Introduction

DG103350 is a type of temperature sensors or NTC thermistors. It belongs to a family of high-precision temperature measurement devices, which measure temperature by utilizing the temperature-dependent electrical characteristics of semiconductor materials such as resistance, capacitance, inductance, Hall effect, thermocouples and thermistors. The core element of the DG103350 is an NTC (Negative Temperature Coefficient) thermistor. It is a temperature-dependent resistor in which the resistance decreases with increasing temperature. The electrical behavior of NTC thermistors offers several advantages such as fast response, good accuracy, repeatability and only requires a small package.

DG103350 Application Field

DG103350 is suitable for applications such as temperature measurement, controller, ovens, freezers, heaters and air conditioners. It is especially suitable for controlling ambient temperature inside a closed environment such as a refrigerator or an incubator. The DG103350 has very low thermal mass and a durable construction, making it ideal for applications where the temperature needs to be stabilized. Additionally, it can measure temperatures ranging from -40℃ to +415℃ and deliver readings with an accuracy within ±0.5℃. It also comes with an integrated temperature-to-voltage converter for providing readings in the analog domain and also contains a communication interface for integrating digital networks.

DG103350 Working Principle

The DG103350 uses the working principle of NTC thermistors. Any NTC thermistor consists of a ceramic material that has been mixed with a metal oxide. It is designed such that the temperature-dependent properties of the material and the metal oxide combines together to change the resistance of the thermistor with temperature variation. When the temperature of the thermistor increases, the resistance of the thermistor decreases according to the NTC principle. The resistance of the thermistor can be measured by using a fixed voltage source. The output voltage is directly proportional to the temperature of the thermistor.

Conclusion

Overall, the DG103350 temperature sensor is an excellent choice for temperature-based control and monitoring applications because of its fast response time, excellent accuracy and repeatability, small package size and communication capabilities. Its NTC thermistor based design ensures cost-effectiveness and long term reliability. This temperature sensor is also suitable for applications such as ovens, freezers, heaters, air conditioners and incubators.
