Temperature Sensors - Analog and Digital Output

Temperature sensors are devices used to measure temperature. Generally, they are categorized into two types - Analog and Digital Output. Temperature sensors that provide a digital output such as LMT84DCKT are becoming increasingly popular due to their ease-of-use and accuracy. In this article, we will discuss the general application fields and working principles of LMT84DCKT temperature sensors.

Applications of LMT84DCKT Temperature Sensors

LMT84DCKT temperature sensors are widely used in industrial and commercial applications. They are particularly suitable for controlling ventilation, air conditioning, and heating systems. Additionally, they are commonly used in automotive electronics, air compressor control systems, and space flight systems.

Furthermore, the LMT84DCKT is particularly useful in safety-critical applications because of its high reliability and accuracy. They are commonly found in safety monitoring and control systems such as temperature control systems in power plants, fire protection, and industrial refrigerators.

Working Principle of LMT84DCKT Temperature Sensors

The LMT84DCKT temperature sensors use a thermistor to measure temperature. A thermistor is a resistor that changes its resistance with temperature. The LMT84DCKT has a small nickle-based thermistor that can measure temperatures ranging from 0 to 150°C.

The sensor measures the temperature using a four-wire method. In this method, two wires are used to measure the temperature while two other wires are used to measure the reference temperature. This method eliminates the need for a separate ground connection and allows for accurate temperature measurement.

The thermistor in the LMT84DCKT is connected to a precision analog-to-digital converter. This converter converts the analog signals from the thermistor to digital form, which can then be read by the microcontroller.

Conclusion

The LMT84DCKT temperature sensors can be used in many different applications due to their accuracy and reliability. They are commonly used in industrial and commercial applications, as well as safety-critical applications. The sensor measures temperature using a four-wire method, which eliminates the need for an additional ground connection and ensures accurate temperature measurements.
