Temperature sensor, application and buying notes
Currently in the field of manufacturing and industry we often use 4 common measurement quantities: temperature, pressure, flow and level. These are quantities that play a very important role and are an indispensable part of every technology chain.
- Currently in the field of production and industry we often use 4 common measurement quantities: temperature, pressure, flow and level. These are quantities that play a very important role and are an indispensable part of every technology line. In the article below, we will help you learn some information and applications of temperature sensors in industries.
What is a temperature sensor?
- First, before knowing what a temperature sensor is used for and where it is applied, we need to know what a temperature sensor is. If you are a layperson, you can understand this in a nutshell: the temperature sensor is made of metal or semiconductor materials with resistance values that change according to temperature or reverse bias current, layers The junction will change when affected by temperature. For those who specialize in engineering, temperature sensors are understood as non-electrical physical quantities converted into electrical signals, then temperature sensors are used to measure, count, sense temperature....

- The accuracy of the temperature sensor will depend on two factors: the temperature of the environment and the temperature of the sensor. If the temperature transmitted from the environment to the measuring head of the thermal sensor is less, the more accurately the sensor temperature will be measured. This depends on the material that makes up the sensor elements.
- The material of the sensor is the standard to calculate the accuracy of the environment to be measured. Therefore, you need to pay attention to the following issues if you want to buy a good thermal sensor.
- Accuracy: because this is a temperature measuring device, it requires extremely high accuracy. In case we encounter an unacceptable temperature level, we need to adjust the temperature and reduce the temperature to an acceptable level so as not to cause a fire or explosion.
- Flexibility and easy installation. Most current sensor devices require mounting and replacement functions in case a part of the device is damaged and needs to be replaced or moved more neatly.
- Temperature limit to measure: This is a very important factor when you want to buy heat-sensing devices. To help avoid waste and help the thermal sensor maximize its capabilities, we need to pay attention to the sensor's limit and choose a suitable thermal sensor.
