| notes：
Ⅰ、t Is the absolute value of the measured temperature;
Ⅱ、The graduation number Pt100 is IEC standard, JPt100 is old Japanese and American standard Ⅲ、Φ 3 The following components are only allowed to use ≤ 300 ℃, Φ 4～ Φ 8 Generally, it can only be used at ≤ 550 ℃, especially 850 ℃ Ⅳ、Class A allowable deviation is not applicable to platinum thermistors with two-wire system |
| | （3）Working principle of thermal resistance | | A temperature sensor that measures temperature by using the characteristic that the resistance value of conductor or semiconductor changes with temperature. | | （4）Basic form of thermal resistance profile | 
| | （5）Temperature sensing elements include ceramic platinum resistance, glass platinum resistance, thick film platinum resistance, thin film platinum resistance, mica platinum resistance and copper resistance |
