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 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.

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

Often used to control heat cable output, these switches have mounting holes for surface installation.

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

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.

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.

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

Connect to a Wi-Fi network so you can remotely program, monitor, and control the temperature from a computer, tablet, or smart phone.

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

As the temperature goes up, the pressure in the system goes down.
