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.

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.

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

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.

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

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

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.

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.

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.

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.

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

Control one- and two-speed heaters and air conditioners.

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.

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.

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.

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

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