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.

Built into an enclosure, these temperature controllers are protected when sitting on your workbench. 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.

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.

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.

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.

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

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

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.

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

Safe for use in chemical plants, refineries, and other hazardous locations, these switches maintain your surface’s temperature by turning equipment on or off when they reach a set temperature. They’re FM approved for use where flammable gases may be present.

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.

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.

Regulate line-voltage HVAC systems.

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.

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.

These thermostats work with low-voltage HVAC systems that have only one speed.

Keep electronics in your enclosure from getting too hot or cold with these thermostats that control two devices at once.

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