Introduction

A NTC (negative temperature coefficient) thermistor is a type of temperature sensor that produces an output voltage that changes in direct proportion to the change in temperature. The NTC thermistor, often referred to as a PW103J2, is a commonly used temperature sensing device. The PW103J2 is frequently used in temperature measurement, control, and house automation due to its low cost, durable construction, and wide operational temperature range.

PW103J2 Features

The PW103J2 NTC thermistor consists of a ceramic or metal element with a layer of a conductive polymer coating. Since there is no contact between the sensing element and any metal element, the PW103J2 is immune to corrosion and dust which makes it a reliable choice for long-term measurements in harsh environments. It has a wide temperature range as it can accurately measure temperatures between -200°C and +300°C. The resistance of the element is also lower than that of competing thermistors, allowing the device to be used in low-voltage applications.

The resistance of the device can also be adjusted by adjusting its operating range. This allows the device to accurately measure temperatures in a wide range of temperatures. Lastly, it is small in size, making it easy to integrate into existing systems.

PW103J2 application field and working principle

The PW103J2 can be used in many applications for accurate temperature measurement. It is commonly used for industrial, medical, marine, and automotive applications. It can be used for measuring surface temperature, in process control, and for environmental temperature monitoring. It can also be used in medical applications such as temperature monitoring during medical procedures and in the monitoring of patient body temperature.

The PW103J2 works on the principle of a voltage divider. When the temperature changes, the resistance of the thermistor changes as well, causing the voltage drop across the divider to change, which results in a corresponding change in the output voltage. This output voltage is then used to determine the temperature. The PW103J2 uses a millivolt or microvolts output voltage, making it suitable for lower-voltage applications.

Conclusion

The PW103J2 is a popular and widely used NTC thermistor that is commonly used in temperature measurement, control, and house automation applications due to its low cost, durable construction, and wide operating temperature range. The device is also adjustable, allowing it to accurately measure temperatures in a wide range of temperatures. Lastly, its small size makes it easy to integrate into existing systems.

The PW103J2 is an effective and reliable tool for temperature measurement and control in industrial, medical, marine, and automotive applications. The device works on the principle of a voltage divider, which results in an output voltage corresponding to the temperature change. This output voltage is then used to determine the temperature.
