For high accuracy in applications with fluctuating conditions, these controllers have proportional-integral-derivative (PID) software with fuzzy logic that learns system behavior and automatically compensates for changes.

Install these controllers into instrument panels.

These lightweight controllers have a carrying handle.

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

Housing is UL listed for environments with flammable gases, combustible dust, and ignitable fibers, such as chemical plants, refineries, and grain elevators.

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

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

Install directly into drilled and reamed holes.

Plug in the thermostat, then plug your heater into the socket on the thermostat's plug.

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

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.

Use to regulate line-voltage HVAC systems where flammable gases, vapors, and dust are present. Thermostats are rated Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

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

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

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.
