Chinese name: application scope of platinum resistance: design principle, application scope, graduation table, components, characteristics, curves and charts, design principle of medical, satellite and other high-precision temperature equipment: 100, after which PT means its resistance is 100 ohm at 0℃, and about 100℃. Its working principle: when PT 100 is at 0 degrees Celsius, its resistance value is 100 ohms, and its resistance value will increase at a constant speed with the change of temperature. Scope of application High-precision temperature equipment such as medical treatment, motor, industry, temperature calculation, satellite, meteorology and resistance calculation. Has a wide range of applications. Graduation table -50 degrees 80.3 1 ohm -40 degrees 84.27 ohms -30 degrees 88.22 ohms -20 degrees 92. 16 ohms-10 degrees 96.09 ohms 0 degrees 100.00 ohms 10.

Ni (or Pd) leads are fixed with glass powder and made into thin film elements by laser resistance adjustment. The resistance value of the characteristic conductor changes with the temperature, and the temperature of the measured object can be calculated by measuring its resistance value, which is the working principle of the resistance temperature sensor. Pt 100 sensor takes advantage of the characteristic that the resistance of platinum resistor shows a certain functional relationship with the temperature change, and the corresponding relationship between temperature and resistance is: (1)-200℃
