What qualities does a temperature switch have?
As already mentioned at the beginning, a temperature switch continuously monitors the temperature of a medium and, as soon as a predefined value (also known as a switching point) is reached, triggers an electrical switching process. Whether this becomes active or not depends on the temperature. Depending on the system, the temperature switch triggered the system when the switching point is exceeded or ventilation sets off. The aim is to always avoid overheating or to comply with specific temperature conditions. A temperature switch can come as an independent control unit or be integrated into a system as part.
How does a temperature switch work?
In principle, the functioning of a temperature switch is as simple as it is ingenious. Using the sensors, mostly bimetal strips or a thermocouple, the device continuously measures the temperature and thus perceives even the smallest temperature changes. If this falls or increases, the physical or electrical properties of the sensor element change.
The switching point, the limit at which the temperature switch is supposed to trigger an action, is defined by the user in advance. A practical setting wheel is usually installed for this. Modern variants often bring digital interfaces.
If the measured temperature now reaches the preset switching point, the temperature switch triggers an action. In the case of a mechanical temperature switch, as with a bimetal strip, the deformation of the metal strip causes due to temperature changes to touch two contact pieces or separate from each other, which closes or opens the circuit.
Closing or opening the circuit through the temperature switch can trigger different actions. These are mostly the switching on ventilation or switching off the system. An alarm can also be triggered, for example, which enables users into a quick, manual intervention. Depending on the type of temperature switch, the regular operation is restored or a manual provision is required.
What are the advantages of a temperature switch?
In many ways, the functionality of temperature switches has a number of significant advantages that primarily affect industrial environments.
This includes:
- Easy integration and operation
- High accuracy in temperature measurement and control
- Inexpensive purchase and maintenance
- Reliability, robustness and durability
- Maximum security before overheating, risk of fire and other safety -relevant incidents by automatic control of systems when critical temperatures are reached
- Different versions, designed for a variety of applications and media such as liquids and gases to solid surfaces
- Reduction of errors, since no human intervention is required
- Independence in the operation of external power supply and control systems
- Adaptation of the individual switching point
Where are the areas of application of a temperature switch?
The outstanding of temperature switches is that they offer themselves for a wide range of areas of application and that across the sector.
Areas of application of temperature switches
- Mechanical engineering and plant operation for monitoring machine temperatures
- Heating, ventilation and air conditioning technology (HLK) to regulate room and water temperatures
- Food processing for compliance with strict temperature conditions
- Plastic industry in extrusion and shape processes
- Chemical and pharmaceutical industry for precise process controls
- Household appliances such as ovens and boilers to avoid overheating
- Electronics for temperature control in sensitive circuits
- Energy generation and distribution for temperature monitoring of transformers and generators
- Medical technology for the exact temperature control in medical devices
Selection criteria for temperature switches
- Temperature range:The temperature range must be suitable for specific application and include both the minimum and maximum operating temperature.
- Switching behavior and accuracy:The sensitivity and accuracy with which the temperature switch addresses is crucial for process control.
- Material tolerance:The materials used must be compatible with the media, the temperature of which is monitored to avoid corrosion or material fatigue.
- Switching performance:The temperature switch must be able to switch the required electrical load safely.
- Reliability:A long service life and low error rate ensure permanent operational safety.
- Environmental conditions:The devices must be designed according to the ambient conditions, such as temperature, moisture and vibration.
Optimal installation conditions
- Assembly location:Installation should take place at one point where the temperature switch has direct contact with the medium to be regulated and enables representative measurements.
- Accessibility:The switch should be easily accessible for maintenance and test.
- Environmental conditions:Avoid installations near heat sources or in areas with extreme environmental conditions, unless the switch is specially designed for such conditions.
- Correct installation:Make sure that the temperature switch is installed correctly in accordance with the manufacturer's requirements in order to avoid malfunctions.
