The contact part of the contact temperature sensor has a good contact with the measured object, also known as thermometer

The thermometer achieves heat balance by conduction or convection, so that the indication of the thermometer can directly indicate the temperature of the object to be measured.

Generally, the measurement accuracy is high. In a certain range of temperature measurement, the thermometer can also measure the temperature distribution inside the object. But for the motion of the object body, small objects or very small heat capacity will produce large measurement error, the commonly used thermometer with double metal thermometer, glass liquid thermometer, pressure type thermometer, resistance thermometer, thermocouple and thermal resistance etc.. They are widely used in industrial, agricultural, commercial and other sectors. These thermometers are often used in daily life.
