Temperature Sensor - Non-contact temperature measurement advantages: measurement limit the degree of temperature sensing element is not limited, so there is no restriction on the maximum temperature can be measured in principle. For temperatures above 1800 ℃ temperature sensor, the main use of non-contact temperature measurement. With the development of infrared technology, radiation thermometry gradually extended from the visible to the infrared temperature sensor specifications, until the room temperature below 700 ℃ temperature sensors supply has been adopted, and high resolution. Note that the choice of 1, the temperature of the measured object is to be recorded, alarm and automatic control, the need for remote measurement and transmission; 2, temperature range of size and accuracy requirements; 3, the temperature element size is appropriate; 4, after being object temperature measurement occasions over time, temperature measurement devices can adapt to temperature hysteresis requirements; 5, the environmental conditions of temperature measurement devices measured object if there is damage; 6, the price of such security, is easy to use.
