Temperature Sensors – NTC Thermistors are devices used in a variety of applications to measure temperatures between two points. The most commonly used thermistor is the NHQ473B400T10, which is a negative temperature coefficient (NTC) thermistor. The NHQ473B400T10 thermistor can measure temperature for a wide range of applications and works by using an electrical resistance which changes in proportion to temperature.

Applications

The NHQ473B400T10 thermistor is used in several industrial and commercial applications. It is ideal for air conditioning and refrigeration systems as it can accurately measure the temperatures in the systems. The NHQ473B400T10 can also be used in applications such as thermocouples and household electronics. Due to its high temperature range, it is also perfect for automotive and aircraft applications, such as temperature sensors and oil pressure & fuel level gauges. In addition, the NHQ473B400T10 can be used in medical devices for measuring temperatures in the body and in medical diagnostic and research applications.

Working Principle

The NHQ473B400T10 thermistor is a semiconductor device that consists of a bead of a metal oxide ceramic material and has two electrical leads. The thermistor is extremely sensitive to the temperature changes and its sensing range is large compared to other temperature sensing devices. When the temperature rises, the resistance of the thermistor decreases and the same phenomenon occurs when the temperature falls. The NHQ473B400T10 thermistor works by measuring the resistance between the two leads. When the temperature changes, it causes the resistance between the two leads to change. This change is then measured by the electronics in the device and then converted to a temperature reading.

Advantages

The NHQ473B400T10 thermistor has numerous advantages over other temperature sensing devices. One of the main advantages is the high accuracy and sensitivity achieved by the thermistor. As the resistance of the thermistor changes quickly with temperature, the thermistor can measure small variations in temperature which other devices may not be able to detect. In addition, this thermistor is highly reliable, operates within a wide temperature range, and has an extremely long life span. It is also very cost-effective and easy to install.

Disadvantages

While the NHQ473B400T10 thermistor has several advantages, it also has some disadvantages. One disadvantage is that the thermistor is sensitive to shock and vibration, so it should not be used in environments with high levels of vibration or shock. Additionally, the thermistor is not compatible with low-level signals, so it may require additional signal conditioning circuitry if used with low-level signals.

Conclusion

The NHQ473B400T10 thermistor is a versatile device which can be used in a wide variety of applications. It is highly accurate, reliable and cost-effective. However, it is important to ensure that the device is not exposed to high levels of shock or vibration and that it is not used with low-level signals, as this could reduce its effectiveness. Despite its disadvantages, the NHQ473B400T10 is still an excellent choice for temperature sensing applications.
