5 Different Types of Thermometers and Their Applications
A thermometer is a device that measures temperature or temperature differential in degrees using the Celsius or Fahrenheit systems. It is made up of two components: a temperature sensor that fluctuates in response to temperature changes and a mechanism that converts the temperature change into a numerical value. The temperature of a substance is a physical quantity that expresses how hot or cold it is. It indicates the thermal energy present in all substances. Thermometers are widely used in a variety of industries, including meteorology, scientific research, medicine and technology. However, not all thermometers are designed to function in the same way or to offer similar readings. Meteorologists use thermometers to determine how hot or cold the weather is, whereas doctors use them to monitor a patient’s body temperature. There are multiple variations of the device available for different purposes, ranging from mercury thermometers to compact infrared thermometers. Therefore, it is critical that you are well-informed about the various options available to you before making a purchase.
So, let us explore the different types of thermometers and how they are utilised on a regular basis by various industries.
Probe Thermometers
Probe thermometers, one of the most common and widely used thermometers, are typically used to collect real-time temperature measurements of food and liquid samples. They are ideal for hygiene testing at retail outlets and food sector laboratories due to their fast temperature readings. Probe thermometers have a pointed tip to facilitate immersion and penetration and are available in two varieties: fixed probes and wired probes.
Infrared Thermometers
Infrared thermometers are a popular choice when it comes to non-contact temperature measurement. They are an excellent tool for measuring extremely high or low surface temperatures. They often contain a laser targeting system that indicates the centre of the measurement area. There are also compact infrared thermometers that are quick and accurate, which you can use on the go.
Infrared thermometers have a wide range of applications, including air conditioning systems and the automotive trade. They are also useful in high-temperature manufacturing processes, medical applications, and electrical repairs.
Digital Thermometer
Most digital thermometers employ heat sensors to detect the temperature of the human body. They also feature an electronic circuit and a display screen to showcase temperature readings. Generally used for medical purposes, these thermometers take readings from under the tongue, under the armpit or the rectum. They are more advanced and more accurate compared to traditional thermometers. These instruments are affordable, easy to use, and widely available.
Bimetal Thermometer
Bimetal thermometers, which are made of two distinct metals, are typically used in industrial settings. They are reasonably priced and simple to install and use. The metals are bound together, causing them to expand at varying rates and lengths when the temperature rises. The functional premise of bimetallic strip thermometers is that metal expands differentially depending on temperature change. They are employed in a wide range of industrial applications, including air conditioning and refrigeration technology, heating technology, and machine building.
Platinum Resistance Thermometer
The platinum resistance thermometer uses a platinum wire to detect temperature. It operates on the principle that the resistance of platinum varies with temperature. Platinum is used as a sensing element in these thermometers due to its properties. The wire is linked to an electrical resistance that changes in response to temperature. As a result, when the temperature increases, so does the resistance of the materials used.
