Also known as snap discs, these thermostats switch on cooling systems or switch off heating systems when equipment gets too hot.

Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space. Thermostats work with line-voltage HVAC systems.

Commonly used with hydronic heaters, this thermostat senses the temperature of liquids. The thermowell protects the sensor.

Regulate line-voltage HVAC systems.

A built-in guard prevents accidental changes and other tampering and protects these thermostats from damage. These thermostats regulate the temperature in HVAC systems that use direct electrical power.

Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space.

Regulate temperatures in washdown areas for HVAC systems that use direct electrical power, such as air conditioners and heaters.

Control a single heating or cooling device in your enclosure to keep electronics at a safe operating temperature.

Set these thermostats to adjust the temperature at certain times each day.

If ambient air temperature rises above or falls below an actuation point, this thermostat flashes the current temperature reading on the display and shows a “high” or “low” message.

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.

Install the threaded probe directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature.

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.

An airtight seal on these switches blocks out dust, dirt and moisture. They maintain your surface’s temperature by turning equipment on or off when they reach a set temperature.

These temperature switches mount on walls and take remote temperature readings with a probe on a cable.

To protect these switches from splashing water, corrosive liquid, and dust, the housing meets NEMA 4X for washdown conditions.

A digital display makes it easy to monitor the temperature and control when these switches turn heating equipment on and off.

The simplest temperature controllers—they turn devices fully on or off, with no middle state, at a given temperature.

Rated IP65 and NEMA 4X to seal out water and dust, these temperature controllers turn your equipment on and off in areas with frequent washdowns.

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.

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.

To protect equipment and personnel, these controllers shut down your machine when it gets too hot.
