7 Most Common Types of Temperature Measurement Sensors

Posted by Ali Tariq on June 27th, 2022

Temperature measurement devices are tools used to measure the temperature of a substance or object. They come in a variety of forms, including thermometers, infrared thermometers, and laser thermometers. Each type of device has its own strengths and weaknesses.

Thermometers are the most common type of temperature measurement device. They work by measuring the expansion or contraction of a liquid or gas that is in contact with the object being measured. This type of device is inexpensive and easy to use, but it can be inaccurate in extreme temperatures.

1. Thermocouples:

Thermocouples are one of the most common types of temperature instruments. They are made up of two dissimilar metals that create a small electric current when they are at different temperatures. This current is measured and converted into a temperature reading.

Thermocouples are used in a wide variety of applications, including ovens, HVAC systems, and medical devices. They are reliable and inexpensive and can be used to measure temperatures over a wide range of -270 degrees Celsius to +1300 degrees Celsius.

2. Resistive temperature measuring devices:

There are many different types of temperature measuring sensors, but resistive temperature devices are one of the most common. These sensors are made up of two wires, which are placed in close proximity to each other. A current is run through the wires, and the voltage that is generated is proportional to the temperature. This type of sensor is very accurate and can be used in a wide variety of applications.

3. Infrared sensors:

An infrared sensor is a device that measures the temperature of an object by detecting the heat that is emitted from it. This type of sensor is one of the most common types of temperature measuring sensors. They are used in a wide variety of applications, including automotive, industrial, and consumer electronics.

4. Bimetallic devices:

A bimetallic device is a temperature measuring sensor made from two different types of metal. When the temperature of the device changes, the metals expand at different rates, causing the bimetallic strip to curl. This curl can be used to activate a switch, which in turn can be used to power an electric circuit or start a motor.

Bimetallic devices are one of the most common types of temperature measuring sensors. They are inexpensive to produce and can be used in a wide variety of applications. Bimetallic devices are also relatively accurate and can be used to measure temperatures ranging from 40 to 800 °F.

5. Thermometres:

Thermometers are devices used to measure temperature. There are many different types of thermometers, but the most common type is the mercury thermometer. Other types of thermometers include the alcohol thermometer, the clinical thermometer, and the digital thermometer.

The mercury thermometer was invented by Galileo in the 16th century. It is a glass tube filled with mercury, which expands and contracts as the temperature changes. This causes the level of mercury in the tube to move up and down, and this movement can be read to determine the temperature.

6. Change-of-state sensors:

There are many different types of temperature measuring sensors, but one of the most common is the change-of-state sensor. This type of sensor is very simple – it detects a change in temperature and then sends that information to a controller. Change-of-state sensors are often used in industrial applications where there is a need for fast response time and accuracy.

One of the benefits of using change-of-state sensors is that they can be used in a variety of applications. They can be used in air conditioning and refrigeration systems, automotive systems, and many other types of systems.

7. Silicon diode:

Silicon diodes are one of the most common types of temperature measuring sensors. They are used in a variety of applications, including temperature measurement and control, power supplies, and motor drives. Silicon diodes are also used in a variety of industrial and commercial settings.

Silicon diodes are made of silicon, which is a semiconductor material. This type of diode is used to measure temperatures because it has a very low thermal resistance. Silicon diodes are available in a variety of packages, including TO-92, SOT-23, and SOIC-8.

So these are some of the most common temperature measurement devices that are used in different industries and in different places to measure the temperature.
