What is RTD PT100?
PT100 ek Resistance Temperature Detector (RTD) sensor hai jo industrial temperature measurement ke liye use hota hai. PT100 ka matlab hai ki sensor ka resistance 0°C par exactly 100 Ohms hota hai.
How PT100 Works?
Jaise-jaise temperature increase hota hai, PT100 sensor ka resistance bhi increase hota hai. Yeh bahut accurate aur stable temperature sensor mana jata hai.
PT100 Advantages
- High Accuracy Temperature Measurement
- Long Life Sensor
- Industrial Standard Sensor
- Better Stability than Thermocouple
- Noise Resistance Better Hoti Hai
Standard PT100 Resistance Table
| Temperature (°C) | Resistance (Ω) |
|---|---|
| 0 °C | 100.00 Ω |
| 50 °C | 119.40 Ω |
| 100 °C | 138.51 Ω |
| 150 °C | 157.33 Ω |
| 200 °C | 175.86 Ω |
Agar multimeter par PT100 sensor Open Loop, OL ya Mega Ohms show kare toh sensor internally damaged ya break ho sakta hai.
RTD Wiring Types
2-Wire RTD
Simple wiring hoti hai lekin lead wire resistance ki wajah se thoda error aa sakta hai.
3-Wire RTD
Industrial field mein sabse zyada use hota hai kyunki yeh lead resistance compensation karta hai.
4-Wire RTD
Sabse accurate method hota hai aur laboratory applications mein use hota hai.
