Temperature sensors are devices that provide readable temperature measurements via an electrical signal. The most basic way to measure temperature is using a thermometer; this measures how hot or cold something is. With advances in technology, we now have access to a variety of temperature sensors that are much more accurate.
There are two main categories when it comes to temperature sensors, depending on the type of application being used or the industry you are working in:
- Contact Temperature Sensors
- Non-contact Temperature Sensors
Contact Temperature Sensors measure the degree of hotness or coldness of an object or substance via direct contact. They are generally used to detect a wide range of temperatures in different solids, liquids, or gases.
Non-contact Temperature Sensors are never in direct contact with an object or substance therefore, they are widely used in hazardous environments such as power plant industries. They measure how hot or cold something is via radiation emitted by a heat source.
Different types of temperature Sensors:
- Thermocouple
- Thermistor
- RTD (Resistance Temperature Detector)
- IC Temperature Sensor
- Infra-red Temperature Sensor
Thermocouple
A thermocouple has two wires that contain two dissimilar metals (e.g. copper and constantan) that connect at two different points to form a junction. One point is known as the “cold junction”, kept at a specific temperature, and the other is known as the “hot junction”. When the junction of the two wires experience temperature changes, it generates an electromotive force (EMF). It is this EMF differential between the two wires that records the temperature change. Thermocouples are cost-effective and have an extensive temperature range (-200 °C – 1750 °C).
Key Properties
- Temperature Range: -200°C to +2500°C depending on the type of thermocouple (e.g., Type K, J, T, E, N, R, S, B)
- Accuracy: within ±1°C to ±3°C.
- Working Principle: The Seebeck Effect, which is a phenomenon in which a temperature difference of two dissimilar conductors produces a voltage difference between the two substances.
- Sensitivity: relatively low sensitivity, typically in the range of 10 to 50 µV/°C.
- Fast Response: Thermocouples can respond quickly to changes in temperature, making them suitable for dynamic measurements.
- Cost: Thermocouples are generally inexpensive compared to other types of temperature sensors.
When and where to use Thermocouples:
They are particularly useful in situations where durability, wide temperature range, and fast response time are important. For example:
- Furnaces and Kilns: Monitoring high temperatures in metal production, glass manufacturing, and ceramics.
- Engines and Aircrafts: Measuring exhaust gas temperatures (EGT) to monitor and optimize engine performance. Monitoring turbine and exhaust temperatures in aircrafts.
- Laboratory Experiments: Measuring precise temperatures in chemical reactions and material testing.
- Cooking and Baking: Monitoring temperatures in ovens, fryers, and other cooking equipment.
- Soldering: Monitoring the temperature during soldering processes.
- Semiconductor Fabrication: Controlling temperatures in clean rooms and during chip manufacturing.

Thermocouples, Temperature Probes
Thermistor
A thermistor is a type of temperature sensor whose resistance changes with temperature. One can measure the resistance of a thermistor using an ohmmeter. Thermistors are highly sensitive to temperature changes, making them particularly useful in applications requiring high sensitivity.
NTC (Negative Temperature Coefficient) Thermistor: When the resistance of the thermistor decreases as the temperature increases, the device is called an NTC thermistor. NTC thermistors are more commonly used in temperature measurement and control.
PTC (Positive Temperature Coefficient) Thermistor: When the resistance of the thermistor increases as the temperature increases, the device is called a PTC thermistor. PTC thermistors are often used as resettable fuses or for overcurrent protection.
Key Properties
- Limited Temperature Range: Thermistors typically operate over a narrower temperature range compared to thermocouples, usually from about -100°C to +300°C.
- High Accuracy: Thermistors are highly accurate, with tolerances as tight as ±0.1°C, and may require calibration frequently.
- High Sensitivity: Thermistors have a high sensitivity to temperature changes, with large changes in resistance for small changes in temperature.
- Moderate to Fast Response: Thermistors can have a moderate to fast response time, depending on their size and the medium in which they are used.
- Nonlinear Behavior: Thermistors have a nonlinear resistance-temperature curve, especially NTC types. This nonlinearity can be corrected using calibration tables or equations.
- Inexpensive: Thermistors are generally cost-effective, especially for consumer electronics and household appliances.
When and where to use Thermistors
Thermistors are best used in applications requiring high sensitivity and accuracy over a moderate temperature range. Their small size, fast response time, and cost-effectiveness make them ideal for consumer electronics, medical devices, automotive systems, and many other areas where precise temperature monitoring and control are necessary.
- Consumer Electronics: Thermistors are commonly used to monitor and control the temperature in devices like smartphones, computers, and televisions. They ensure the device operates within safe temperature limits.
- Medical: In medical applications, thermistors provide highly accurate temperature readings in devices such as digital thermometers, incubators, and patient monitoring systems.
- Automotive Applications: Thermistors are used in vehicles to monitor engine temperature, cabin temperature, and battery temperature. They help ensure optimal performance and safety.
- Battery Management Systems (BMS): In rechargeable battery packs, thermistors monitor the temperature to prevent overheating during charging and discharging, thus extending battery life and safety.
- HVAC Systems: In heating, ventilation, and air conditioning (HVAC) systems, thermistors help regulate and maintain the desired temperature by providing feedback to the control system.

