Temperature Sensors - NTC Thermistor

B57885S0303F000, is one of the most widely used temperature sensors in the industry. This thermistor is a negative temperature coefficient (NTC) thermistor, meaning that its resistance decreases as the temperature increases. It is primarily used for temperature measurement and control in motor protection, climate-control and other industrial applications. It is made of a sintered bead of metal oxide, providing rugged durability and reliable performance even in extreme environments. In addition, its metal oxide composition makes it less sensitive to temperature delays and therefore more reliable than its PTC thermistor counterparts.

Application Field

As previously mentioned, B57885S0303F000 thermistor is predominantly used in industrial applications such as motor protection, climate-control and others. Its resistance decreases with increasing temperatures that make the thermistor ideal for motor protection as it can detect temperature changes quickly and accurately. Additionally, it can be used in climate-control systems as it can be used to accurately control the temperature level. Furthermore, it can also be used in air conditioners as it can detect changes in air humidity and respond accordingly.

Working Principle

B57885S0303F000 thermistor has a negative temperature coefficient, meaning that its resistance decreases as the temperature increases. This is the central principle of how thermistors work. The NTC thermistor contains a special sintered bead of around 5% metal oxide. This bead is then dipped into an epoxy mixture and heated. The heating process opens up the epoxy and causes the thermistor to become more sensitive to temperature changes. The beads then release extra energy, making it easier to detect even the slightest variations in temperature.

The thermistor is then connected to a power source, so when the temperature changes, the thermistor’s electrical resistance changes as well. This resistance change causes an electrical signal to be sent to the power source. The power source then turns on or off accordingly according to the signal it receives. By this process, the NTC thermistor can measure and monitor temperatures quickly and accurately.

Conclusion

B57885S0303F000 thermistor is a widely used NTC thermistor that is primarily used in motor protection and climate-control applications. Its sintered bead of metal oxide and epoxy mixture makes it very durable and reliable even in extreme environments. Its resistive characteristic is also key in its successful usage in temperature measurement and monitoring. This article has highlighted the application fields and working principles of B57885S0303F000 thermistor to get a better understanding of this thermistor and how it fits into its various uses.
