What is the range error of the temperature sensor?
Depending on the manufacturing process, the measurement range of the temperature sensor is different.
Ceramic platinum thermal resistance can measure the widest temperature range, -200～800℃, and now it can reach -250～850℃.
Mica platinum thermal resistance, due to the characteristics of mica, its temperature range is -200～420℃.
Because of its packaging and manufacturing characteristics, the temperature measurement range of thin-film platinum thermal resistance is -50～500℃.
The accuracy of temperature sensors with different principles and processes will vary.
Temperature sensors are widely used and have a wide variety of types, roughly including the following types:
Thermal resistance, thermocouple, PN junction temperature sensor, integrated temperature sensor, acoustic temperature sensor, infrared sensor and microwave sensor.
1. PT100 has high accuracy.
In the national standard, pt100 is divided into A and B levels;
Measuring range: -200℃～+850℃
Class A accuracy is (0.15+0.002*|t|) degrees Celsius;
Class B accuracy is (0.30+0.005*|t|) degrees Celsius; where |t| is the absolute value of the actual temperature.
2. The integrated temperature sensor has a higher accuracy of ±0.2℃.
3. The general accuracy of temperature sensors used in clinical thermometers can reach ±0.1℃.