RTD (Resistance Temperature Detector)
An RTD (Resistance Temperature Detector) is a type of temperature sensor that measures temperature by correlating the resistance of the RTD element with temperature. They use similar principles to thermistors, but differ in their construction methods and materials. RTDs are known for their accuracy, stability, and wide temperature range. Unlike the thermistor, the change in resistance of RTDs is linearly proportional to temperature. Common materials used for RTDs include platinum, nickel, and copper, with platinum RTDs being the most widely used.
Key Properties
- Wide Temperature Range: RTDs typically operate over a wide temperature range, usually from -200°C to +850°C, depending on the type of RTD.
- High Accuracy: RTDs are highly accurate, with typical accuracy ranging from ±0.1°C to ±0.5°C.
- Moderate Sensitivity: RTDs have a moderate sensitivity to temperature changes, with a relatively linear response. The resistance typically changes by about 0.385 ohms/°C for platinum RTDs (Pt100).
- Slower Response: RTDs generally have a slower response time compared to thermocouples and thermistors, particularly in larger probes.
- Linear Output: RTDs have a nearly linear resistance-temperature relationship, especially in the commonly used temperature ranges. This simplifies the conversion of resistance to temperature.
- Higher Cost: RTDs are generally more expensive than thermocouples and thermistors, especially platinum RTDs, due to the cost of materials and manufacturing.
When and Where to Use RTDs:
- Accuracy Over a Wide Temperature Range: RTDs are ideal for applications that require accurate measurement over a wide temperature range. Example: Aerospace, automotive, and cryogenic applications.
- Stable Long-Term Performance: RTDs are preferred in applications where long-term stability and minimal drift are critical. Example: Climate control systems, environmental monitoring.
- Industrial and Harsh Environments: RTDs are durable and can be used in harsh environments, including high pressure, high temperature, and corrosive conditions. Example: Power plants, oil and gas exploration, and manufacturing plants.

Infrared Temperature Sensors
An infrared (IR) temperature sensor, also known as a non-contact temperature sensor or pyrometer, measures temperature by detecting the infrared radiation emitted by an object. Unlike contact sensors like thermocouples, thermistors, or RTDs, IR temperature sensors can measure temperature from a distance without physically touching the object. Infrared temperature sensors exhibit adaptability to the radiation characteristics of different object surfaces and are unaffected by the material of the object surface.
Key Properties:
-
Distance (Non Contact) Measurement: IR sensors can measure temperature from a distance, allowing for non-invasive temperature monitoring.
-
Wide Temperature Range: IR sensors can measure a broad temperature range, from very low temperatures (e.g., -50°C) to extremely high temperatures (e.g., 3000°C), depending on the sensor.
-
Variable Accuracy: Accuracy can vary based on factors like distance from the object, emissivity of the target surface, and environmental conditions. Typically, accuracy ranges from ±1°C to ±3°C.
-
Fast Response: IR temperature sensors have a very fast response time, often in milliseconds, making them suitable for dynamic processes or moving objects.
-
Real-Time Monitoring: They can provide real-time temperature data for rapid changes in temperature.
-
Output Types
- Analog Output: Some IR sensors provide an analog voltage or current output proportional to the measured temperature.
- Digital Output: Others offer digital outputs via protocols like I2C, SPI, or RS485, allowing for easy integration into digital systems.
- Display and Alarms: Many handheld or industrial IR sensors include built-in displays, alarms, and data logging capabilities.
When and Where to Use Infrared Temperature Sensors:
-
Measuring Moving and Rotating Objects: IR sensors are ideal for measuring the temperature of moving or rotating objects, such as conveyor belts, rotating machinery, or motors, where contact sensors would wear out or be impractical. Example: Monitoring the temperature of rolling steel in a mill, checking the temperature of tires on a vehicle.
-
High Temperature Environments: Use IR sensors in environments where temperatures are too high for contact sensors, such as furnaces, kilns, or molten metal.
-
Hazardous and Inaccessible Locations: IR sensors are perfect for measuring temperatures in hazardous environments or hard-to-reach locations, such as high-voltage electrical components or distant objects. Examples: Monitoring the temperature of live electrical circuits, checking the temperature of a chimney or vent from a safe distance.
-
Thermal Imaging and Diagnostics: IR thermal imaging cameras are used for detailed temperature mapping and diagnostics, identifying heat patterns and anomalies.
-
Rapid Temperature Changes: Use IR sensors in processes where temperatures change rapidly, and real-time monitoring is crucial.

Considerations for Selecting and Designing Temperature Sensors
Different types of sensors work on different operating principles and choosing the sensor for any particular application requires knowledge of that application’s critical specifications such as accuracy, sensitivity, response time, temperature range, and other factors.
Calibration plays an important role in ensuring consistency between the sensor’s output and the actual temperature being measured. Calibration should be performed regularly, especially after prolonged use of the sensor or changes in environmental factors surrounding the system.
Proper shielding should be used to avoid EMI (Electromagnetic Interference) from surroundings. EM interference can significantly change a sensor’s measured values from the actual temperature value specially when high sensitivity is involved.
In the design phase, it’s also crucial to consider how to handle and transmit sensor data, which may involve using microcontrollers, data processing algorithms, and communication protocols.
