic/manual reset give you the choice to have machines turn back on either automatically when the temperature fluctuates, or you can manually reset their switch. When set to manual they shut down your machine when it gets too hot to protect equipment and personnel. They won’t turn the machine back on until you reset their switch. They have a second output to actuate an alarm or another simple device.

1 Off Switch Starting Position—Switches with 1 Off Switch Starting Position turn the circuit from off to on.

Autotuning Temperature Controllers

Ideal in systems with rapid, unpredictable, or complex temperature changes, these controllers turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control. They work similarly to proportional controllers but gather more variables to calculate the most effective way to return to the target temperature and avoid overshooting. They also have fuzzy logic to learn your system's behavior and compensate as needed. Use the autotuning function to have the controller cycle and identify the ideal PID variables for your system. You can also manually select the PID variables. These controllers read temperature with a highly sensitive thermocouple or RTD probe (both not included) in critical process applications. Since they reset automatically, they switch off and on again as the temperature fluctuates. All fit into instrument panels with DIN cutouts. Use the keypad to adjust the actuation point, reset point, other settings.

All meet American, Canadian, and European safety standards.

Controllers with high-limit control let you attach a second thermocouple probe to take the temperature of your heating equipment. If your equipment reaches the high limit, these controllers shut down your heating equipment and won't let it turn back on until you manually reset it, improving the safety of your system.

High-Limit Temperature Controllers

To protect equipment and personnel, these controllers shut down your machine when it gets too hot. Reset them manually to turn your machine on again. They're often used as a fail-safe system and for triggering alarms.

Set the actuation point and adjust other settings with the keypad. To read the temperature, these controllers use a highly sensitive thermocouple probe (sold separately). They have one or two mechanical relays that actuate circuits directly. Mount them into instrumentation panels with DIN cutouts.

SPST-NO—Controllers that are SPST-NO (single pole, single throw) can turn one circuit from off to on (normally open).
