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 sensors commonly used models, mainly the use of non-contact temperature measurement. With the development of infrared technology, radiation thermometry gradually extended from the visible to the infrared, below 700 ℃ until room temperature has been adopted, and high resolution. Temperature sensor calibration standard techniques and indicators: 1, measurement accuracy: 0.01; resolution 0.1uV and 0.1mΩ; 2, scanning switch parasitic potential: ≤0.4μV; 3, temperature range: ambient + sink :( 5 to 95) ℃ sump: (95 ~ 300) ℃ low temperature bath: (- 80 ~ 100) ℃ high temperature furnace: (300 ~ 1200) ℃; 4, temperature stability: better than 0.01 ℃ / 10min (tank, sink, cryostat slot); 0.2 ℃ / min (test tube furnace); 5, the total uncertainty: thermocouple temperature sensor calibration, measurement uncertainty is better than 0.7 ℃ temperature sensor specifications, repeatability error <0.25 ℃; thermal resistance measurement test Uncertainty is better than 50mk, repeatability error <10mk 6, verification number: one can simultaneously check the thermocouple (1-8) temperature sensors supply branch, one can simultaneously check with wire RTD (1-7) branches; 7 Power supply: AC220V ± 10%, 50Hz, and have a good grounding protection; 8, furnaces power: 2KW; 9, bath power: 2KW; 10, computer monitoring and control system power: <500.
