Temperature Sensors - NTC Thermistors

NTC thermistors are temperature sensors used to measure temperatures in a wide range of applications, from consumer electronics to medical devices. The specific thermistor model under consideration here is the NXRT15XH103FA5B025. This thermistor is a standard 10K ohm NTC (Negative Temperature Coefficient) thermistor manufactured by Omron. It is a small, lead-free, sealed device measuring 0.3inches (7.8mm) square with a 0.4inches (10.2mm) lead length.

NXRT15XH103FA5B025 Application Field and Working Principle

The NXRT15XH103FA5B025 is designed for use in a wide range of temperature sensing applications, including medical, automotive, industrial and consumer electronics. It is suitable for use over a wide temperature range (-40°C to +150°C).The working principle of the NXRT15XH103FA5B025 is based on the property of a NTC thermistor which is its resistance decreases with increasing temperature. The thermistor is a component composed of a ceramic material and metal oxides. This ceramic material is sintered at high temperatures. This sintered material has a negative temperature coefficient which means that its resistance decreases when the temperature increases. When this thermistor is connected to a current, thermal energy generated in the thermistor’s element causes the resistance to vary with temperature, which is measured as a voltage changes. This process is called Seebeck effect.

Advantages of NTC Thermistors over Other Temperature Sensors

NTC thermistors have many advantages over other temperature sensors. They are very fast and accurate sensors which respond quickly to temperature changes. The thermistor is also very small and lightweight which makes it ideal for use in applications where space is at a premium. They are also very robust and durable and capable of withstanding harsh environments and vibration.NTC thermistors also have excellent linearity which makes them ideal when precise temperature monitoring is required. They also feature a wide temperature range and good long-term stability, making them suitable for even the most demanding temperature sensing applications.

Types of NTC Thermistors

NTC thermistors come in a variety of shapes and sizes and are designed for use in a wide range of applications. The most common types of NTC thermistors are the sealed bead type thermistors, which are well suited for general purpose temperature sensing applications, and the surface mount type thermistors, which are designed for use in surface mount applications. The bead type styles offer superior thermal time constants, while the smaller surface mount styles offer a more compact solution. It is important to select the appropriate thermistor for the application based on the size, range, accuracy, and stability requirements.

Conclusion

NTC thermistors are an ideal solution for temperature sensing applications due to their small size, accuracy, speed, and robustness. The NXRT15XH103FA5B025 is a general-purpose temperature sensor that offers reliable and accurate measurement over a wide temperature range. It is suitable for a variety of applications, from medical, automotive, industrial and consumer electronics. Its small size and easy installation make it ideal for use in locations where space is at a premium.
