Information

According to the method of temperature measurement, it can be divided into two categories: contact pyrometer and non-contact pyrometer.

The non contact pyrometer is currently mainly based on radiation temperature measurement in the industry. Its characteristic is that no part of the temperature measuring element is in contact with the object to be measured, but through the heat radiation between the object to be measured and the temperature sensing element. The function realizes temperature measurement, so it will not damage the temperature field of the measured object. It can not only measure the temperature of moving or rotating objects, but also measure the temperature distribution on the surface of the object by scanning. It has a fast reaction speed and a very light temperature measurement range. In principle, it is not restricted by the upper limit of temperature. It is usually used to measure the temperature of moving, rotating or fast-reacting high-temperature objects above 1000°C. However, it is affected by some factors. The accuracy of temperature is generally not high.

When any two objects with different degrees of cold and heat are in contact, heat exchange will inevitably occur. The heat will be transferred from the object with high degree of heating to the object with low degree of heating, until the degree of cold and heat of the two objects is exactly the same, that is, the state of thermal equilibrium is reached. . Contact method temperature measurement is to use this principle to select an object to contact with the object to be measured, and conduct heat exchange. When the two reach a thermal equilibrium state, the temperature of the selected object and the measured object are equal, so the temperature value of the measured object can be obtained by measuring a certain physical quantity of the selected object.

From the above, we can know that measuring temperature is also exquisite. We should pay attention to different measurement methods so that accurate temperature values ​​can be measured.

We can feel different temperatures in different environments. If we want to know the specific temperature, we can use different temperature measuring instruments such as bimetal thermometers, electronic thermometers, pressure thermometers and other instruments to measure them. So, how to measure temperature?

The high temperature temperature cannot be measured directly. It can only be measured indirectly with the help of heat exchange between objects with different cold and heat, and some physical properties of the objects change with different degrees of cold and heat.

So what are the conditions for measuring substances with non contact pyrometer?
1) A continuous single value change with temperature.
2) Not affected by other factors.
3) Easy and precise measurement.
