Oscillators are treated as electrical circuits and play an important role in determining the frequency or the time of specific events or operations. KD3270034 is one of the oscillators and generally used in measuring temperature. Its application field and working principle also deserve attention.

Application Field

KD3270034 is an integrated circuit oscillator. The application of this product includes:

• Measurement of temperature in PC Power supply systems.
• Power Supply with fan control.
• Measurement of engine temperature in vehicles.
• Measurement of motor temperature in electric motorcycles.

These fields prove that the KD3270034 is capable to measure the temperature and prove its application field. It is widely used in measuring temperature. Low power consumption and wide temperature range make it suitable for measurement and can be adjusted according to different demands.

Working Principle

KD3270034 oscillator mainly consists of two parts: the oscillation loop and the frequency stable high precision oscillation chip. The oscillation loop connects with oscillation chip and is responsible for generating a stable frequency. It has a rectangular waveform when plugged in the power supply.

The frequency of the rectangular wave is determined by the resistance (R) and capacity (C). As the frequency changes, the oscillation loop produces different signals, thus the temperature can be measured. There is also a temperature sensor in the circuit,when the temperature changes, the resistance of sensor changes accordingly, and thus affects the frequency of rectangular wave.

KD3270034 is an integrated circuit oscillator, it can detect the changes of temperature in a very narrow range. When using resistance temperature detector to get the temperature, a temperature coefficient will appear, which is relatively high in overheat situations. This oscillator can compensate this coefficient and then achieve exact temperature.

Conclusion

KD3270034 is an advanced integrated circuit oscillator. It is mainly used in measuring temperature in PC power supply systems, vehicles, and electric motorcycles. Its working principle is also simple, using oscillation loop to generate rectangular waveform and then get the frequency according to capacity and resistance. Special temperature sensor is also added in the circuit so that the oscillator can detect the temperature changes in a very narrow range. In conclusion, KD3270034 is indeed reliable for temperature measurement.
