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

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

Regulate line-voltage HVAC systems.

Set these thermostats to adjust the temperature at certain times each day. They regulate heaters that use direct electrical power, such as baseboard and wall heaters.

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

Regulate temperatures in wet locations 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.

Control, monitor, and program your HVAC system from anywhere. These thermostats connect to a Wi-Fi network, so you can use a computer, tablet, or smartphone to view and adjust settings.

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.

Since these switches don’t have a housing above the probe, they are often used in tight spaces and low-clearance areas.

To control heating equipment in washdown environments with splashing water, corrosive liquid, and dust, these switches have a housing that meets NEMA 4X.

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.

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

Install directly into drilled and reamed holes.

An adjustable reset lets you control the amount of temperature change, also known as deadband and differential, before these switches reset. When they reach the set temperature, they send an electronic signal to your programmable logic controller (PLC) to turn equipment on or off.

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

Switch heaters on or off when your process reaches a certain temperature. Both these controllers and your heater will be powered by the same wall outlet.

For protection in washdown conditions with splashing water, corrosive liquid, and dust, these controllers have a wall-mount housing that meets NEMA 4X. They’re ideal for systems with rapid, unpredictable, or complex temperature changes.

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.

Mount these temperature controllers directly onto DIN rail for controlling systems with rapid, unpredictable, or complex temperature changes. They 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.
