Industrial Temperature Controls: Improving Process Accuracy and Reliability
Temperature control is an important part of many industrial processes. Whether a manufacturing operation is heating air, liquids, equipment, or another material, maintaining the correct temperature can directly affect product quality, equipment performance, and process consistency.
Industrial temperature controls provide manufacturers with a way to monitor process conditions and adjust heating equipment as needed. The right control system can help maintain a stable operating temperature while giving operators greater visibility into what is happening within the process.
What Are Industrial Temperature Controls?
Industrial temperature controls are devices and systems used to monitor and regulate temperature within a manufacturing or processing application. A typical system may include a temperature sensor, controller, power control device, and heating element.
The temperature sensor measures the process temperature and sends that information to the controller. The controller compares the measured temperature with the desired setpoint and determines whether the heating equipment needs to increase, decrease, or maintain its output.
Different applications require different types of temperature control. A simple application may only require a basic temperature controller, while a more complex process may benefit from multiple control loops, data recording, programmable functions, alarms, and communication capabilities.
Seagate Control Systems provides a broad selection of temperature controls along with the sensors, power controls, and other components needed to build complete systems. The company also has experienced control engineers available to help with application requirements.
Why Accurate Temperature Control Matters
Temperature variations can create problems throughout a manufacturing process. A process that becomes too hot may damage materials or equipment, while insufficient heating can prevent a process from reaching its required conditions.
Consistent temperature control can help manufacturers maintain repeatable operating conditions. This can be particularly important when a process has a narrow acceptable temperature range.
Modern temperature controllers can also provide additional functionality beyond basic temperature regulation. Depending on the equipment selected, features may include alarms, timers, data logging, communication capabilities, multiple control loops, and programmable profiles.
For example, some advanced controllers are designed to combine temperature PID control, data logging, over and under temperature limits, power switching, timers, counters, math functions, and logic within one system.
Components of a Temperature Control System
A complete temperature control system usually consists of several components working together.
Temperature Sensors
Temperature sensors measure the actual temperature of the process. Thermocouples and RTDs are commonly used in industrial applications, with the appropriate sensor depending on temperature range, accuracy requirements, installation conditions, and the process itself.
Temperature Controllers
The controller receives information from the temperature sensor and uses that information to determine how the heating system should operate. Controllers range from simple single loop devices to advanced systems capable of managing multiple loops and programmed temperature profiles.
Power Controls
Power controls regulate the electrical power delivered to a heating element. Solid state relays and SCR power controllers are examples of components used to control electric heat.
Seagate offers power controls and solid state relay products designed for industrial heating applications.
Heating Equipment
The heating element or heater performs the actual heating required by the application. Depending on the process, this may include air heaters, band heaters, cartridge heaters, circulation heaters, immersion heaters, infrared heaters, or other specialized heating equipment.
Choosing the Right Temperature Controller
There is no single temperature controller that is appropriate for every application. The process requirements should determine the equipment selected.
Important considerations can include the required temperature range, number of control loops, sensor type, power requirements, response time, environmental conditions, communication requirements, and whether data recording or programmable profiles are necessary.
The type of heater being controlled is also important. A temperature controller must work with the rest of the heating system to provide the desired level of control.
Working with an experienced application engineer can make it easier to identify the appropriate combination of components. Seagate Control Systems works with industrial customers to help address heating requirements and can assist with control system design and component selection.
Temperature Control for Industrial Applications
Temperature control is used throughout manufacturing and industrial processing. Applications may involve ovens, dryers, process equipment, tanks, air handling systems, production machinery, and other equipment where controlled heating is required.
Some processes require basic temperature regulation, while others require precise control over multiple zones or a programmed heating cycle. The control system should be designed around the requirements of the specific process rather than simply selecting a controller based on temperature range alone.
Seagate offers temperature controls, sensors, process heaters, power controls, programmable controls, and related components that can be combined to meet different industrial requirements.
Get Help Selecting Industrial Temperature Controls
Selecting the right temperature control equipment involves more than choosing a controller from a catalog. The sensor, controller, power control, and heater all need to work together within the requirements of the application.
Seagate Control Systems has been serving industrial customers since 1970 and maintains sales offices throughout Ohio. Its engineering staff can help customers evaluate their application and develop an appropriate control or heating solution.
