Adjustable-Reset Electronic Temperature Switches
An adjustable reset lets you control the amount of temperature change, also known as deadband and differential, before these switches reset. Twist the rings to select the setpoint temperature and reset temperature anywhere within the setpoint range. When they reach the set temperature, they send an electronic signal to your programmable logic controller (PLC) to turn equipment on or off. Because they control two circuits, they turn one device from off to on (normally open) and another from on to off (normally closed). An LED illuminates to indicate they’re switching. These switches are often used in control and automation in hydraulics, pneumatics, air-conditioning, and refrigeration applications. Made of stainless steel, they resist corrosion and chemicals.
Install these switches directly into tanks, pipelines, and other process components using their threaded probe. They have a micro M12 plug connection and are compatible with micro M12 sockets, so you can quickly connect and disconnect them. After selecting your setpoint, tighten the locking ring to prevent unintentional changes.
IP rated, these switches seal out dust and water from temporary submersion. They also meet U.S., Canadian, and European safety standards.

Dual-Setpoint Electronic Temperature Switches
Send signals to trigger two different processes, each with their own set temperatures. For example, use one setpoint to turn a heater on and off at one temperature and another to activate an alarm if the temperature rises too far above the cutoff point. Twist the outer ring to adjust your setpoints—no need for tools. After choosing your setpoint, tighten the locking ring to prevent unintentional changes. Once the setpoint is reached, an LED illuminates, indicating the switching status. The threaded probe installs directly into tanks, pipelines, and other process components.
These switches send an electronic PNP signal to your programmable logic controller (PLC), so they’re often used in control and automation applications. They have a micro M12 plug connection and are compatible with micro M12 sockets, allowing you to quickly connect and disconnect the switch.
They are rated IP67 for protection from dust and temporary submersion.

Autotuning Temperature Controllers
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. They work similarly to proportional controllers but gather more variables to calculate the most effective way to return to the target temperature and avoid overshooting. They also have fuzzy logic to learn your system's behavior and compensate as needed. Use the autotuning function to have the controller cycle and identify the ideal PID variables for your system. You can also manually select the PID variables. These controllers read temperature with a highly sensitive thermocouple or RTD probe (both not included) in critical process applications. Since they reset automatically, they switch off and on again as the temperature fluctuates. All fit into instrument panels with DIN cutouts. Use the keypad to adjust the actuation point, reset point, other settings.
All meet American, Canadian, and European safety standards.
Mechanical relay outputs actuate circuits directly. All are single pole, single throw (SPST) relays and turn one circuit from off to on (normally open). Solid state relay drive outputs send a pulse signal to directly control an external solid state relay (not included). They have a longer service life than mechanical and signal relays. Use them for more precise and rapid control switching than mechanical relays. Analog signal outputs are typically used with SRC (silicon controlled rectifier) power controllers (not included) for some of the highest precision control.
Alarm outputs can also be configured to actuate simple devices.
IP20 rated controllers prevent objects about the size of a finger from coming into contact with a live circuit. IP50 rated controllers protect against dust.
DIN-rail/surface-mount adapters (sold separately) mount 1/16 DIN controllers to a DIN rail or surface.
DIN cutout adapters (sold separately) convert larger cutouts to fit 1/16 DIN controllers.

Benchtop Autotuning Temperature Controllers
Built into an enclosure, these temperature controllers are protected when sitting on your workbench. Ideal in 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. All work similarly to proportional controllers but gather more variables to calculate the most effective way to return to the target temperature and avoid overshooting it. They also have fuzzy logic to learn your system's behavior and compensate as needed. Use the autotuning function to have the controller cycle and identify the ideal PID variables for your system. These controllers read temperature with a highly sensitive thermocouple probe in critical process applications. Since they reset automatically, they switch off and on again as the temperature fluctuates. Use the keypad to adjust the actuation point, reset point, and other settings.
The controllers have mechanical relay outputs that actuate circuits directly. All are single pole, single throw (SPST-NO) relays and turn one circuit from off to on (normally open).
Controllers with high-limit control let you attach a second thermocouple probe to take the temperature of your heating equipment. If your equipment reaches the high limit, these controllers shut down your heating equipment and won't let it turn back on until you manually reset it, improving the safety of your system.
Controllers with two control zones let you independently turn heating equipment on and off in two separate areas, each with their own thermocouple input and heating control output.

DIN-Rail-Mount Autotuning Temperature Controllers
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. All work similarly to proportional controllers but gather more variables to calculate the most effective way to return to the target temperature and avoid overshooting. They also have fuzzy logic to learn your system's behavior and compensate as needed. Use the autotuning function to have the controller cycle and identify the ideal PID variables for your system. These controllers read temperature with a highly sensitive thermocouple or RTD probe (both not included) in critical process applications. Since they reset automatically, they switch off and on again as the temperature fluctuates. Use the keypad to adjust the actuation point, reset point, and other settings.
All meet American, Canadian, and European safety standards.
Mechanical relay outputs actuate circuits directly. All are single pole, single throw (SPST) relays and turn one circuit from off to on (normally open). Solid state relay outputs send a pulse signal to directly control an external solid state relay (not included). They last longer than mechanical and analog signal relays. Use them for more precise and rapid control switching than mechanical relays. Analog signal outputs are typically used with SRC (silicon controlled rectifier) power controllers (not included) for some of the highest precision control.
Alarm outputs can be configured to actuate alarms or other simple devices. Those with cooling/alarm outputs can also be used to turn cooling equipment on or off at a specified temperature.

Proportional Temperature Controllers
Cycle heaters on and off intermittently to maintain a set temperature in your system. These proportional controllers keep your heater on when your system is below the set temperature, and they turn it off in short cycles when your system nears the set temperature. The short cycles make them more precise and allow less temperature fluctuation than on/off controllers. Use them on electric heaters only—they don't work with valves or solenoids.
Turn the dial on these controllers to choose your set temperature. They use a highly sensitive thermocouple probe (not included) to read temperature. Their mechanical relay actuates circuits directly. All are SPDT (single pole, double throw) and can turn one circuit from off to on (normally open) or on to off (normally closed). Install these controllers into instrument panels with DIN cutouts.
All controllers meet American, Canadian, and European safety standards.
To mount 1/16 DIN controllers to a surface or DIN rail, add DIN-rail/surface-mount adapters. To convert larger cutouts to fit 1/16 DIN controllers, add DIN cutout adapters.

Electronic Insertion Flow Switches
Instead of disassembling your system for inline installation, thread these flow switches onto a mounting adapter (sold separately) and insert them into a pipe tee or pipe outlet. They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. These switches are accurate in any mounting orientation.
IP65 rated switches protect against dust and washdowns. IP67 rated switches withstand temporary submersion.

Sanitary Electronic Insertion Flow Switches
Easy to clean and install, these flow switches are 3-A certified to meet sanitary design standards and insert into your line with a quick-clamp mounting adapter (sold separately). They have a smooth probe, and unlike flow switches that measure with a paddle or turbine, these don’t have moving parts for contaminants to get stuck in. Rated IP67 and IP69K, they withstand temporary submersion and high-temperature, high-pressure washdowns. The mounting adapter attaches to a quick-clamp tube tee or outlet (often called tri-clamp fittings) in your large-diameter tubing system using a gasket and clamp (not included), so you don't need to disassemble your line for inline installation. This mounting adapter is also easy to remove and clean.
They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures.
