Lämpötilasiruja

Lämpötilasiruja, also known as temperature sensors or thermistors, are electronic components used to measure temperature. They are typically small, semiconductor devices that change their electrical resistance based on temperature variations. This change in resistance can then be converted into a temperature reading.

There are two main types of thermistors: NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient). In NTC thermistors, resistance decreases as temperature increases. Conversely, in PTC thermistors, resistance increases with rising temperature. The specific material composition of the thermistor determines its characteristic temperature-resistance relationship.

Lämpötilasiruja are widely employed in a diverse range of applications due to their accuracy, small size, and cost-effectiveness. They are commonly found in consumer electronics such as smartphones, laptops, and home appliances like refrigerators and ovens. In the automotive industry, they are used to monitor engine temperature, coolant levels, and other critical parameters. Medical devices also utilize lämpötilasiruja for accurate temperature monitoring in patients. Industrial automation, environmental monitoring, and scientific research are further areas where these sensors play a vital role. Their reliability and sensitivity make them a preferred choice for precise temperature measurement in various environments and conditions.
