For many, thinking about temperature does not extend far beyond the weather and how it will affect their day-to-day lives. However, in the context of engineering and innovation, the importance of detecting and monitoring temperatures goes far deeper. While few people know exactly what they are and what they do, temperature sensors are an extremely important piece of technology from an engineering standpoint. This guide breaks down all the key information on these powerful devices.
What Are Temperature Sensors?
A temperature sensor is an electronic device that measures the temperature of the environment. It then converts this input data into electronic data and enables the recording, monitoring, and signaling of changes in temperature.
What Are Some of the Common Uses of Temperature Sensors?
Temperature sensors have numerous uses across several industries. One example is the automotive industry, which requires the use of thermistors. Thermistors are installed in cars to measure oil and coolant temperatures and to trigger warning lights when needed (i.e. to avoid engine damage).
You will also find temperature sensors being used in infrastructure and commercial building. Given that temperature regulation in human-occupied buildings is an important priority, it is only sensible that temperature sensors would be used in contexts such as heating or cooling your home in the winter or summer months to keep you comfortable. This principle is the same in commercial buildings (e.g. office buildings, shopping malls) to keep patrons and/or workers at a comfortable temperature.
The food and beverage industry relies quite heavily on the effective use of temperature sensors. It’s essential that food – particularly meat and dairy products – are stored at the correct temperatures to prevent spoiling. It is also vital that these foods be prepared and cooked at the correct temperatures to avoid undercooking or overcooking, as these could lead to health issues.
Temperature sensors are also used in certain healthcare devices, such as contactless thermometers, which are becoming increasingly prevalent in the face of COVID-19. These thermometers feature several infrared sensors which take quick readings of temperature without directly touching the skin. Not only are the readings incredibly accurate, but this process is far less invasive for the individual who is being tested.
Where to Get Temperature Sensors
There are several temperature sensor retailers from whom you can purchase these devices. Pyrosales is an excellent example of an Australian temperature sensor manufacturer that offers a wide variety of temperature sensors, including glass industry sensors, food industry sensors, thermowells, thermal imaging devices, and resistance thermometers.
Temperature sensors have powerful capabilities that can be applied across multiple sectors, including the automotive industry, infrastructure and commercial building, the food industry, and even healthcare. In familiarizing yourself with what temperature sensors are, how they are used, and where to get them, you will improve your overall understanding of the important purpose these devices serve in society as well as how you might be able to use them yourself.
