Industrial heating control
An industrial heating control is a device for industrial systems that controls , safeguards and monitors electrical heating elements such as B. takes over infrared heaters.
background
In manufacturing processes in which temperature is a critical parameter, deviations of just a few degrees can cause enormous quality problems. In order to avoid this and to minimize the reject rate, a highly precise, reliable and individual control of the ohmic loads is essential. This is why users around the world in numerous industries - from the automotive industry to the food and beverage industry - use compact industrial heating controls.
Basics
In principle, a suitable switching element and fuse protection are required to control an electrical heating element . In order to be able to operate several electrical heating elements in industrial systems in an automated manner, it is also necessary to connect each individual switching element to an output of a programmable logic controller . If the failure of an individual electrical heating element is to be detected, suitable measuring devices must be integrated into the system's automation concept.
advantages
Compact industrial heating controls have mostly integrated switching elements, fuses and diagnostic devices in one unit and have usually a fieldbus - interface that enables connection to a programmable logic controller.
This offers the following advantages:
- Saving space in the control cabinet
- Reduction of the wiring effort
- short maintenance times through localized error messages
- high level of plant safety through early detection of faults
- convenient operation, control and monitoring of the electrical heating elements in the programmable logic controller
application areas
In fact, there is hardly an industrially manufactured product today that is not thermally treated at least once during its creation. Industrial heating controls therefore control heating processes in many branches and branches of industry.
Food and luxury food industry
In the food and beverage industry, industrial heating controls contribute to the product properties required there, e.g. B. when roasting nuts, when welding food or when prebaking ready-made meals.
Photovoltaic industry
In the photovoltaic industry, compact heating controls ensure an exact temperature profile and thus ensure that the efficiency of the solar cells is maximized, e.g. B. in substrate drying or when preheating diffusion and sputtering processes.
Automotive industry
In the automotive industry , materials go through a variety of thermal processes that require extremely precise control in order to ensure optimal end products, e.g. B. when drying paints / coatings or heating plastic strips.
Plastics industry
The process and product temperature is in the plastics industry, e.g. B. in thermoforming , PET blow molding , blow molding or in extrusion , an important factor for the quality of the end product, if not the most important.
