We are fully familiar with the critical role of temperature measurements in everyday life and across many industries. Temperature measurement supports various aspects of our modern environment, from manufacturing operations to climate management. 

As a result, selecting the appropriate temperature sensor becomes an important aspect of temperature measurement. Throughout this post, we will discuss the most effective approach to selecting and using a suitable temperature sensor for your specific application. 

This post will cover all of the types of temperature sensors, their operating principles, benefits, limitations, temperature range, tolerance, accuracy, and interchangeability.

What is a temperature sensor?

A temperature sensor is just a thermometer that detects temperature and communicates the signal to computers or other temperature monitoring devices. It enables us to determine the temperature of our surroundings, as well as the temperature of machinery and equipment.

Different types of temperature sensors based on the working principle?

Let’s consider the working principle of the temperature sensing instruments. Temperature sensors of several types are commonly used, including:


Working principle of Thermocouples

Thermocouples are another popular choice for temperature sensors. These sensors work on the Seebeck effect, where two different metals joined at one end produce a voltage proportional to the temperature difference between the joined end and the open end. This voltage, known as thermoelectric voltage, is then used to determine temperature precisely.

Resistance Temperature Detectors (RTDs):

Working principle of RTD (Resistance Temperature Detector)

The RTD (Resistance Temperature Detector) is a popular choice for various industries for temperature measurement. It works on an easy principle: when the temperature rises, the resistance of a pure metal wire within it rises accordingly (this wire is typically made up of copper, nickel, or platinum, wrapped around a ceramic or glass core). Because of the linear relationship between resistance and temperature, RTDs are a popular choice for many industrial applications.


Working principle of Thermistor  

Thermistors are temperature-sensitive resistors that change their electrical resistance in response to temperature variations. NTC (Negative Temperature Coefficient) thermistors lose resistance as temperature rises, whereas PTC (Positive Temperature Coefficient) thermistors gain resistance. 

Because of its sensitivity and reliability, thermistors are invaluable for applications such as temperature monitoring and control due to this predictable and precise change in resistance. Thermistors are composed of ceramic materials. They exhibit a large difference in resistance to temperature.

Infrared Temperature Sensors:

(Working principle of Infrared Temperature Sensors)

Infrared temperature sensors work on the principle that all objects emit infrared radiation, and the amount of radiation emitted is proportional to their temperature. These sensors are made up of a lens and a detector that detects the infrared radiation emitted by the object being measured. This radiation then gets converted into an electrical signal by the detector. 

The sensor estimates the temperature of the object by examining the strength of this signal without the requirement for direct touch, giving a non-contact and highly accurate temperature measuring system that is suitable for a wide range of applications.

Each type of sensor has its own advantages and is suitable for specific applications based on factors like temperature range, accuracy, and cost.
