Perbedaan utama antara RTD dan PT100 adalah bahan yang digunakan untuk elemen penginderaan: PT100 adalah jenis spesifik resistor termal RTD, dan namanya berasal “Platinum” (platinum) Dan “100” (100 ohm pada 0 ° C.). Ini adalah sensor RTD yang paling umum digunakan dan banyak digunakan dalam kontrol proses industri, pengukuran laboratorium dan bidang lain yang membutuhkan pemantauan suhu presisi tinggi. Keuntungan PT100 termasuk:

The thermal resistance formula is in the form of Rt=Ro(1+A*t+B*t*t);Rt=Ro[1+A*t+B*t*t+C(t-100)*t*t*t], t represents Celsius temperature, Ro is the resistance value at zero degrees Celsius, A, B, C are all specified coefficients, for Pt100, Ro is equal to 100℃.

A PT100 sensor acquires temperature by measuring the change in its electrical resistance, which directly correlates to the temperature it is exposed to; Saat suhu meningkat, the resistance of the platinum element within the sensor also increases, allowing for a precise calculation of the temperature based on this resistance change; essentially, the “100” in PT100 signifies that the sensor has a resistance of 100 ohm pada 0 ° C., and this value changes predictably with temperature fluctuations.

Platinum resistors are widely used in the medium temperature range (-200～650℃). At present, there are standard temperature measuring thermal resistors made of metal platinum on the market, such as Pt100, Pt500, Pt1000, dll..

The temperature measurement range of the commonly used platinum resistance Pt100 sensor probes is -200～850℃, and the temperature measurement ranges of Pt500, Pt1000 sensor probes, dll.. are successively reduced. Pt1000, temperature measurement range is -200～420℃. According to the IEC751 international standard, the temperature characteristics of the platinum resistor Pt1000 meet the following requirements:
