Introduction

Temperature sensors are devices that measure the temperature of objects and enable the temperature data to be read, measured and monitored. There are many different types of temperature sensors, such as Analog and Digital Output temperature sensors, which can be used in various applications. In this paper, we will discuss the application field and working principle of the LM135Z temperature sensor. The LM135Z is a non-digital, analog output temperature sensor.

Description of the LM135Z

The LM135Z is a three-terminal analog temperature sensor that is designed for applications where a temperature range of -55°C to +100°C needs to be read. It has great stability and accuracy over this wide temperature range and it is capable of measuring temperatures in this range, even with a some fluctuations. When it is connected to the control circuitry, the LM135Z will output a voltage signal proportional to its temperature in the external environment. The LM135Z is a compact device with a flexible design, which makes it easy to be integrated into existing systems. It includes all of the necessary components needed to accurately measure temperature with minimal interference from external electronic equipment. It is highly sensitive to temperature changes and can detect very slight increments or decrements in temperature.

Application Fields of the LM135Z

The LM135Z is a temperature transducer primarily used in industrial control systems, but it can also be used for home or commercial applications. It is suitable for any environment that needs to accurately monitor temperature and detect small changes in temperature levels. Its excellent stability and accuracy make it a great choice for demanding applications that require accurate temperature readings over a wide temperature range. Some of the most popular application fields of the LM135Z are in process and industrial temperature monitoring, HVAC systems, agricultural and farming applications, instrumentation systems, and energy management systems.

Working Principle of the LM135Z

The LM135Z uses a thermopile principle to measure temperature. It is essentially a voltage-to-temperature converter with a thermopile at the core. It converts a temperature change into a proportional electrical change, which is then converted into an output voltage. The LM135Z has two different measuring temperature ranges, internal and external. The internal temperature range covers temperatures from -55°C to +100°C and the external temperature range covers temperatures from 0°C to +50°C. When the temperature changes in either the internal or the external range, the voltage output of the LM135Z will also change accordingly.

Conclusion

The LM135Z is a three-terminal analog output temperature transducer designed for applications in industrial control systems. It is highly reliable and accurate and it can be used to measure temperatures in the -55°C to +100°C range, even with slight variation. Its highly flexible design makes it an ideal choice for various applications, such as process and industrial temperature monitoring, HVAC systems, agricultural and farming applications, instrumentation systems, and energy management systems. The LM135Z uses a thermopile principle to measure temperature and it can detect small temperature changes in either the internal or the external temperature range.
