Thermistor vs thermostat – which one is the proper word? The answer is that both are proper words, but they refer to different things. A thermistor is a type of resistor that changes its resistance with temperature. On the other hand, a thermostat is a device that is used to regulate temperature by turning a heating or cooling system on or off.
In this article, we will explore the differences between thermistors and thermostats, how they work, and where they are used. We will also look at the advantages and disadvantages of each and how to choose the right one for your needs.
Thermistor
A thermistor is a type of resistor that changes its resistance with a change in temperature. The word thermistor is a combination of the words “thermal” and “resistor”. Thermistors are made from ceramic or polymer materials and are commonly used in electronic devices to measure temperature.
There are two types of thermistors: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). NTC thermistors have a negative resistance-temperature coefficient, which means that the resistance decreases as the temperature increases. PTC thermistors have a positive resistance-temperature coefficient, which means that the resistance increases as the temperature increases.
Thermostat
A thermostat is a device that is used to regulate temperature. It is commonly used in heating and cooling systems to maintain a desired temperature range. The word thermostat is a combination of the words “thermal” and “stat”, which means “to control”.
Thermostats work by sensing the temperature of a room or area and then activating or deactivating a heating or cooling system to maintain the desired temperature. There are several types of thermostats, including mechanical thermostats, digital thermostats, and programmable thermostats.
| Thermistor | Thermostat |
|---|---|
| Changes resistance with temperature | Regulates temperature |
| Used to measure temperature | Used to maintain temperature |
| Two types: NTC and PTC | Several types: mechanical, digital, programmable |

Household Heating And Cooling Systems
In household heating and cooling systems, thermostats are the most commonly used option. They are designed to maintain a specific temperature range by turning the heating or cooling system on or off as needed. The thermostat measures the ambient temperature in the room and adjusts the system accordingly. In this context, a thermistor would not be an appropriate choice, as it is not designed to control a system in the same way as a thermostat.
Automotive Applications
Thermistors are often used in automotive applications to measure the temperature of the engine, transmission, and other components. They are ideal for this purpose because they are small, accurate, and can operate in a wide range of temperatures. In contrast, thermostats are not typically used in automotive applications, as they are not designed to measure temperature in the same way as a thermistor.
Industrial Processes
In industrial processes, both thermistors and thermostats can be used, depending on the specific application. For example, a thermostat might be used to control the temperature of a furnace or oven, while a thermistor might be used to monitor the temperature of a chemical reaction. In this context, the choice between thermistor and thermostat will depend on the specific requirements of the process.
Medical Devices
Thermistors are commonly used in medical devices to measure body temperature. They are small, accurate, and can provide a quick reading. In contrast, thermostats would not be suitable for this application, as they are not designed to measure temperature in the same way as a thermistor.
Overall, the choice between thermistor and thermostat will depend on the specific context in which they are used. Both have their own strengths and weaknesses, and it is important to choose the right one for the job to ensure accurate and reliable results.
Exceptions To The Rules
While thermistors and thermostats are commonly used for temperature control, there are some exceptions where the rules for using them might not apply. Here are some examples:
1. High Temperature Applications
Thermistors are typically designed for use in low- to medium-temperature applications, with a maximum temperature rating of around 300°C. In high-temperature applications, such as industrial processes or aerospace applications, thermistors may not be suitable due to their limited temperature range. In these cases, a thermostat with a higher temperature rating may be necessary.
2. Rapid Temperature Changes
In applications where the temperature changes rapidly, such as in a heating or cooling system, a thermistor may not be able to respond quickly enough to provide accurate temperature control. This is because thermistors have a slower response time compared to thermostats. In these cases, a thermostat may be a better choice for temperature control.
3. Specific Temperature Ranges
While thermistors and thermostats are both used for temperature control, they are designed to operate within specific temperature ranges. In some cases, the temperature range required may fall outside of the range that either device is designed for. For example, if a specific temperature range is required for a medical application, a custom-designed temperature control device may be necessary.
4. Size Constraints
Thermistors are typically smaller than thermostats, making them ideal for use in applications where space is limited. However, in some cases, a larger temperature control device may be necessary to accommodate additional features or components. In these cases, a thermostat may be a better choice.
While thermistors and thermostats are both useful for temperature control, there are exceptions where one may be more suitable than the other. By understanding the specific requirements of your application, you can choose the best temperature control device for your needs.
