Instruments for monitoring and automatically revising process parameters such as temperature, pressure, force, humidity, level and flow.
Batch controllers maintain the correct size of a discrete batch of process material, such as the volume of a liquid. They are often interfaced with sensors such as load cells, or with volumetric flow meters.
Boiler controllers monitor and maintain variables such as steam temperature and pressure in order to control a boiler’s burner or air mixture.
Brake controllers are used to control braking systems. They can simply engage and disengage the brake, or control the speed of engagement, breakaway torque, and other variables.
CNC controllers are used to control machines and processes. They provide capabilities ranging from simple point-to-point linear control to highly complex algorithms with multiple axes of control. CNC controllers are used to retrofit many types of machine shop equipment.
Environmental controllers control environmental factors such as temperature, humidity, and air pressure. The environment to control can be an office or workspace, or inside a chamber for testing or process purposes.
Flow controllers monitor and maintain flow-rate variables, typically in process applications.
Furnace controllers are used to control temperature, heat delivery, and other variables in industrial furnaces. They control the burner flame, air mixture and trim to maintain and optimize furnace performance.
Hot runner controllers are specialized temperature controllers that keep specialized injection-mold components at the design temperature in order to keep the mold material flowing.
Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms.
HVAC controllers are used to monitor and control heating, ventilation and air conditioning (HVAC) systems in buildings. They monitor indoor environmental factors such as temperature and humidity, and control heating and cooling to maintain desired levels.
Laboratory controllers are designed specifically to monitor and/or control variables involved in laboratory or scientific experimentation, testing, or sample preparation. They are often used to control temperature, but may also control other variables.
Level controllers monitor, regulate, and control liquid or solid levels in a process.
Lighting controls include monitors, communication systems, and other devices for controlling facility lighting systems.
Machine controllers and monitors use electronic numeric control and monitoring interfaces for programming and calibrating computerized machinery.
Mixing controllers and blending controllers govern the ratio, mixing or blending parameters of two or more ingredients in a process. They are used to control the addition of gas or air, liquids, and/or solids.
Motion controllers range from simple linear controllers to complex, user-programmable modules that act as controllers within complex integrated multi-axis motion systems.
pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application.
Predictive maintenance (PdM) systems and condition monitoring systems are used to predict equipment maintenance, and to monitor corrosion, oil condition, bearing wear, overheating and other parameters than can lead to the breakdown of capital equipment.
Pressure controllers accept input from pressure sensors, transmitters, gauges, and other devices and subsequently control adjustment to the pressure to maintain or achieve the desired pressure level.
Process monitors measure and analyze temperature, pressure, flow and other processing parameters to maintain product quality and safe production operating conditions.
Programmable automation controller (PAC) modules are add-on devices that perform a specific control function in PAC systems.
Programmable automation controller (PAC) systems consist of PAC modules, each of which performs a specific function. PAC systems are used in motion control, machine control, machine vision, and other industrial control applications.
Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control. PACs are functionally similar to programmable logic controllers (PLC), but provide the advanced software features of personal computers (PC).
Programmable logic controllers (PLC) are the control hubs for a wide variety of automated systems and processes. They use a wide variety of inputs and outputs and provide network capability.
Pump controllers monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed, output pressure, etc.
Purge controllers and purge indicators are used to regulate and monitor hazardous environments within enclosures.
Specialty industrial process controllers are used in unlisted, specialized or proprietary applications.
Speed controls, including speed regulators and rate controllers, are used to decelerate and regulate the speed of loads such as moving carriages and machining feeds near the end of their travel.
Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level.
Tool monitors optimize machine tool operating conditions based on feedback from a sensor or probe.
Universal process controllers constitute a broad area of control devices that may be employed in the monitoring and control of many different process variables, including temperature, pressure, flow and other values.
Vacuum controllers monitor and control vacuum levels for process equipment such as vacuum furnaces, autoclaves, and coating machines.
Web controllers maintain control functionality over processes with web or sheet rollers. Control functionality includes maintaining tension of the web, centering on the track, and material feed rates.
Web tension indicators measure and report tension parameters in web or other flat-sheet production processes. Some types of web tension indicators have control functionality as well.
