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.

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.

Regulate the amount of power flowing to your heater with the turn of a dial. Instead of a temperature sensor or input, these controllers work like a dimmer on a light switch.

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.

Cycle heaters on and off intermittently to maintain a set temperature in your system.

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

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

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.

Often used to control heat cable output, these switches maintain your surface’s temperature by turning equipment on or off when they reach a set temperature.

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

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.

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.

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.

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

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

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

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.

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

When duct airflow varies from the setpoint, these actuators open and close until the system requirement is restored.
