What kinds of temperature sensors are there?
Temperature sensors can be divided into two categories: contact type and non-contact type according to the measurement method, and are divided into two categories: thermal resistance and thermocouple according to the characteristics of sensor materials and electronic components. A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument.
What kinds of temperature sensors are there?
The detection part of the contact temperature sensor has good contact with the measured object, also known as a thermometer. The thermometer achieves thermal equilibrium through conduction or convection, so that the indication value of the thermometer can directly represent the temperature of the measured object. Generally, the measurement accuracy is high. In a certain temperature measurement range, the thermometer can also measure the temperature distribution inside the object.
The sensitive element of the non-contact temperature sensor is not in contact with the measured object, also known as the non-contact temperature measuring instrument. This instrument can be used to measure the surface temperature of moving objects, small targets and objects with small heat capacity or rapid temperature changes (transient), and can also be used to measure the temperature distribution of temperature fields.
