Industrial heating systems are complex and there is a need for accurate control to deliver the best performance with safety. An important component is the heat control sensor. These sensors are the ‘control centres’ of the heating system because they are primarily responsible for measuring, maintaining, and regulating the temperatures. Knowledge and selection of the heat control sensor can influence the success of heating in industrial heating applications. We are going to discuss the working of heat control sensors, their components, benefits and selection criteria in this guide.

How Heat Control Sensors Work?

Heat control sensors are defined as devices that measure the heat and provide information to the heating regulating system. This turn controls the heat element in the heaters. These sensors can instantly determine the temperature variation so that the heating can be controlled accurately. Some of the widely used heat control sensors are:

Thermocouples: They are widely used because they respond quickly and work well over a wide range of temperatures. They operate by creating voltage that changes with temperature, which the control system determines to regulate heating.

Resistance temperature detectors abbreviated or RTDs: RTDs, on the other hand, are more accurate than thermistors and have very good stability and are ideal for use in temperature control circuits.

Components of a Control Panel

The control panel should easily accommodate heat control sensors as well as facilitate efficient systems control. Key components of a control panel include

Contactors: These switches are operated electrically and used in switching power circuits. These are used in the management of high-power devices.
SCR and SSR: Silicon Controlled Rectifiers (SCR) and Solid State Relays (SSR) are used for switching and regulating heaters with reliability and efficiency.
Relays: These switches open and close circuits either electromechanically or electronically. These are essential for regulating various sections of the heating system.
Temperature Controllers: These devices control the temperature and keep the set temperature for a longer-time. It works with heat control sensors to control heating.
Fusing Devices: These safety devices safeguard the heating system against overcurrent situations.

Terminal Boxes: Based on use, terminal boxes protect from moisture, explosion, water and dust.

Benefits of Heat Control Sensors

The main advantage of heat control sensors in industrial heating systems is that it help to keep the temperature constant in the system. This stability is essential in applications where it is necessary to maintain the heat input at a steady level, for example, chemical industry, food industry, and material production.

Safety: Heat control sensors measure heat and prevent overheating that can harm the equipment or create a dangerous environment. These sensors give feedback on temperature on a real-time basis, ensuring heating elements are safe to operate.
Efficiency: Through accurate maintaining of the temperature, heat control sensors reduce energy use. This efficiency cuts the cost of production and also reduces negative impacts on the environment.
Precision: Heating control sensors make it possible for a system to allow for better control of heat that may be needed to perform specific tasks or meet specific temperatures that are required in production.

Selecting the Right Heat Control Sensor

Selecting the heat control sensor requires several factors to be taken into consideration so that the sensor used is compatible with heating applications, such as:

Temperature Range:

Make sure that the sensor operates within the necessary temperature range needed by the application. Thermocouples are excellent for high-temperature applications, while RTDs work well in applications that require a higher degree of accuracy within a limited temperature range.

Response Time:

Choose the sensor whose response time corresponds to the dynamics of the heating process. Shorter response times are needed for processes that undergo frequent temperature variations.

Accuracy:

Accuracy can be conditional to the application in certain instances. The accuracy of RTDs generally tends to be greater than that of thermocouples.

Environmental Conditions:

Taking into account the operating environment, heat control sensors should have the ability to perform under harsh environmental conditions like moisture, risk of corrosion, and physical wear out.

Integration with Control Panels:

Make sure the sensor can be easily mounted on the existing control panel and other parts of the machinery. Integration with the digital temperature controller and safety system should be necessary.
